1. LCD display, 1999digits
2. Buttons
i. Hold: To hold the current reading, press this button and you will see "H" on the display,
press again to cancel.
ii. Display Backlight: To turn on the display light.
3. Rotary switch: To change mode or range.
4. V/Ω/mA: Input terminal for Voltage resistance, current (mA) diode, continuity measurements.
5. COM: Common Terminal for all Measurements.
6. 10A: Input terminal for related current measurements.
(1) Measure AC/ DC voltage
1. Insert the red test lead to the "VΩmA" terminal, and the black test lead to the "COM" terminal;
2. Turn the rotary switch to the DC voltage mode, or the AC voltage mode, choose the suitable
range if can't sure, choose the highest range.
3. Connect the probes to the correct test points of the circuit to measure the voltage;
4. Read the measured voltage on the display.
(2) Measure DC current
1. For current less than 200mA, insert the red test lead to the "VΩmA" terminal, if current is more
than 200mA, insert the red test lead into "10A" terminal, and the black test lead to the "COM"
terminal.
2. Turn the rotary switch to the DC current related Mode.
3. Break the circuit path to be measured. Then connect the test leads across the break and apply
power.
4. Read the measured current on the display
Caution:
a. Do not measure voltage exceeding the MAX value as indicated on the panel.
b. Do not touch the high voltage circuits during measurements.
Caution:
a. Do not measure current that exceeds the MAX value as indicated in the specifications;
b. Do not input voltage exceeds 36V DC or 25V AC when you are at the setting of measuring current.
