Flir Extech 380940 Clamp Meter F.A.Q.

How do I measure AC current with the Flir Extech 380940 Clamp Meter?

To measure AC current, set the rotary switch to the AC current (A~) position. Open the clamp jaws and place them around the conductor to be measured. Ensure the conductor is centered within the clamp for accurate readings. The current value will be displayed on the screen.

What should I do if the clamp meter does not power on?

If the clamp meter does not power on, check the battery compartment to ensure the batteries are installed correctly and have sufficient charge. Replace the batteries if necessary. Also, inspect the battery contacts for corrosion and clean them if needed.

How can I use the data hold function on the Extech 380940?

To use the data hold function, press the 'HOLD' button while the desired measurement is displayed. The reading will be frozen on the screen, allowing you to record or examine it later. Press 'HOLD' again to release the hold function and return to normal operation.

What is the procedure to measure DC voltage with this clamp meter?

Set the rotary switch to the DC voltage (V-) position. Connect the red test lead to the VΩ jack and the black test lead to the COM jack. Touch the test probes to the circuit under test and read the voltage on the display.

How do I calibrate the Extech 380940 Clamp Meter?

Calibration of the Extech 380940 should be performed by a qualified technician. If you suspect calibration is needed, contact Flir Extech customer support or an authorized service center for assistance.

What are the maintenance tips for the Extech 380940 Clamp Meter?

Regularly inspect the clamp meter for any physical damage. Keep the device clean and dry. Avoid exposing it to extreme temperatures or humidity. Replace batteries when the low battery indicator appears. Store the meter in a protective case when not in use.

How do I measure resistance with the Flir Extech 380940?

To measure resistance, turn the rotary switch to the resistance (Ω) position. Insert the red test lead into the VΩ jack and the black lead into the COM jack. Connect the test probes across the component to be measured and read the resistance value on the display.

What should I do if the readings on my clamp meter are erratic?

Ensure that the test leads and clamps are properly connected and not damaged. Check that the batteries are in good condition. If problems persist, reset the device by turning it off and on again. If erratic readings continue, consult the user manual or contact technical support.

Can I measure frequency with the Extech 380940, and if so, how?

Yes, you can measure frequency with the Extech 380940. Set the rotary switch to the Hz position. Use the appropriate test leads to connect to the circuit, and the frequency will be displayed on the screen. Ensure the circuit is live for accurate frequency measurement.

How should I store the clamp meter to ensure its longevity?

Store the clamp meter in a dry, cool place away from direct sunlight. Use a protective case to prevent physical damage. Remove the batteries if the device will not be used for an extended period to prevent battery leakage.
