Multimeters offer safe testing of circuits

TWO general purpose multimeters allow the safe testing of circuitry on all types of electrical equipment.

The CDM10 and CDM20 digital units, from Clarke Power Products, measure AC/DC volts, current and resistance, and can test diodes and transistors.

The base model, CDM10, has a 19-position rotary range selector, and is capable of measuring currents up to 10amps. Price is £13.

Also capable of measuring currents of up to 10amps, the higher spec CDM20 is fitted with a 30-position selector and an audible continuity test. Price is £25.

Both multimeters have automatic over-range and polarity indication, and are supplied with detachable probes and batteries (0181-986 8231).
