1.

 

Insert the black meter pen into “COM” terminal and red one into 

 terminal. 

2.

 

Rotate the Range to “

” gear. Cross connect the test leads to the tested resistor. 

3.

 

When measuring the low resistance, please short-circuit the meter pens at first to test the wire 

resistance, and then deduct it from the actual resistance. 

Caution: 

1.

 

If “OL” is displayed on LCD, it indicates the tested resistance value has exceeded the present 

range limit, please select higher range to complete the measurement. When measuring the Resistor 
higher than 1M

, the instrument will take several seconds to make the reading stable. It is normal 

when measuring the high resistor. 

2.

 

When the input terminal is open circuit, it will display “OL”. 

3.

 

When measuring in-line resistor, be sure that the power is off and all capacitors are discharged 

completely.
