Yep, I think that's the one.
Could probably make a little slide in adapter that took some sort of standard size magnet (say 10mm dia) and allowed it to fit snug inside.
hello i have a question...
does 121GW multimeter have differential probe for measuring current? i want to measure current around more than 10 Amps on my device anyway
answer is really appreciated, thx before
A differential probe for... current? What is your use case?
Without more information or your requirements (AC or DC? Contactless or resistive current measurement? Are the sources isolated?), the following methods may work.
Multiple 121GW meters can connect to an Android device or Windows PC via Bluetooth, and math functions can be performed against the connected meters. You could simply take the subtraction of the readings between two connected meters.
Resistive:Contactless:
- 2x 121GW meters (or any oscilloscope with simple math functions + some milliohm-scale power resistors)
- An Android device or Windows PC (if using the 121GW)
- 2x 121GW meters (or any oscilloscope with simple math functions)
- 2x hall-effect current sensors, such as the PDI CA-60
- An Android device or Windows PC (if using the 121GW)
It may be more cost-effective (and offer greater insight) to use a cheap oscilloscope such as a Rigol DS1054Z than multiple 121GW meters. Depending on your requirements, you could also build a circuit to do this, and measure it with a single 121GW (or any other meter or oscilloscope).
But answer the specifically asked question: no, the 121GW doesn't have any differential probes.
Tweakage finished unless anyone who makes it finds an issue and I will see if it can be improved.
Hollowed out the release so it now has more flex, fattened up the front bar for more strength and short of hanging your toolbag on it shouldn't ever be a problem. Also increased the web at the rear of the release for more strength when being pressed. The release as it is here in PLA can be deflected down by about 3mm without any risk of breaking it and the urethane section of the bumper can easily be flipped over it then to release the hanger. Still recommend PETG if you have it (I will try one next time I have some loaded).
Print settings 6 layers all round 40% infill so basically solid at 0.2mm layers. Printed on edge with bed supports only, could fully support it but the one shown in this post wasn't. STL is in the Zip file attached here.
Hello,
an updated version (8th of August 2019) of the manual is online

Added battery voltage check to the firmware update pro-
cedure.
2.00
Improved the Auto-ranging reading speed in both ca-
pacitance and resistance ranges.
1. Ensure the low battery indicator is not present.

Looking at purchasing this. Mainly interested in the logging feature.

BLE logging is still very broken.

Broken isn't the right term but buggy is closer with the bluetooth. It has improved over the release version but would still benefit from more work on the app.
The logging data isn't where it should be as the 'precise timing' from the meter is bs and still needs fixing to something meaningful or sensible preferably at the meter end in firmware.
Precision, Accuracy etc are a matter of reference. You need to specify it to have a frame of reference. My biggest beef with the software/meter for logging is the BS timebase used not the 'accuracy' of the meter. The timebase can be post edited in a spreadsheet with a little maths but it shouldn't have to be.
Against my recently calibrated Keysight 34461A snd I haven't looked at recalibrating it against this and my in cal 34401A but it is well within the combined error margin of both.
Rough setup and plenty of possibilities for stray noise to play with the BT but looking for dropped results and NOPE.
30 minutes of logging with a rough setup as shown and lets look at the 'false recordings' and other random unsubstantiated claims of the Troll boy in chief - NOPE
I feel sorry for someone trying to research this meter for purchase. There is too much back and forth and these threads are ridiculous for trying to find the current status of the meter. I suppose an official page with all the firmware versions and known and fixed "concerns" listed out would be too much to ask for???
I have to say that I was a bit surprised at the official support for this meter when I came looking. Dave being Dave, I assumed that he would've been fairly thorough in providing this (official updates, notifications etc). There isn't even a readme file attached to the firmware zip.
Also I just discovered that there is hardware (pcb?) upgrade to fix (I assume) the rotary dial issue? Has this change been rolled out to for sale units?
Anyhow perhaps I'm being a bit too critical as I don't know the history behind the meter.
