After watching Balance Charging: Can you parallel charge?, I realised that I needed a clamp meter. But which one?
I had already purchased a UNI-T UT71D DMM, see Choosing which Multimeter to buy, and I was very happy with it, so the UNI-T clamp meter seemed a logical choice. Everyone seems to have the UNI-T 210E. However, there are a myriad of other options.
- There is a cheap version of the UT210E, NKTECH NK210E on eBay, NKTECH NK210E Digital Clamp Meter Multimeter AC DC Volt AC A Res VS UNI-T UT210E, £13.68, but does not appear to do DC current
- Which UNI-T clamp meter to buy?
- UT216D, same as UT216C, but with OLED. 60A/600A. Only UT216C has DC, down to 10 mA
- UT211B – no inrush
- UT207/208 have inrush and 208 has temp
- Which uni-t clamp meter is everyone using?
- UNI-T UT210D – no low current, up to 200A
- UNI-T UT204
- UT210E has low current 2A (1mA), only up to 100A, 2000 display counts
- UT211B – more stable than UT210E, 6000 display counts, worth the exta cost
- UNI-T UT210E True RMS AC/DC Current Clamp Meter Unboxing
- EEVblog #712 – Uni-T UT71E Multimeter (Why Uni-T Meters Suck) – UT71E, but only complains about the power measurement.
- UT216c ADC – shows some problems – in Russian
- UNI-T UT216C 600A True RMS Digital Clamp Meters, $54.80
- UNI-T UT216D Digital Clamp Meters 600A True RMS OLED Display AC/DC Tempreture te, $95.20
- UNI-T UT211B 60A True RMS Mini Clamp Meter AC DC Amp Volt Ohm Capacitance Tester, $60
- UNI-T UT210E Digital Clamp Meter Multimeter Handheld RMS AC DC Resistanc, $30
Hacking the UT210E
Unfortunately, not many UNI-TREND clamp meters do DC current. The main contenders are:
- UT216C is the best (features wise), and most expensive, but does not have very low currents (10mA) up to 600A
- UT210E is very popular, low currents (1 mA) up to 2/20/100A. 2000 display counts
- UT211B better stability than 210E (1mA) up to 6/60A. 6000 display counts, but twice the price of the UT210E.
So, following the crowd, the smart money is on the UT210E, and hacking it…
