4.0 out of 5 stars Power saver too quick and not well thought out, April 19, 2007

By	Benbrilling (Santa Cruz, CA USA) - See all my reviews

The meter seems to work fine in most things I've tried in the week I've had it, but one thing really annoys me. The power saver turns it off only 15 minutes after you turn it on. It would be acceptable if it turned itself off 15 minutes after the last electrical activity, but no, it is 15 minutes after you turn it on. I often need to make measurements over a period of time longer than that and really don't appreciate it shutting down without warning in the middle of a measurement. I would be much happier with a shorter battery life and a longer time before shutdown. It's only an inexpensive standard 9V battery.

1.0 out of 5 stars Not so Accurate turn-off meter, January 28, 2008

By	George R. Edge "gedgetips" (Sacramento, CA USA) - See all my reviews (REAL NAME)

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.
