3. For measuring DC voltage , if L2 and L1 is connected respectively to the positive and negative pole
of the object to be measured, LCD displays the voltage, meanwhile LCD displays «+» «VDC» and, on
the contrary, LCD displays «-» «VDC». If need to judge the positive and negative pole of the object to be
measured, connect two test pens to the object to be measured randomly, the illuminating positive pole LCD
«+» on tester means the terminal connecting to L2 is the positive and the other connecting to L1 is the
negative.
4. For measuring AC voltage, two test pens may be randomly connected to two ends of the object to be
measured, LCD displays «VAC» while and corresponding voltage value.
Note: For measuring AC voltage, Land R phase inversion indication Land R symbol would be illuminated, it
means phase indication is unstable, L symbol or R symbol is illuminated, and even Land R symbol would be
illuminated alternatively; L and R symbol would not provide correct and stable indication unless measuring
three phase power system.

5. Continuity test

To confirm if the conductor to be measured is electrified, voltage measurement method may be adopted
to measure the voltage at both ends of the conductor by using two test pens. Connect two test pens to the
both ends of the object to be measured, if the resistance falls within 0- 100kΩ, or continuity symbol «·•>)
« would be illuminated, accompanied by continuous beeping buzzer; and if resistance falls within 100kΩ
- 150kΩ, continuity symbol «·1>) « may or may not be illuminated and buzzer may or may not beep; if
resistance is >150kΩ, continuity symbol «·•>) « may not be illuminated and buzzer would not beep. Before
any test, be sure the object to be measured is not electrified.
6. Rotation test (three-phase AC phase indication)
The measurement must be conducted in accordance with the safety test regulations specified in item 3.
L and R symbol indication is applicable for rotation test and the test is only applicable for three-phase AC
system.
1. Three-phase voltage test range: 57V- 400V (50Hz- 60Hz);
2. Hold the main body of tester (with finger holding handle), as shown in the following figure, connect test
pen L2 to any phase and L1 to any of remaining two phases.
3. R or L would be illuminated, and after connecting a test pen to another phase, another L or R would be
illuminated.
4. L or R would be illuminated accordingly when the position of two test pens are exchanged.
5. LCD displays corresponding voltage value, the indicated or displayed voltage should be phase voltage
against earth but three-phase voltage.
