Measurement Procedure 

1.  Select the desired measuring range on the meter. If the resistance of the device is unknown, 

start with the highest range and work downward. 

2.  Clip the test leads onto the device under test. Note: When using the 4-wire/4 alligator clip 

test leads, it is recommended that the current test leads be outside of the potential test leads 

(as shown in the diagram below). 

3.  For a short test duration of 10 seconds, press the TEST R

P

 button for less than 2 seconds. 

This EnerSave™ feature can be used to conserve battery power. 

4.  For a long test duration of 60 seconds, press the TEST R

P

 button for more than 3 seconds. 

5.  During the test, the meter will intermittently beep. At the end of the test or if the test is 

stopped, “

HOLD

” will appear and the last reading will be “frozen” on the display.
