5. Setup
5.1 Battery Installation
- Ensure the multimeter is turned off and disconnect any test leads.
- Locate the battery compartment cover on the back of the device.
- Use a screwdriver to remove the screw securing the battery cover.
- Insert two 1.5V AAA batteries, observing the correct polarity (+/-) as indicated inside the compartment.
- Replace the battery compartment cover and secure it with the screw.

5.2 Connecting Test Leads
- Insert the black test lead into the 'COM' (common) jack.
- For most voltage, resistance, and small current (mA) measurements, insert the red test lead into the 'VΩmA' jack.
- For large current (10A) measurements, insert the red test lead into the '10A' jack.

6. Operating Instructions
Before taking any measurement, ensure the test leads are correctly connected and the rotary switch is set to the desired function and range.

6.1 Measuring DC Voltage (V–)
- Set the rotary switch to the desired DC Voltage (V–) range. If the voltage is unknown, start with the highest range and decrease as needed.
- Connect the red test lead to the positive (+) side of the circuit and the black test lead to the negative (-) side.
- Read the voltage value on the display.
6.2 Measuring AC Voltage (V∼)
- Set the rotary switch to the desired AC Voltage (V∼) range.
- Connect the test leads across the AC voltage source.
- Read the voltage value on the display.
6.3 Measuring DC Current (A–)
- Important: To measure current, the multimeter must be connected in series with the circuit.
- Set the rotary switch to the appropriate DC Current (A–) range (e.g., mA or 10A).
- If measuring 10A, move the red test lead to the '10A' jack. For mA, keep it in 'VΩmA'.
- Open the circuit where you want to measure current. Connect the multimeter in series, ensuring the current flows through the multimeter.
- Read the current value on the display.
6.4 Measuring Resistance (Ω)
- Ensure the circuit is de-energized before measuring resistance.
- Set the rotary switch to the desired Resistance (Ω) range.
- Connect the test leads across the component or circuit segment to be measured.
- Read the resistance value on the display.
6.5 Backlight Function
Press the backlight button (often indicated by a light bulb icon) to illuminate the display for better visibility in low-light conditions. Press it again to turn off the backlight.
6.6 Data Hold Function
Press the 'HOLD' button to freeze the current reading on the display. Press it again to release the hold function and resume live readings.

7. Maintenance
7.1 Cleaning
Wipe the multimeter casing with a damp cloth. Do not use abrasive cleaners or solvents. Ensure the device is dry before use.
7.2 Battery Replacement
When the battery indicator appears on the display, replace the batteries as described in the 'Battery Installation' section (5.1).
7.3 Fuse Replacement
If the current measurement function stops working, the fuse may need replacement. Refer to the warning label on the back of the device for the correct fuse rating (e.g., F200mA/250V). Disconnect all test leads and turn off the multimeter before opening the case to replace the fuse.
7.4 Storage
Store the multimeter in a cool, dry place away from direct sunlight and extreme temperatures. If storing for extended periods, remove the batteries to prevent leakage.
8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Display is blank or dim | Low batteries or no batteries installed. | Replace batteries (refer to section 5.1). |
| No reading for current measurement | Blown fuse or incorrect test lead connection. | Check and replace fuse (refer to section 7.3). Ensure red lead is in '10A' or 'VΩmA' jack as appropriate and connected in series. |
| Incorrect readings | Incorrect function/range selected or poor test lead contact. | Verify function switch setting and range. Ensure test leads make firm contact with the circuit. |
| Multimeter automatically shuts off | Automatic shutdown feature activated. | This is normal behavior after 15 minutes of inactivity. Turn the rotary switch to 'OFF' and then back to the desired function to restart. |
