Earth Ground Resistance test

 

 

1.  Connect the 3 test leads to the meter (1) as follows: 

 

Green lead (2) to the 'E' terminal 

 

Yellow lead (3) to the 'P' terminal 

 

Red lead (4) to the 'C' terminal 

2.  Drive the Auxiliary Earth Bars P1 (6) & C1 (7) into the ground. Align the bars an equal distance 

apart to the existing Earth ground rod connection and in a straight line as shown in the diagram 
above.  
 
If the auxiliary bars are placed in close proximity to the ground stake, measurement 
inaccuracies will result.  
(Minimum distance between rods should be no less than 10 feet (3m). 

3.  Connect the alligator clip end of the test leads to the Earth bars and existing ground rod 

connection as shown above: 

 

Green lead (2) to the existing ground rod (5) 

 

Yellow lead (3) to Earth Bar P1 (6) 

 

Red lead (4) to the Earth Bar C1 (7) 

4.  Set the meter's function switch to the desired resistance range. (20, 200, 2000

). 

5.  Zero the range as described in the Zero adjustment procedure above. 

6.  Press the TEST button. . The “   “ icon will flash and the audible signal will sound. 
7.  Note the displayed reading.  
8.  If high resistance is detected, note the value and take appropriate steps to correct the ground 

connection if necessary. 

9.  Press to TEST key to end the test. 

10. Readings of “1”…….

 are typical when the test leads are not connected to the meter. 

 

HOLD Function 

The Hold function freezes the latest measurement reading on the LCD. 
1.  Press the HOLD key to freeze the reading on the LCD 
2.  Press the HOLD key again to exit the HOLD function. 
3.  The HOLD function does not retain measurement data if the meter is turned off. 

 

Backlight 

1. 

Press the “   “ key to turn on the backlight.

 

2. 

The backlight will turn off after approximately 15 seconds.
