Voltcraft VC870 - Any experiences?
<< < (4/9) > >>
Leon:
I can certainly snap some pictures and write some text about it. What would you like to see covered?
Note: it may take a while as I'm pretty busy right now.
Lightages:
If you could, take some general images of the outside, with the battery/fuse access door off, and take it apart and show the insides. Maybe say some things about the update rate, auto ranging speed, and continuity test response. That should give us an idea what it is like.
Leon:
I promised to take some pictures but like I said: busy, busy, busy. I'd love to be able to say more about the update rate, auto ranging speed, etc. but the truth is I can only compare it the Fluke 89IV at work. I don't collect DMMs, I simply work with them and I'm only measuring resistance and VDC most of the time. Compared to the Fluke at work, the VC890 is faster on most parts except things like the continuity measurement: the buzzer doesn't always work, but the measurements do show the short in the display. Judging from Dave's video the VC890 does seem to buzz a lot faster than the Agilent U1253.

On to the pictures:
I ordered my VC890 with a VC-511 clampadapter (for about 9 euro extra) and use different leads.

The box contains the meter itself, a temperature sensor, an optical to USB connection cable, CD with software, leaflet and 2 sets of leads: one standard, one very short with crocs.

The display is what sets this unit apart from the normal UNI-T models: it's an OLED display (much like the Agilent U1253). Update rate is good, esp. the bar works like a joy. As shown, the meter is perfectly readable from an angle. The brightness of the display also makes this meter very easy to use in dim light conditions.

The rear shows the optical connector for the USB cable, and of course the door.

The door slides down, and through some latches you can't open the door while there are leads connected and leads can't be inserted while the door is open. A simple but effective method to deter those stupid enough to want to touch the fuses while measuring 1000V.  ;D

As said, the fuses are ceramic plus they are of the correct rating. The meter comes with a 9V GP alkaline battery, but it can also be used with a 9V rechargable lithium pack (which Conrad also sells). The type of battery can be selected from the menu.

With the back removed you can see the latches, some shielding and padding for the CR2032 RTC battery.

I did a partial teardown, and this meter is built around a standard 60000 count DMM chip from Cyrustek: the ES51997. See: http://www.cyrustek.com.tw/spec/ES51997F.pdf

A few detail snaps of the inside, chip, fuses and that's it.
Lightages:
Wow! It looks like Uni-T has finally made a multimeter with some real though for the input protection.  :scared:

It certainly looks like a nice meter. Unfortunately it costs $200 USD and Conrad wants an additional $67 to ship to me!!!
SyncOnGreen:
Excellent information on the Voltcraft VC890!! Thanks very much Leon!
I am very tempted to buy this DMM @ Conrad, as a replacement for my old, now defective Tektronix  :-DMM and is within my budget.

However, I still have a few questions that also might be of interest to others:
1. How is battery life compared to the Agilent OLED DMM's (8 Hours)?
2. Is the OLED display of the VC980 visible outdoors in daylight?

Thanks in advance! Cheers!
