5. Setup
5.1 Battery Installation
The multimeter requires batteries for operation. To install or replace batteries:
- Ensure the multimeter is turned OFF.
- Locate the battery compartment on the back of the device.
- Open the battery compartment cover.
- Insert the batteries, observing the correct polarity (+/-).
- Close the battery compartment cover securely.
5.2 Connecting Test Leads
For most measurements, connect the test leads as follows:
- Insert the black test lead into the COM (Common) input jack.
- Insert the red test lead into the INPUT jack.
6. Operating Instructions
This section details how to use the multimeter for various measurements.
6.1 General Operation
- Turn the rotary switch to the desired measurement function.
- If a function has multiple modes (e.g., AC/DC voltage), press the SEL button to cycle through them.
- Connect the test leads to the circuit or component under test.
- Read the measurement value on the display.
6.2 Voltage Measurement (AC/DC)
- Set the rotary switch to the “V” position.
- Press SEL to select AC (“ACV”) or DC (“DCV”) voltage.
- Connect the test leads in parallel to the circuit or component.
6.3 Current Measurement (AC/DC)
- Set the rotary switch to the “mA/A” position.
- Press SEL to select AC (“ACA”) or DC (“DCA”) current.
- Connect the multimeter in series with the circuit. Ensure the circuit is open before connecting the meter.
6.4 Resistance Measurement
- Set the rotary switch to the “Ω” position.
- Connect the test leads across the component. Ensure the component is de-energized.
6.5 Continuity Test
- Set the rotary switch to the “Ω” position.
- Press SEL until the continuity symbol (“♫”) appears.
- Connect the test leads across the circuit or component. A continuous beep indicates continuity.
6.6 Diode Test
- Set the rotary switch to the “Ω” position.
- Press SEL until the diode symbol (“→|”) appears.
- Connect the red lead to the anode and the black lead to the cathode of the diode.
6.7 Capacitance Measurement
- Set the rotary switch to the “Cap” position.
- Connect the test leads across the capacitor. Ensure the capacitor is discharged before testing.
6.8 Temperature Measurement
- Set the rotary switch to the “Temp” position.
- Connect the K-type thermocouple to the input jacks, observing polarity.
- Place the thermocouple tip on or in the object whose temperature is to be measured.

6.9 NCV (Non-Contact Voltage) Detection
- Press the V~Alert button.
- Move the top end of the multimeter (V~Alert sensor area) close to an AC voltage source. The meter will beep and the display will indicate the presence of AC voltage.
6.10 Live Wire Detection
- Set the rotary switch to the “Live” position.
- Insert the red test lead into the live wire socket. The display will indicate if the wire is live.
6.11 Frequency (Hz) Measurement
- Set the rotary switch to a voltage or current function.
- Press the Hz button. The meter will display the frequency of the measured signal.
6.12 Data Hold and Backlight
- Data Hold: Press the HOLD button briefly to freeze the current reading on the display. Press again to release.
- Backlight: Long press the HOLD button to turn the display backlight ON or OFF.
7. Maintenance
7.1 Cleaning
Wipe the case with a damp cloth and mild detergent. Do not use abrasives or solvents. Keep the input terminals free from dirt and moisture.
7.2 Battery Replacement
When the low battery indicator appears on the display, replace the batteries immediately to ensure accurate measurements. Refer to section 5.1 for battery installation instructions.
7.3 Storage
