Student Dual Amp/Volt Meter. This dual purpose student bench meter offers an analogue quadruple range, making it very versatile. A slide selector for amps/volts automically selects internal shunting, indicating whether on amps or volts reading and secures the input sockets from the possibility of incorrect connection. Input is made via a dual 4mm or terminal type connection and zeroing is achieved by the screw adjustment on the front of the meter.
