2. Safety Information
WARNING: To avoid electric shock or personal injury, read, understand, and follow all safety information and instructions before using this multimeter. Keep this manual for future reference.
- Always ensure the multimeter is in good working condition before use. Inspect test leads for damage.
- Do not apply more than the rated voltage, as marked on the meter, between the terminals or between any terminal and ground.
- Use caution when working with voltages above 30V AC RMS, 42V peak, or 60V DC. These voltages pose a shock hazard.
- Always disconnect the circuit power and discharge all high-voltage capacitors before testing resistance, continuity, or diodes.
- Do not operate the meter with the case open or the battery cover removed.
- Replace batteries immediately when the low battery indicator appears to ensure accurate readings.
- This multimeter is rated for CAT III 600V. Do not use it in environments exceeding this rating.

5. Setup
5.1 Battery Installation
The multimeter requires three (3) 1.5V AAA batteries for operation. To install or replace batteries:
- Ensure the multimeter is turned OFF.
- Locate the battery compartment on the back of the meter (refer to Figure 4.3).
- Use a screwdriver to loosen the screw securing the battery cover.
- Remove the battery cover.
- Insert three new 1.5V AAA batteries, observing the correct polarity (+/-) as indicated inside the compartment.
- Replace the battery cover and tighten the screw securely.
5.2 Connecting Test Leads
Always connect the black test lead to the "COM" (Common) input jack. Connect the red test lead to the "VΩ" input jack for voltage, resistance, continuity, and diode measurements. Ensure connections are firm.

6. Operating Instructions
This section details how to perform various measurements using the 61-327 Multimeter.
6.1 Measuring AC/DC Voltage
- Turn the rotary switch to the desired AC Voltage (V~) or DC Voltage (V=) range. Select a range higher than the expected voltage.
- Connect the black test lead to the "COM" jack and the red test lead to the "VΩ" jack.
- Connect the test probes in parallel to the circuit or component you wish to measure.
- Read the voltage value on the display.
6.2 Measuring Resistance (Ω)
- WARNING: Ensure the circuit is de-energized and all capacitors are discharged before measuring resistance.
- Turn the rotary switch to the desired Resistance (Ω) range.
- Connect the black test lead to the "COM" jack and the red test lead to the "VΩ" jack.
- Connect the test probes across the component where resistance is to be measured.
- Read the resistance value on the display.
6.3 Continuity Test
- WARNING: Ensure the circuit is de-energized before performing a continuity test.
- Turn the rotary switch to the Continuity (•))) position.
- Connect the black test lead to the "COM" jack and the red test lead to the "VΩ" jack.
- Touch the test probes to the two points you want to check for continuity.
- An audible tone indicates continuity (low resistance). The display will show the resistance value.
6.4 Diode Test
- WARNING: Ensure the circuit is de-energized before performing a diode test.
- Turn the rotary switch to the Diode (→|) position.
- Connect the black test lead to the "COM" jack and the red test lead to the "VΩ" jack.
- Connect the red test probe to the anode and the black test probe to the cathode of the diode.
- The display will show the forward voltage drop. Reverse the probes; the display should show "OL" (Open Loop) for a good diode.
6.5 Battery Test (1.5V / 9V)
- Turn the rotary switch to the 1.5V or 9V battery test position.
- Connect the black test lead to the "COM" jack and the red test lead to the "VΩ" jack.
- Connect the red test probe to the positive terminal of the battery and the black test probe to the negative terminal.
- Read the battery voltage on the display.
6.6 Non-Contact Voltage (NCV) Sensing
The NCV function allows for detection of AC voltage without direct contact with conductors.
- Turn the rotary switch to the NCV position.
- Move the top tip of the multimeter near the conductor or outlet to be tested.
- The meter will emit an audible tone and an illuminated red LED will flash when AC voltage is detected. The display may show "EF" or similar indication.

6.7 Using the HOLD Function
Press the "HOLD" button to freeze the current reading on the display. Press it again to release the hold and resume live readings.
6.8 Using the Backlight
Press the backlight button (light bulb icon) to illuminate the display for better visibility in dark conditions. Press it again to turn off the backlight.
7. Maintenance
7.1 Cleaning
Wipe the meter with a damp cloth and mild detergent. Do not use abrasives or solvents. Ensure the meter is completely dry before use.
7.2 Battery Replacement
Refer to Section 5.1 for instructions on battery installation and replacement. Always replace all three AAA batteries at the same time.
7.3 Test Lead Inspection

8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Meter does not power on. | Dead or incorrectly installed batteries. | Check battery polarity; replace batteries (refer to Section 5.1). |
| "OL" (Overload) displayed. | Measurement exceeds selected range or open circuit. | Select a higher range or check for an open circuit in the component/wiring. |
| Inaccurate readings. | Low battery, incorrect range selection, or damaged test leads. | Replace batteries, select appropriate range, inspect and replace test leads if damaged. |
| No continuity tone. | Open circuit or high resistance. | Verify the circuit is closed; check for breaks in wiring or components. |
