Battery
1-3 Front Panel
Refer to Figure 1 and the following numbered steps to familiarize yourself with the meter’s front panel
controls and connectors.
1. Digital Display —The digital display has a 3 3/4 digit LCD readout (maximum reading 3999) plus auto polarity,
decimal point, , AC, DC, and unit annunciators.
2. Input Terminal — The black test lead is always connected to the “COM” input jack and the red test lead is always
connected to the “V Ω” input jack when measuring voltage or resistance.
* COM input terminal : Reference input connector.
* V Ωinput terminal : Positive input connector.

3. Function Switch —Rotary switch is used to select Hz, V, V, Ω, A, Afunction.
4. Trigger — Press the lever to open the transformer jaws. When the pressure on the lever is released, the jaws will
close again.
5. Transformer Jaws — Designed to pick up the current flowing through the conductor.
6. Hand Guard — Designed to protect user for safety.
7. PEAK HOLD SWITCH — To hold the peak measured positive value. For negative value zero is displayed.
8. DCA ZERO SWITCH — Auto compensate the residual magnetism by pressing this key (for A only)
