Measuring ACV/DCV : Auto sense function

Auto sense mode: The meter displays ACV or DCV whichever is higher (>1V).
If the measured voltage is above 660Vac/dc, ” > 660Vac/dc ” will appear on the display.

-Insulation-Tester-and-Multimeter-User-Manual_2.png)WARNING**

When connecting the test leads to the DUT (Device Under Test) connect the common test leads before connecting the live leads; When removing the test leads, remove the test live leads before removing the common test leads.
Don’t apply more than AC/DC 600V between the V-COM terminals.

Measuring Earth-Bond Resistance (Continuity)

Before starting the test :

• * The circuit under test must be completely de-energized.

  • Check the fuse is See the chapter “ Testing the

fuse ”.

• Short the test leads before measurement, and press the Function button to zero the wire resistance of probe. If the wire resistance is <10Ω, the resistance offset value will be saved, and the “->0<-” symbol will be displayed onLock mode :

Press the Lock button to enter the Lock Mode.
Then press the TEST button to start the test. The test voltage will continue to be applied until the TEST/LOCK button is pressed again.

2. The meter displays the ” ＞ ” symbol and the maximum resistance for the range when measured resistance is higher than the maximum display

Measuring Insulation Resistance

1. Before starting the test :
   The circuit under test must be completely de-energized.
   If the voltage detected is above 30V, “>30V” will appear on the display. In this condition, the test is inhibited.

2. Press the Function button to display insulation resistance or
   Leakage current during the test or when the test stops.

3. Lock mode: Press the Lock button to enter the Lock Mode. Then press TEST button >1sec to start the test. The test voltage will continue to be applied until the TEST/LOCK button is pressed

4. Stop the output test voltage before removing the test leads (to enable the tester to discharge capacitive circuits).
   If the screen displays volts, wait until it reaches zero.

5. The meter displays the ” ＞ ” symbol and the maximum resistance for the range when measured resistance is higher than the maximum display

Using the Compare function

Before starting the Insulation Resistance test, select the comparative value in Setup mode: 0.5MΩ, 10MΩ, 20MΩ, 50MΩ, 100MΩ, 200MΩ, 500MΩ, 1000MΩ.
Before starting the Earth-Bond Resistance test, select the comparative value in Setup mode: 0.5Ω, 1Ω, 2Ω, 3Ω, 4Ω, 5Ω, 10Ω, 20Ω, 30Ω, 40Ω.
If the measured value is better than the selected compare value, the Pass indicator will be green, otherwise it is red.

Auto Power Off (Battery Saver)

Restore power by switching rotator or by pressing any button.

Battery and Fuse Replacement

Refer to the following figure to replace fuse and the batteries :

Caution

• Use only a fuse with the amperage, interrupt, voltage, andspeed rating specified.
• Fuse rating : Fast, 315mA, 1000V, at least 10kA InterruptRating.
• Replace battery as soon as low battery indicator blinks /appears to avoid false reading.
