Flir Extech EX320 Multimeter F.A.Q.

How do I measure AC voltage with the Flir Extech EX320 Multimeter?

To measure AC voltage, set the rotary switch to the 'V~' position. Connect the test leads to the multimeter and the circuit, ensuring the red lead is connected to the 'VΩ' jack and the black lead to the 'COM' jack. Place the probes across the component or circuit you wish to measure. The reading will display on the screen.

What should I do if the multimeter does not power on?

First, check the battery compartment to ensure the batteries are properly installed and have sufficient charge. Replace the batteries if necessary. If the issue persists, inspect the battery contacts for corrosion and clean them if needed.

How can I test a diode using the EX320 Multimeter?

Turn the rotary switch to the diode test position, indicated by a diode symbol. Connect the red test lead to the anode and the black test lead to the cathode of the diode. A typical forward-biased diode will show a voltage drop between 0.5V to 0.8V. If the reading is different, check the diode for faults.

What is the proper way to measure resistance with this multimeter?

Set the rotary switch to the 'Ω' position. Insert the red lead into the 'VΩ' jack and the black lead into the 'COM' jack. Connect the probes across the resistor or circuit. Ensure the circuit power is off to avoid damage. The resistance value will appear on the display.

How do I calibrate the Flir Extech EX320 Multimeter?

The EX320 is factory calibrated. If calibration is needed, it should be performed by a qualified technician. Regular calibration intervals should be maintained as per the usage and environmental conditions.

What precautions should I take when using the EX320 Multimeter?

Always ensure the multimeter is set to the correct measurement type and range. Do not exceed the maximum input values specified for each measurement type. Use proper personal protective equipment when working with high voltages.

How can I measure current with the EX320?

To measure current, switch to the 'A~' or 'A=' position depending on AC or DC current. Connect the red lead to the 'A' jack and the black lead to the 'COM' jack. Break the circuit and insert the multimeter in series. Ensure the current does not exceed the multimeter’s rated capacity.

What should I do if the readings are unstable or inaccurate?

Check the test leads and connections for any damage or poor contact. Replace damaged leads. Ensure the multimeter is properly calibrated and the batteries are charged. Avoid measuring in environments with high electromagnetic interference.

How do I maintain the multimeter in good working condition?

Keep the multimeter clean and dry. Store it in a protective case when not in use. Regularly inspect the test leads for wear and replace them as needed. Follow the manufacturer’s guidelines for battery replacement and calibration.

Can the EX320 measure temperature, and if so, how?

The EX320 model does not support temperature measurement. Consider using a compatible temperature probe with a multimeter that has this feature for accurate temperature readings.
