(1) Select the 20Ω range by rotating the FUNCTION

switch and connect the test leads to the

instrument. Short the tips of the test leads. Press

and hold down the TEST button by twisting it

clockwise.

The display will show the resistance of the

test leads. Adjust the Ω Null control to set the

reading to zero.

(2) Connect the test leads to the circuit under test.

Ensure the circuit is not live by checking that

the live circuit indicator does not light. Read the

value of resistance from the LCD.

● AC voltage test :

Set the FUNCTION switch to ACV. Connect test

leads to circuit being measured. Press TEST button

and read the value of voltage from the LCD.
