1. Set the Dial to V range.
2. Press and hold RANGE and MIN/MAX button to enter Phase rotation mode.
Press RANGE button to enter Voltage Unbalance test mode.
Upper display indicates "V1V2".
Press Min/Max button to enter Testing standby mode.
"V1V2" will blink on display.
NOTE: Steps 3 - 4 needs completed within 30 seconds. If not, the display will
indicate "oVEr" and the meter will finish the testing.
3. Connect test leads to any two lines (V1 – V2) of the 3-Phase voltage lines.
A beep indicates stable voltage is captured, and the Upper display shows
"V1V3".
4. Remove Red Test lead from the voltage line.
A beep and "V1V3" blinking on display will indicate test is ready.
Connect the Red test lead to the third voltage line (V1 – V3).
5. A beep indicates test is complete.
Upper display will indicate test result (PASS or FAIL).
Lower display will indicate the percentage:
PASS % unbalance <2%
FAIL % unbalance > 2%
% V unbalance = (Max deviation from Avg Voltages/Avg Voltage) x 100.
1. Set the Dial to A range.
2. Press and hold RANGE and MIN/MAX to enter Current Unbalance test mode
Lower Display will indicate "A".
3. Press Min/Max button to enter testing standby mode.
"-A1-" will blink on display.
NOTE: Each of steps 4 – 6 needs to be conducted within 30 seconds. If not,
the display will indicate "oVEr" and the meter will finish the testing.
4. Clamp the jaw around current line (A1).
A beep indicates stable current is captured, and Lower display shows "-A2-".
Remove clamp jaw from current line.
A beep and "-A2-" blinking on display will indicate test is ready.
5. Clamp the jaw around current line (A2).
A beep indicates stable current is captured, and the Lower display shows
"-A3-".
Remove clamp jaw from the current line.
A beep and "-A3-" blinking on display will indicate test is ready.
6. Clamp the jaw around current line (A3).
A beep indicates stable current is captured.
Upper display indicates test results (PASS or FAIL).
Lower display will indicate the percentage:
PASS % unbalance <10%
FAIL % unbalance > 10%
% I unbalance = (Max deviation from Avg Currents/Avg Currents) x 100.
