Hi,
I recently got an Amprobe AM240 multimeter and thought I'd share my thoughts on it here as it seems to be targeted as a meter for hobbyists.
Martin you may want to review it at some point but I'd say don't spend precious money buying one!
The AM240 is the same as the AM220 except that it comes with a temperature probe.
Good points:
- good accuracy. Its readings closely match what my trusted Fluke 87 gives
Bad points:
- gives a deafening beep whenever you press any of the buttons. Very annoying after a while.
- unbelieveably slow continuity buzzer. Shockingly bad. I'd estimate the response time to be approaching half a second. Useless.
- poor backlight. Activating the backlight requires pressing the Hold button for 2 seconds. Then it goes off after 10 seconds. Useless.
- back of case is not rubberized, so it slides around if lying to on its back.
- the 3 connectors left to right are: Volts/Ohms/mA , Common, 10A . Why the hell did they decide to be the only multimeter which has the 10A terminal to the right?!! It's only a matter of time before I try to take a voltage reading with the leads connected to the 10A terminal.
- probes are mediocre quality and blunt, with only 2mm exposed metal at the tip.
- poor ergonomics in that it's very hard to operate the meter with one hand.
- temperature probe is very bulky and is only really suitable for measuring liquids
Verdict: very disappointing, expected a lot more. I also have an Extech EX330 which is in the same price range and supposedly the same class, but beats the Amprobe in every one of the points above and is a first class little meter.
Hope this might be useful to someone.
Billy.
