This instrument can be used either as an ammeter or a voltmeter but is generally used as a wattmeter. The electrodynamic or dynamometer-type instrument is a moving-coil instrument but the magnetic field, in which the coil moves, is provided by two fixed coils rather than by permanent magnets (eg: PMMC instruments) You can use the original wire by hooking it to the positive terminal on the voltmeter, but you must also run a wire from the negative terminal to a ground source. If you wire it as it was originally, you will create a dead short. Play it safe, and use all-new 10 gauge wire when installing either a voltmeter or an ammeter Multimeter is an electronic instrument, which is used to measure voltage, current and resistance. This is called as AVO meter (ampere, voltage, ohm). We can. Since the coil obeys Ohm's law, the current through it is proportional to the potential difference across it; and since the deflection of the pointer is proportional to the current it is therefore also proportional to the potential difference. Thus the instrument can be used as a voltmeter, giving full-scale deflection for a potential difference of 0.1 volt, or 100 millivolts

The ammeter bezel plate required two new holes (for the small mounting screws) and some trimming for proper placement of the voltmeter in the bezel.
