4. Setup

4.1 Battery Installation

The ANENG 616 Multimeter requires two 1.5V AAA batteries (not included).

1. Ensure the multimeter is turned off and disconnect all test leads from the device.
2. Locate the battery compartment on the back of the multimeter.
3. Use a screwdriver to loosen the screw securing the battery cover.
4. Remove the battery cover.
5. Insert two AAA batteries, observing the correct polarity (+ and -) as indicated inside the compartment.
6. Replace the battery cover and tighten the screw.

4.2 Connecting Test Leads

Proper connection of test leads is crucial for accurate and safe measurements.

• For most measurements (voltage, resistance, capacitance, frequency, diode, continuity, temperature):
  • Insert the black test lead into the COM (common) input jack.
  • Insert the red test lead into the INPUT jack.
• For current measurements (AC/DC Current up to 10A):
  • Insert the black test lead into the COM (common) input jack.
  • Insert the red test lead into the 10A input jack.

Warning: Always ensure test leads are securely inserted and that the correct input jacks are used for the desired measurement to prevent damage to the multimeter or personal injury.

5. Operating Instructions

The ANENG 616 Multimeter features auto-ranging for most functions, simplifying operation.

5.1 Power On/Off

Press the Power Button () to turn the multimeter on. Press and hold the Power Button to turn it off. The multimeter also features an auto-shutdown function to conserve battery life after a period of inactivity.

5.2 Measurement Functions

The multimeter automatically detects the measurement type (voltage, resistance, continuity, etc.) when in AUTO mode. Use the SELECT button to cycle through specific modes if needed.

5.2.1 AC/DC Voltage Measurement (0-600V)

• Connect the black lead to COM and the red lead to INPUT.
• The multimeter will automatically detect AC or DC voltage. If necessary, press SELECT to manually switch between ACV and DCV.
• Connect the test leads in parallel to the circuit or component to be measured.

5.2.2 AC/DC Current Measurement (0-10A)

• Connect the black lead to COM and the red lead to 10A.
• The multimeter will automatically detect AC or DC current. If necessary, press SELECT to manually switch between ACA and DCA.
• Connect the multimeter in series with the circuit to measure current.
• Caution: Do not measure current on circuits exceeding 10A.

5.2.3 Resistance Measurement (0-60MΩ)

• Connect the black lead to COM and the red lead to INPUT.
• Ensure the circuit is de-energized before measuring resistance.
• Connect the test leads across the component to measure its resistance.

5.2.4 Capacitance Measurement (6nF-60mF)

• Connect the black lead to COM and the red lead to INPUT.
• Discharge capacitors before testing to prevent damage to the multimeter.
• Connect the test leads across the capacitor.

5.2.5 Frequency Measurement (0-10MHz)

• Connect the black lead to COM and the red lead to INPUT.
• Connect the test leads to the signal source.

5.2.6 NCV (Non-Contact Voltage) Detection

• No test leads are required for this function.
• Bring the top part of the multimeter (where the NCV sensor is located) close to the AC voltage source.
• The analog bar index on the display will rise, "EF" may be displayed, and an alarm beep will sound, indicating the presence of AC voltage.

5.2.7 Diode Test and Continuity Test

• Connect the black lead to COM and the red lead to INPUT.
• Press SELECT to cycle between Diode Test and Continuity Test modes.
• For Diode Test: Connect the red lead to the anode and the black lead to the cathode of the diode. The display will show the forward voltage drop. Reverse the leads to check for open circuit.
• For Continuity Test: Connect the test leads across the circuit or component. A continuous beep indicates low resistance (continuity).

5.2.8 Firewire Detection (Live Wire)

• Connect the black lead to COM and the red lead to INPUT.
• Insert the red test lead into the socket hole.
• The display will show "EF" without a beep for a neutral line, or "---" with an alarm beep for a live wire.

5.2.9 Temperature Measurement (0-1000℃ / 0-1832℉)

• Connect the thermocouple to the COM and INPUT jacks, observing polarity.
• Place the thermocouple tip on or near the object whose temperature is to be measured.
• Press SELECT to switch between Celsius (℃) and Fahrenheit (℉).

5.3 Additional Functions

• Data Hold: Press the H/⚡ button briefly to hold the current reading on the display. Press again to release.
• Flashlight: Press and hold the H/⚡ button to turn the built-in LED flashlight on or off. This is useful for illuminating dark work areas.
