Operating Instructions

Always ensure the test leads are correctly inserted into the appropriate input terminals for the desired measurement.

1. DC Voltage Measurement

1. Insert the red test lead into the VΩHz%Temp terminal and the black test lead into the COM terminal.
2. Turn the rotary switch to the "V" position (DC Voltage).
3. Connect the test leads across the DC voltage source to be measured.
4. Read the DC voltage value on the LCD display.

2. AC Voltage Measurement

1. Insert the red test lead into the VΩHz%Temp terminal and the black test lead into the COM terminal.
2. Turn the rotary switch to the "V~" position (AC Voltage).
3. Connect the test leads across the AC voltage source to be measured.
4. Read the AC voltage value on the LCD display.

3. Current Measurement (DC/AC)

1. For currents up to 600mA, insert the red test lead into the mA FUSED terminal. For currents up to 10A, insert the red test lead into the 10A FUSED terminal. Insert the black test lead into the COM terminal.
2. Turn the rotary switch to the "mA" or "A" position. Use the FUNC button to switch between DC and AC current if necessary.
3. Disconnect power to the circuit. Open the circuit where current is to be measured.
4. Connect the multimeter in series with the circuit.
5. Apply power to the circuit and read the current value on the LCD display.
6. After measurement, disconnect power, remove the multimeter, and close the circuit.

4. Resistance Measurement

1. Insert the red test lead into the VΩHz%Temp terminal and the black test lead into the COM terminal.
2. Turn the rotary switch to the "Ω" position.
3. Ensure the circuit or component is de-energized before connecting the test leads across the component to be measured.

User Tips

• For stable readings, especially with capacitance, allow a few seconds for the measurement to settle.
• When measuring current, always start with the highest range and work your way down if the reading is too low, to prevent overloading the meter.
• Utilize the Data Hold function (H/★ button) to freeze the current reading on the display, which is useful in dimly lit areas or when taking measurements in awkward positions.
• The backlight (activated by pressing and holding H/★ button) significantly improves readability in low-light conditions.
• Remember to turn off the multimeter when not in use to conserve battery life.
