2. Safety Information

To ensure safe operation and avoid damage to the meter, please read and follow all safety instructions carefully. Improper use can result in electric shock or damage to the instrument.

• Always adhere to local and national safety codes.
• Do not apply voltage or current that exceeds the maximum specified limits for the meter.
• Exercise extreme caution when working with live circuits. Voltages above 30V AC RMS, 42V peak, or 60V DC pose a shock hazard.
• Before measuring current, ensure the circuit is de-energized and the test leads are properly connected.
• Never use the meter if it appears damaged or if the insulation on the test leads is compromised.
• Ensure the battery cover is securely closed before operation.
• Do not operate the meter in explosive gas, vapor, or dusty environments.
• Remove test leads from the circuit before changing functions.
• Replace batteries immediately when the low battery indicator appears to ensure accurate readings.

4. Setup

4.1 Battery Installation

The ANENG PN108 requires two AAA batteries (not included) for operation.

1. Ensure the meter is turned off.
2. Locate the battery compartment on the back of the meter.
3. Use a screwdriver to open the battery compartment cover.
4. Insert two AAA batteries, observing the correct polarity (+ and -).
5. Replace the battery compartment cover and secure it with the screw.

4.2 Connecting Test Leads

For voltage, resistance, capacitance, frequency, diode, continuity, and temperature measurements, connect the test leads as follows:

• Insert the red test lead into the 'VΩHz' input jack.
• Insert the black test lead into the 'COM' (common) input jack.
• For temperature measurements, connect the temperature probe to the 'VΩHz' and 'COM' jacks, ensuring correct polarity if applicable.

5. Operating Instructions

Turn the rotary dial to select the desired measurement function. Press the 'SEL' button to cycle through sub-functions if available within a dial position.

5.1 AC/DC Voltage Measurement

1. Turn the rotary dial to the 'V' position. The meter will default to AC voltage. Press 'SEL' to switch to DC voltage if needed.
2. Connect the red test lead to the positive side of the circuit and the black test lead to the negative side (or neutral/ground for AC).
3. Read the voltage value on the LCD display.

5.2 AC/DC Current Measurement (Clamp)

The clamp jaw allows for non-contact current measurement.

1. Turn the rotary dial to the 'A' position. The meter will default to AC current. Press 'SEL' to switch to DC current if needed.
2. Open the clamp jaw and enclose only one conductor of the circuit. Ensure the conductor is centered within the jaw for accuracy.
3. Read the current value on the LCD display.

5.3 Resistance Measurement

1. Turn the rotary dial to the 'Ω' position.
2. Ensure the circuit is de-energized before measuring resistance.
3. Connect the test leads across the component to be measured.
4. Read the resistance value on the LCD display.

5.4 Capacitance Measurement

1. Turn the rotary dial to the 'Capacitance' position (often shared with Hz or Diode). Press 'SEL' if necessary.
2. Ensure the capacitor is fully discharged before measurement.
3. Connect the test leads across the capacitor terminals.
4. Read the capacitance value on the LCD display.

5.5 Frequency (Hz) Measurement

1. Turn the rotary dial to the 'Hz' position.
2. Connect the test leads across the circuit or signal source.
3. Read the frequency value on the LCD display.

5.6 Temperature Measurement

1. Turn the rotary dial to the 'Temp' position (often indicated by a thermometer symbol).
2. Connect the temperature probe to the meter's input jacks.
3. Place the tip of the temperature probe on or in the object whose temperature is to be measured.
4. Read the temperature value on the LCD display. Press 'SEL' to switch between Celsius and Fahrenheit.

5.7 Diode Test and Continuity Test

1. Turn the rotary dial to the 'Diode/Continuity' position (often indicated by diode and buzzer symbols). Press 'SEL' to switch between functions.
2. Diode Test: Connect the red test lead to the anode and the black test lead to the cathode of the diode. The display will show the forward voltage drop. Reverse the leads to check for open circuit.
3. Continuity Test: Connect the test leads across the circuit or component. If resistance is below approximately 50Ω, the buzzer will sound, indicating continuity.

5.8 NCV (Non-Contact Voltage) Detection

1. Turn the rotary dial to the 'NCV' position.
2. Move the top part of the meter (NCV sensor) close to the conductor or outlet.
3. If AC voltage is detected, the indicator light will flash red, and an audible beep will sound, with the frequency of beeps increasing as the voltage strength increases.

Figure 5.4: NCV detection in progress. When AC voltage is detected, the meter flashes red and emits an alarm sound.

5.9 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 readings.

5.10 Backlight and Flashlight

• Backlight: Long press the 'BL' button to turn the LCD backlight on or off.
• Flashlight: Long press the flashlight button (often integrated with 'BL' or a separate button) to turn the flashlight on or off.

6. Maintenance

6.1 Cleaning

Wipe the meter with a damp cloth and mild detergent. Do not use abrasives or solvents. Keep the input terminals free of dirt and moisture.

6.2 Battery Replacement
