Select the fitting range on the tester in order to read precise

measurement from each range on the tester.

For example, if the tester has a 200Ω, 20Ω and 2Ω ranges.

Use the 200Ω range to measure “10Ω”, the 20Ω to measure “2Ω”

and the 2Ω to measure “0.5Ω”.

Common Problems

Solution

Reading unstable

Check connections are clean and

tight in the sockets.

Reading high

Poor leads will give a high zero.

Check tester is zeroed correctly with

leads shorted together.

Tester reads over range

The test leads are open circuit. Note

some test leads are fused and some

use special connectors. Check leads

are OK.

CHECKING FOR THE AC VOLTAGE MEASUREMENT

FUNCTION

Some multi-function, insulation and installation testers can

measure AC voltage.

WARNING: MAIN AC OUTPUT VOLTAGE IS PRESENT

DURING THIS TEST AND WATCH OUT FOR AVOIDING

ELECTRIC SHOCK.
