Amprobe PM55A Digital Multimeter


Great on the go

5.0

Great little pocket meter. Pros: it has everything you might think of: AC and DC Volts, both HiZ (“normal”) and LoZ modes (to remove stray voltages, apply a load to check batteries or discharge capacitors), continuity check (latched, responsive, loud enough, with a nice representation of an ON/OFF switch on the display – but see “cons”), resistance, capacitance (not to be trusted for values under 1 nF, as in most other multimeters), AC and DC current (upper limit: 2 mA), diode check (no LEDs), frequency (the signal has to pass through 0, no duty cycle). It also sports a very sensitive electric field (EF) detector, which would tell you if a mains wire is energized without touching it. Tip: in EF mode, you can figure which wire is “hot” and which wire is “neutral” by touching it with one of the probes – the hot wire gives a stronger signal (the black probe works better, make sure you don’t touch the loose probe when you do so). The probes are nice, with notched tips and flexible wires. It comes with a small, high-quality carrying pouch in which everything fits nicely. As any Amprobe, it can be trusted for safety when probing mains voltages (it is also UL certified). Cons: the menu (selecting what you want to measure) is quite awkward and it takes quite a while to circle through the options by pressing the middle button until you get where you want to be. You’ll eventually get there, if you happen to be on the right position of the rotary switch (good luck figuring which position would that be for capacitance mode by just looking at the dial). Luckily, there is a very helpful menu chart on the back of the meter and there is also a lazy mode (they call it “Auto”), in which the meter figures for you what you want to measure (you just have to wait a little bit longer – not a big problem if you’re lazy in the first place). Also, it beeps continuously when measuring low ohm resistors (tens), as if you’d check continuity. I’d rather have the meter display the ohm value when checking for continuity (in continuity mode, instead of displaying a rough representation of an ON/OFF switch) and keep silent when measuring ohms, in resistance mode. Overall – not a replacement for a “real” meter, but highly recommended when needed on the go. Great addition to your messenger bag.
