3. Setup
3.1 Battery Installation
The UT60S requires 1 Lithium Metal battery (included). To install or replace the battery:
- Ensure the multimeter is turned off and test leads are disconnected.
- Locate the battery compartment cover on the back of the device.
- Unscrew the retaining screws and carefully remove the cover.
- Insert the battery, observing the correct polarity (+/-) as indicated inside the compartment.
- Replace the battery cover and secure it with the screws.

3.2 Connecting Test Leads
Always connect the black test lead to the "COM" (common) jack. Connect the red test lead to the appropriate input jack based on the measurement you intend to perform (e.g., "VΩHz" for voltage/resistance/frequency, "mA" for milliampere current, "A" for ampere current).
4. Operating Instructions
Before operating, ensure you have read and understood all safety warnings. Select the correct function and range before connecting the test leads to the circuit.
4.1 Basic Measurements
- Voltage (AC/DC): Turn the function switch dial to the V~ (AC) or V- (DC) position. Connect the test leads in parallel to the circuit or component.
- Current (AC/DC): Turn the function switch dial to the A~ (AC) or A- (DC) position. Connect the multimeter in series with the circuit. Ensure the correct input jack (mA or A) is used.
- Resistance (Ω): Turn the function switch dial to the Ω position. Connect the test leads across the component.
- Continuity Test: Turn the function switch dial to the continuity position. The multimeter will beep if continuity is detected.
- Diode Test: Turn the function switch dial to the diode position. Connect the test leads across the diode.

Figure 6: The UT60S features a button-based design for easy AC/DC switching and quick measurements, facilitating one-handed operation.
4.2 Advanced Functions
- Non-Contact Voltage (NCV): Activate the NCV function and bring the top of the multimeter near an AC voltage source. The LED indicator and audible alarm will signal the presence of voltage.
- Backlight: Press the "Light" button to activate the display backlight for improved visibility in dimly lit environments.
- Data Hold: Press the "HOLD" button to freeze the current reading on the display. Press again to release.
- Relative Mode (RELΔ): Press the "RELΔ" button to store the current reading as a reference value. Subsequent measurements will be displayed as the difference from this reference.

5. Maintenance
5.1 General Care
- Keep the multimeter dry. If it gets wet, wipe it dry immediately.
- Use and store the multimeter in normal temperature environments. Extreme temperatures can shorten the life of electronic devices.
- Handle the multimeter gently and carefully. Dropping it can damage circuit boards and mechanical parts.
- Keep the multimeter away from dust and dirt, which can cause corrosion of electronic components.
- Wipe the multimeter with a damp cloth occasionally to keep it looking new. Do not use harsh chemicals, cleaning solvents, or strong detergents.
5.2 Battery Replacement
When the low battery indicator appears on the display, replace the battery as described in Section 3.1. Remove the battery if the multimeter will not be used for an extended period to prevent leakage.
6. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No display or dim display | Low battery; Multimeter off; Damaged display. | Replace battery; Turn on multimeter; Contact support. |
| Incorrect readings | Incorrect function/range selected; Poor test lead connection; Damaged test leads; Out of calibration. | Select correct function/range; Check connections; Replace test leads; Contact support for calibration. |
