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

-We have three SEI Selectest Super 50 multimeters, which 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. +We have three SEI Selectest Super 50 multimeters.

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