4. Setup

4.1 Battery Installation

The PEAKMETER PM8231 requires 2 x 1.5V AAA batteries for operation. The battery compartment is located on the back of the device.

1. Ensure the multimeter is turned off and disconnect all test leads from the device and any circuits.
2. Locate the battery compartment cover on the rear of the multimeter (refer to Figure 3).
3. Use a screwdriver to open the battery compartment cover.
4. Insert two 1.5V AAA batteries, observing the correct polarity (+/-) as indicated inside the compartment.
5. Replace the battery compartment cover and secure it with the screw.

4.2 Connecting Test Leads

Connect the red test lead to the "VΩ" input jack and the black test lead to the "COM" (common) input jack. Ensure a secure connection before performing any measurements.

5. Operating Instructions

The PM8231 is a full automatic portable multi-meter. When powered on, it can directly measure, avoiding complexity and gear shifting errors.

5.1 Power On/Off

Press the power button (usually marked with a circle and a vertical line) to turn the multimeter on. The device features an "Auto Power Off" function to conserve battery life.

5.2 DC Voltage Measurement

1. Turn on the multimeter. The device will automatically enter auto-ranging mode.
2. Connect the red test lead to the positive (+) side of the DC voltage source and the black test lead to the negative (-) side.
3. Read the DC voltage value displayed on the screen.

5.3 AC Voltage Measurement

1. Turn on the multimeter.
2. Connect the test leads across the AC voltage source. Polarity is not critical for AC measurements.
3. Read the AC voltage value displayed on the screen.

5.4 Resistance Measurement

1. Ensure the circuit or component to be measured is de-energized.
2. Connect the test leads across the component whose resistance you wish to measure.
3. Read the resistance value displayed on the screen in Ohms (Ω), kilo-Ohms (kΩ), or Mega-Ohms (MΩ).

5.5 Continuity Test

1. Ensure the circuit or component is de-energized.
2. Connect the test leads across the circuit or component.
3. If the resistance is below approximately 50Ω, the multimeter will emit an audible beep, indicating continuity.

5.6 Non-Contact Voltage (NCV) Detection

The NCV function allows for safe detection of AC voltage without direct contact with live wires.

1. Press and hold the "NCV" button (refer to Figure 4).
2. Move the top end of the multimeter (where the NCV sensor is located) close to the suspected AC voltage source (e.g., a wall outlet or insulated wire).
3. The multimeter will indicate the presence of AC voltage through visual (LED light) and/or audible (beeping) signals. The intensity of the signal may vary with voltage strength and proximity.

5.7 Data Hold Function

Press the "HOLD" button to freeze the current reading on the display. Press it again to release the hold and resume live measurements.

5.8 Work Light and Backlight

The multimeter includes a work light (flashlight) for illuminating the measurement area and a display backlight for improved visibility in dim conditions (refer to Figure 5). These functions are typically activated via dedicated buttons or by holding certain function keys.

6. Maintenance

6.1 Cleaning

To clean the multimeter, wipe the case with a damp cloth and a mild detergent. Do not use abrasives or solvents. Ensure the device is completely dry before use.

6.2 Battery Replacement

Replace batteries when the low battery indicator appears on the display. Refer to section 4.1 for battery installation instructions. Always use new 1.5V AAA batteries.

6.3 Storage

If the multimeter is not to be used for an extended period, remove the batteries to prevent leakage and damage to the device. Store the multimeter in a cool, dry place, away from direct sunlight and extreme temperatures.
