Test Preparation and Setup
1. Connect the test leads to the meter as follows:
•
Green lead to the 'E' terminal
•
Yellow lead to the 'P' terminal
•
Red lead to the 'C' terminal
2. Drive the Auxiliary Earth Bars C1 & P1 (included) into the ground. Align the bars
equidistant to the existing Earth ground connection and in a straight line as shown in
the diagram above.
3. Ensure that the bars are between 17 and 33 ft (5 and 10 meters) apart. If the auxiliary
bars are placed in close proximity to the ground stake, measurement inaccuracies will
result.
4. Connect the clamp ends of the test leads to the Earth bars and existing ground
connection spike as shown above.
Earth Voltage Test
1. Set the meter's function switch to the ACV position.
2. Press the PUSH-ON button to perform a single, momentary test.
3. Press the PUSH-ON and TIMER ON buttons simultaneously to begin a 3-minute test.
The 3-minute test automatically shuts down after 3 minutes. Press the Timer OFF
button to end an automatic test at any time.
4. The front panel test status LED will light if the test is operating correctly. If the LED
does not light check for problems such as open circuits or overload conditions.
5. Note the LCD reading.
6. Confirm that the voltage measurement is less than 10V AC; otherwise accurate Earth
resistance measurements cannot be made. If voltage is present (higher than 10V AC),
the source of the voltage must be found and corrected before testing can continue.
