2. Safety Information
WARNING: To avoid electric shock or personal injury, read and understand all safety information before using this product.
- Always ensure the multimeter is in the correct measurement mode before connecting test leads to a circuit.
- Do not apply voltage or current that exceeds the maximum rated values for the multimeter.
- Inspect test leads for damage before each use. Do not use if insulation is compromised.
- Do not use the multimeter if it appears damaged or if the battery cover is not properly closed.
- Exercise extreme caution when working with voltages above 30V AC RMS, 42V peak, or 60V DC. These voltages pose a shock hazard.
- Replace batteries immediately when the low battery indicator appears to ensure accurate readings.
- Do not operate the multimeter in explosive gas, vapor, or dusty environments.
- Always disconnect power to the circuit and discharge all high-voltage capacitors before measuring resistance, continuity, diodes, or capacitance.

5. Setup
5.1 Battery Installation
The ADMS9 Multimeter is powered by internal batteries (typically AAA, refer to the battery compartment for specifics). To install or replace batteries:
- Ensure the multimeter is powered off and disconnect all test leads.
- Locate the battery compartment on the back of the device.
- Use a screwdriver to open the battery compartment cover.
- Insert new batteries, observing the correct polarity (+/-).
- Replace the battery compartment cover and secure it with the screw.
Note: A common issue reported is battery drain when not in use. It is recommended to remove batteries if the device will not be used for extended periods.
5.2 Connecting Test Leads
Connect the test leads to the multimeter before taking any measurements:
- Insert the black test lead into the "COM" (Common) input jack.
- Insert the red test lead into the "VΩHz" input jack for voltage, resistance, frequency, capacitance, and diode measurements.
6. Operating Instructions
6.1 Power On/Off and Auto Mode
- Press the Power Switch button (1) to turn the multimeter on. The device will typically start in Auto mode, automatically detecting the measurement type (voltage, resistance, continuity).
- Press and hold the Power Switch button to turn the multimeter off.
6.2 AC Voltage Test
To measure AC voltage and frequency:
- Ensure the multimeter is in Auto mode or manually select AC voltage if available.
- Connect the red test lead to the live (hot) terminal and the black test lead to the neutral or ground terminal of the AC source.
- Read the AC voltage and frequency values displayed on the screen.

6.3 DC Voltage Test
To measure DC voltage:
- Ensure the multimeter is in Auto mode or manually select DC voltage if available.
- Connect the red test lead to the positive (+) terminal and the black test lead to the negative (-) terminal of the DC source.
- Read the DC voltage value displayed on the screen.

6.4 Capacitance Test
To measure capacitance:
- Ensure the circuit is de-energized and any capacitors are fully discharged before testing.
- Press the Capacitance Button (5) to switch to capacitance mode.
- Connect the test leads across the capacitor terminals.
- Read the capacitance value displayed on the screen.

6.5 Resistance, Diode, and Continuity Test
In Auto mode, the multimeter can automatically detect and measure resistance, diode forward voltage drop, or continuity.
- Resistance: Connect test leads across the component. The display will show resistance in Ohms (Ω).
- Diode: Connect test leads across the diode. The display will show the forward voltage drop. Reverse the leads to check for open circuit.
- Continuity: Connect test leads across the circuit. A low resistance (typically <50Ω) will trigger an audible beep, indicating continuity.
WARNING: Ensure the circuit is de-energized before performing resistance, diode, or continuity tests.
6.6 V-Alert (NCV) and Live Wire Check
These features allow for non-contact detection of AC voltage, enhancing safety.
- V-Alert (NCV): Press the V-Alert or Live Wire Check Button (4). Place the V-Alert sensor area (3) near an AC voltage source. The multimeter will beep and the analog bar will indicate the strength of the detected field.
- Live Wire Check: This function helps identify live wires. Follow the device's specific instructions for this mode, usually involving placing one test lead into a socket and using the NCV sensor.
6.7 Flashlight
Press the Flashlight Switch (6) to turn the built-in LED flashlight on or off, useful for illuminating dark work areas.
7. Maintenance
7.1 Cleaning
Wipe the case with a damp cloth and mild detergent. Do not use abrasives or solvents. Ensure the device is completely dry before use.
7.2 Battery Replacement
When the low battery indicator appears on the display, replace the batteries as described in the "Battery Installation" section (5.1). Always use the specified battery type.
8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Multimeter does not power on. | Dead or incorrectly installed batteries. | Check battery polarity and replace batteries if necessary. |
| Inaccurate readings. | Low battery; incorrect mode selection; damaged test leads. | Replace batteries; ensure correct measurement mode; inspect and replace test leads if damaged. |
| "OL" or "OVER" displayed. | Measurement exceeds the selected range or maximum input. | In Auto mode, this indicates an out-of-range value. Ensure the input is within the device's specifications. |
| Batteries drain quickly when not in use. | Known characteristic for some units. | Remove batteries if the device will not be used for extended periods. |
