WARNING 

 

TO AVOID ELECTRIC SHOCK HAZARD, OR DAMAGE TO THE METER, DO NOT ATTEMPT TO MEASURE  
VOLTAGES THAT MIGHT EXCEED 600 V d.c. OR 600 V a.c.rms.  DO NOT APPLY MORE THAN 600V d.c. OR  
600V a.c. RMS BETWEEN THE COMMON INPUT TERMINAL AND EARTH GROUND. 
 

3-3 Resistance Measurement 

1. Connect the red test lead to the "V

Ω

9

" terminal and the black test lead to the "COM" terminal. 

2. Set the rotary function switch to the "

Ω

" position . 

3. For correct reading, ensure that there is no voltage present across the device being tested. 
4. Connect the test leads across the resistor to be measured.  In order to ensure the best accuracy in measurement  
     of low resistance, short the test leads before measurement and note the test lead resistance. It is necessary to  
     subtract the resistance of the test leads from the displayed reading.
