Safety

Beware when measuring voltages above 50V, and ensure the leaads are rated appropriately for the voltage.

Before connecting to a circuit, ensure that volts are being measured. If set to measure amps or ohms, then connecting to the wrong points could instantly damage the meter and circuit.

Digital Multimeters

There is a motley collection of unexciting handheld multimeters. They all have different limits, and be very cautious if you are measuring more than 50V.

Analogue Multimeters

We have three SEI Selectest Super 50 multimeters. These are similar to Avo 8s, are 20kohm/V (i.e. 50uA FSD) meters that can measure up to an unusually high 2.5kV. Before connecting them to a circuit, read the brief instructions on the back plate to see which terminals to use.

One of the ohmmeter ranges requires a small 15V (!) battery. It is doubtful we will bother to buy these.
