## Questions & Answers

**Q: What's the minimum DC current?**
A: This thing seems to be reasonable accurate down to 20ma, start getting under that threshold and it progressively gets worse. Not really worth the money. $125 meter for $350.  If you need to read current that low break the circuit and use a standard multimeter. Not to say it’s totally useless but it has its limits.

**Q: Is this just a rebranded version of the uni-t?**
A: Other answers are incorrect. This is a UNI-T UT213C. It's printed on the circuit board inside. UNI-T makes some great stuff now, I would recommend the UT216D instead, it's an updated version of this meter with a much nicer screen and a 600A range. Can be found on AliExpress for around the same price as this Extech

**Q: Will this read mV (millivolts)?**
A: Yes, this will read millivolts.

**Q: It measures temperature in C or F?**
A: Hello,Thank You for your interest in the MA445 clamp meter. The MA445 can measure temperature in both °F And °C.Measurement ranges are:-40° to 1832°F/-40° to 1000°C (1°F/°C)Best Regards

    Junk, do not buy
  

*by A***R on Reviewed in the United Kingdom on 27 February 2021*

Absolute junk, doesn't even register DC amps when using clamp, nothing at all, not even starter current. Complete waste of money.

### ⭐⭐⭐⭐⭐
