1-3 Front Panel
Refer to Figure 1 and the following numbered steps to familiarise yourself with the meter's front panel controls and
connectors.
1. Digital Display —The digital display has a 3200 counts LCD readout with 65 segments analog bar graph, auto
polarity, decimal point, <, =, DC, AC, ;, I, and Unit annunciators.
2. Rotary Switch —Selects the desired function and range.
3. COM Input Terminal —Ground input connector.
4. VΩInput Terminal —Positive input connector for Volts, Ohms and Diode measurements.

5
5. µA mA Input Terminal —Positive input connector for current measurements. (up to 300mA).
6. A Input Terminal —Positive input connector for current measurements. (up to 10A)
7. Function Switch (Blue) —Press the switch to measure AC Current or DC Current in the current mode, or to
measure continuity or diode check in ;/9mode.
8. Reset Switch - The meter can be turned back on by pushing "RESET" key switch.
9. Hold Switch - This switch is used to hold measured values for all functions. When pressed the "=" annunciator
is displayed. Conversions are made but the display is not updated.
10. Range Switch (Manual Range) –The "Range" switch is pressed to select manual ranging and to change
ranges. When the "Range" switch is pressed once, the "RANGE" annunciator on the LCD disappears. Press the
"Range" switch to select the appropriate range to be used. Press the "Range" switch and hold for 2 seconds to
return to Auto-ranging.
