Do not apply any voltage or current to the measuring terminals.

In the case of high resistance measurement, readings may be 
unstable due to external inductive influence.

CAUTION

WARNING

3) Measuring procedure

Connect the red plug of the test lead to 

 measuring terminal and 

the black one to the COM terminal.

Set the function selector to 

.

Press the SELECT button to select a function you want to perform.

Apply the test pins (Red and Black) to the object to measure.

Read the display.
