Hi!
I do some hobby electronics repair and have been looking for a semi-decent LCR meter with ESR measuring capability. I have been looking for a nice price Mastech MS5308 or similar. I want to be able to do some in circuit component testing.
Somehow, I just became highest bidder on an ebay Philips PM6303. Of course, I hope it is worth the US $89.88 bid + US $75 shipping with USPS Express Mail® International (The express option saves me $41 in customs declaration fee at the mail office).
Here is a 1991 brochure: http://www.teknetelectronics.com/DataSheet/PHILIPS/PHILI_630395255.pdf
The ebay description of the PM6303 RCL Meter and the PM9542 Test Adapter is as follows:
"Fluke/Philips RCL MeterModel# PM6303 in good condition, items powers up.
All items are sold as is."
One of the fuzzy pictures shows the meter turned on with the test adapter plugged in without any other connections (8 banana posts not connected to anything).
The LCD display of the meter reads 6.30 kH and shows the capacitance symbol and the inductance symbol in series. "RCL Auto" LED is lit.
I have never used such an instrument. Should I worry about the readings on the display, or are they plausible of a good meter? I will be happy for any comments regarding this.
If it works, I hope the meter will be a good companion, even though it only has 1 KHz measuring frequency.

I don't know anything about this meter until now, so can't help you there. However, I was able to find a PDF user manual, which is attached.

It appears to be a very capable LCR meter for making spot checks, if working its certainly more affordable than modern hand held LCR meters. The standard test frequency for most spec sheets is 1kHz, so its a simple way to confirm basic specifications. In specific applications, like RF or switch mode capacitors, the spec sheets may be derived using other frequencies, but these are less common usages; as always its good to confirm the test frequency before making comparisons.
-
That's an absolute bargain!

Oh, I just realised it's the old model, and not the new model:
Still should be a nice meter though.

Thank you for enclosing the manual. Looks pretty straight forward to convert from 110 to 238 volts. -

I presume 1kHz is perfectly good enough for my needs. -
Good LCR meter there, and it does work on 220V. Nice in that it can bias up to 2V for checking capacitors with no problems. I did use one to check 2000 capacitors, it was as fast as me to do the checking. Still took 2 days to get through them all.

I was really happy to read this comment, Dave. Still happy, even after reading your next post.
It seems these meters (even old model) are pretty expensive on ebay. Wonder why the highest bid was an order of magnitude
lower this time.
The accuracy and resolution seems pretty awesome. The measuring span is also impressive
-
I still fear that the 6.30 kH on the LCD display means there is a major malfunction. I there a plausible reason for such a reading on a working meter?
-
Think about it... what would the characteristics of a 6300H inductor be? You could apply a voltage across it for a short time, but the current would ramp up so slowly you'd be lucky to measure any current at all. Over a short timescale, it would be hard to distinguish from an open circuit.
-
Misadjusted zero setting, then the meter is overcompensated and thinks it has a realllllllllllly big inductor connected to the terminals when the probe assembly is removed. Plug in the 4 lead assembly with nothing in it then it will read 0.0pF.
-
Thank you, AndyC and SeanB for your comments that made me quite a bit calmer.
If it should be of interest to anyone looking for RCL meter, there are no bids on a $ 50 meter on ebay with 1 day left: "LCR Meter by Tenma 72-370 w/case"
I dont know the specs, but it may be a useful meter... -

Hope you at least caught one bad cap

Its a defacto standard for testing L & C. But on occasion, spec sheets are made using 10k or 100kHz, just keep an eye out when testing them. DCV bias of 2V is ok for general testing, but be skeptical about it because in actual use DC bias changes should be close to the operating voltage of most circuits, typically 5-12V, if true capacitance is critical to you. Bias for L is different, which is in current, and requires a current source but is not included in this LCR meter.

Hi,
I have a newly purchased when he first came on the market ~1984.
Yes very expensive...
He gets used almost every day and is very fast in detecting the DUT.
Switch on in 5 second and stable in 15 seconds, almost no drift.
In 28 years i have one replace'd 1 capacitor, (3n3 polystyreen)
Except the power supply the is nothing to calibirate :-)
It's a nice instrument!
Kind regarts,

maybe I'm doing something wrong, but there is not one completed listing for a 6303 that went for that on eBay across all TLDs. link to auction plz?

The ebay "completed listings" search is a bit useless, it's often better to use google to trawl through ebay past sales even though it isn't easy to search all the ebay domains.
That said I can't see anything matching the OP's purchase...... -
I used to see the "completed listings" on ebay.
I cannot see anymore.
Is this related with my settings? How do you get there? -

Not sure if there's a user setting that could remove it but it's possibly country specific.

It should be in the advanced search options though. -
Hi! I have removed the specific ebay auction link until the item is shipped. I haven't heard from the seller after I won the auction. Hope he replies to my questions and payment as soon as the turkey & stuffing is properly processed.
Now I have to get a four-wire kelvin clip and some SMD tweezers. -
The item is still not shipped and I have not heard from the seller since December 19.
Maybe he has gone under cover?
December 28 the item was somehow marked as shipped and I was provided a tracking number. The status of the item is still "Electronic Shipping Info Received", meaning "The U.S. Postal Service was electronically notified by the shipper on December 28, 2012 to expect your package for mailing. This does not indicate receipt by the USPS or the actual mailing date."
What is really strange is that this seller has sold more than 600 items on ebay and has a 100,0% positive feedback score. What were the odds that the first transaction he should ever mess up was mine?
-
The seller has tricked me and probably will sell the PM6303 to someone else when he gets the chance. He pulled it off with some help from eBay Customer Support.
Link to item: http://www.ebay.com/itm/140898370484
Here is how he did it:
December 22. (D-day) I won the auction on ebay item 140898370484 with a bid of $89.88. Seller is cica93, alias Avstar Aviation LLC in Florida, alias Carl Weisse.
December 23. (D +1 day), I paid for the item and shipping.
December 28. (D + 6 days), USPS status page and tracking number shows that the items are being shipped with USPS
January 6. (D + 15 days), I informed the seller that " I have already ordered additional accessories (Kelvin clips and SMD device tweezers) to the PM6303 that you are about to ship. I am looking forward to you shipping the item soon." No change in shipping status. (eBay generated message title: "I haven't received my item yet: "nixxon" sent a message about Fluke/Philips LCR Meter #140898370484")
January 7. (D +16 days), I request seller's contact information based on the following explanation: Hi! I won an auction December 22 where cica93 is seller. (100,0% positive feedback and almost 700 items sold) I payed for the item + shipping soon after. I have emailed him multiple times about shipment method. I haven't heard from the seller since December 19. Should I regard this to be a possible problem? I want the seller to ship the item using USPS Express Mail International. December 28, I received a tracking number. Status today is still "The U.S. Postal Service was electronically notified by the shipper on December 28, 2012 to expect your package for mailing. This does not indicate receipt by the USPS or the actual mailing date." Please let me know what is good ebay practice for me to do in this situation. I really want the seller to ship this item. I have already bought complimentary equipment to be used with the won item as well. Best regards, "nixxon"
January 8. (D + 17 days), I open a case at Ebay Resolution Center: Here's what you need to do next:
Try to work things out with the seller. If you don't hear back by Jan 16, 2013, you can escalate this case to eBay Customer Support.
What you should know:
This case will automatically close on Feb 07, 2013 if the case is not escalated.
Details you've provided:
Problem: You have not received the item
You have already contacted the seller through eBay Messages
You paid on Dec 23, 2012
The seller has not responded to you
The seller isn't working with you to solve the problem
You entered the phone number of "+47 XXXXXXXX"
We can share your phone number with the seller.
Additional information:
"No reply from seller what so ever. I called (727)535-2600 multiple times, but only get a voice message telling me "You've reached a number that is disconnected or no longer in service". I really want this item, as I have invested in other hardware that go with this item only."
The seller has provided the shipping information for your item. You can view the shipping information in the Resolution Center.
If you receive the item, you can close the case in the Resolution Center.
Seller's message to you:

January 8., (D+ 17 days) answer from eBay Customer Service regarding request of seller's contact information the day before:
Hello "nixxon",
Thank you for contacting eBay; it’s my pleasure to assist you today.
I understand that you are concerned because the tracking of your item shows no progress since the 28th. Usually it’s best to give it time (I know it’s already been about 10 days) as sometimes USPS tracking is slower to update. However, if you have not received your item by January 21st, you should open a case for your item. To do that, go to:
http://resolutioncenter.ebay.com
Keep in mind that timing is important. You can open a case after the estimated delivery date has passed, or 7 days after you paid for the item (if no estimated delivery date was given). You must open a case within 45 days of making payment.
I know that it can be frustrating to wait that long for your item. However, as of right now I don’t see a reason to worry too much.
I hope this answers your question and I wish you all of the best with your future eBay experiences.
Very Respectfully,
Jerrick G.
eBay Customer Service
January 9., (D+18 days) Rather than shipping the items as promised this day, the seller contacts eBay and escalates the case:
Hi "nixxon",
The seller has asked eBay Customer Support to review this case and make a final decision.
We'll review the case details, such as messages sent in the Resolutions Center about this case and other emails sent through eBay between you and the seller. If we have questions, we'll get in touch with you. We'll get back to you within 72 hours.
You can view the details of this case in the Resolution Center.
January 9. (D+18 days), Message from Buyer Protection Team
Dear "nixxon",
We are sorry you are having an issue with the item you purchased. As a follow up on your eBay Buyer Protection case, we wanted to explain what you can expect from the process.
Important things to know :
The seller has been notified that you have not received your item and that you have opened a case in the Resolutions Center. Here are the next steps:
1.
The seller has a maximum of 7 days to respond to the case. Most sellers will respond with shipping status information or issue you a refund.
2.
If you are not able to work out a resolution with the seller, you need to escalate the case to eBay customer support to make a final decision.
For most items you can expect a final decision, and if we find in your favour, a refund within 3 days of making our decision.
3.
Your case will time out in 30 days from when it was filed, if we do not hear from you. Please return to the Resolutions Center before that to let us know that you and the seller worked things out or that you need eBay customer support to make a decision.
Action Required from you :
•If you are unable to work things out with the seller or do not hear back from them in 7 days, please respond to your case in the Resolution Center and choose the "Escalate" option.
What incentive is there for the seller to resolve your issue :
•Sellers have a strong incentive to fix your issue. eBay takes eBay Buyer Protection cases very seriously. Sellers who are found to cause repeated problems on the eBay site will be negatively impacted in their seller standings and possibly suspended.

January 10. (D+19 days), I write the seller: Hi cica93!I don't receive any replies from you regarding my Emails to you. Do you get my Emails?2 days ago, you wrote: "There was a problem with the shipping label, was fixed with paypal yesterday Jan 07, item will ship tomorrow Jan 09"The USPS tracking has not changed since December 28.Did you ship the item yesterday?Best regards,"nixxon".
January 10., (D+19 days) notification from eBay Customer Support:
Case # 5022130221: Customer Support made a final decision
Hi "nixxon",
Good news! We issued you a full refund of $164.51 on Jan 10, 2013. The refund includes the purchase price plus original shipping and has been credited to your PayPal account. Please log in to PayPal and view the History page if you don't see it in your PayPal balance.
Decision:
This case has been decided in your favor.
Comments:
We didn't receive valid tracking information from the seller. We're sorry you had a problem with your purchase, and we're issuing you a refund for this case.
***************************
There you have it. Above you find the recipe on how a seller can get away with it, bridging a contract, cancelling a deal and not shipping an item if he does not want to fulfill his part of an eBay deal. This way, the seller runs no risk by not having a minimum price and getting a relatively low highest bid for his items for sale.
Now I just need to find another PM6303 for $164.51 including shipping. For your infomation current PM6303's on eBay have minimum prices that vary between $865 and $1750. The $164.51 refund is $1100 short of covering the average price of the other PM6303 LCR meters that are for sale at present at ebay. That is excluding shipping cost. "Decision in my favor", my ass
I guess cica93 never intended to ship the item. Maybe he will change his mind if I let him know that I am disappointed
-
I am both sad and satisfied to announce that cica93 is down from 100.0% to 95.5% satisfaction on eBay.
I hoped and believed this would never happen.
Worst seller ever experienced. Pure fraud. Stay clear of this seller.
Why does a seller inflict this to himself? Beats me...
rest in peace, cica93...
(OK, I do I see the point that he could gain $1100 (short term gain) by ripping me off) -
Don't confuse the asking price in other auctions with actual selling price. Some sellers relist the same item for months at 5-10x market value, in the hope some desperate fool or company that needs the item at any price comes along.
