1. Operation

2. Earth Voltage Testing: Turn the rotary switch to select EARTH VOLTAGE.

Connect the test leads to terminal V and E, and then connect to the

testing points. LCD display will display earth voltage value.

Voltage Measurement

0 -400V AC, 50/60 Hz

Note:Do not press the TEST button when measuring the earth voltage.

If the measuring value>10V, switch-off all related voltage equipments. Wait

until the earth voltage decrease, and then do it again. Otherwise, it may

influence the accuracy of earth resistance.

WARNING!

�

Ground voltage testing only work in terminal V and E, H and S connecting

cable must be separated. Otherwise, it will cause danger and damage the

Tester.

3. Ground Resistance Testing: Turn the rotary switch to 40Ω or 400Ω or

4000Ω range,press"TEST"button, LCD display will show earth resistance

value. Choose the appropriate range depending on the earth resistance

value for better accuracy.

Note: when H or S does not connect properly, or earth resistance is out

of range,or testing terminal open circuit,LCD display will show"- - - - ",
