Flir CM85 Clamp Meter F.A.Q.

How do I measure AC/DC current using the Flir CM85 Clamp Meter?

To measure AC/DC current, switch the meter to the current measurement mode, open the clamp jaws by pressing the trigger, and place them around the conductor. Ensure the conductor is centered in the jaws for accurate measurements.

What should I do if the display shows 'OL' while measuring voltage?

'OL' indicates an overload condition. Select a higher voltage range on the meter to obtain a reading within the measurable range.

How can I measure resistance with the Flir CM85?

Turn the rotary switch to the resistance measurement position, connect the test leads to the circuit, and ensure the power is off. The meter will display the resistance value.

What is the correct way to calibrate the Flir CM85 Clamp Meter?

Calibration should be performed by a qualified professional. It's recommended to follow the manufacturer's guidelines and use a proper calibration source to ensure accuracy.

How do I replace the batteries in the Flir CM85?

Turn off the meter and remove the test leads. Unscrew the battery compartment cover on the back of the device, replace the old batteries with new ones, ensuring correct polarity, and reattach the cover.

What is the procedure to test continuity with the Flir CM85?

Switch to continuity mode, connect the test leads across the component or circuit being tested. A continuous circuit will generate an audible beep and the display will show a low resistance value.

How can I ensure accurate measurements with the Flir CM85?

Ensure the meter is properly zeroed, use correct measurement mode, position the conductor at the center of the clamp, and avoid external electromagnetic interference during measurements.

What should I do if the Flir CM85 is not turning on?

Check the battery installation for proper orientation and replace them if necessary. If the problem persists, inspect the fuse and internal connections.

How do I perform a diode test with the Flir CM85?

Select the diode test function, connect the red lead to the anode and the black lead to the cathode of the diode. The meter will display the forward voltage drop.

What maintenance practices should I follow for the Flir CM85?

Regularly check for physical damage, clean the meter with a soft, damp cloth, store it in a dry place, and periodically check calibration to maintain accuracy.
