Tools and Hardware Reviews of Extech EX450 True RMS Autoranging Multimeter with Infrared Thermometer
Customer Review: Not so Accurate turn-off meter
Summary: 1 Stars
The Extech is more than annoying with its 15 min auto turn-off, it is dangerous when working on 440V equipment and I really need to know if a given circuit is alive or not. I use a non-contact Fluke tester to back me up, but still I also need to monitor voltage for longer than 15 frigging minutes. Also, the voltage readings lie, the DC voltage will read 15V when it is really 13.8 via two other meters, but other times it will read correctly, etc. Just not a reliable or good meter. Also don't like its HOLD feature which tends to get pushed and then it stays on whatever voltage was there which may not be the current voltage. I am looking for a better meter without such nasty quirks. I even use a little $4 meter for some things now, as it is more reliable that this POS meter.
