Flir Extech EX613 User's Guide

To measure AC current, set the rotary switch to the AC current position. Open the clamp jaws and close them around the conductor. Ensure the conductor is centered for accurate readings. The current value will display on the screen.
"OL" indicates an overload condition. Ensure that the measurement range is set correctly for the expected current or voltage. If necessary, switch to a higher range.
Turn the rotary switch to the resistance (Ω) position. Connect the test leads to the circuit and ensure the circuit is de-energized. The resistance value will appear on the display.
Check the battery compartment to ensure the batteries are installed correctly and have sufficient charge. Replace the batteries if needed. Also, check the power button functionality.
Press the "HOLD" button during a measurement to freeze the displayed value. Press it again to release the hold and return to normal mode.
Yes, the EX613 can measure DC current. Set the rotary switch to the DC current position and follow the same procedure as for AC current measurement.
Keep the meter clean and dry. Store it in a protective case when not in use. Periodically check and replace batteries. Avoid exposure to extreme temperatures and humidity.
Calibration should be performed by a qualified technician. Contact the manufacturer or a certified service center for calibration services.
Ensure that the test leads are properly connected and that the circuit is stable. Fluctuations could also be due to interference or a loose connection.
Set the rotary switch to the continuity test position. Connect the test leads to the circuit. A continuous tone indicates continuity.
