Flir Extech EX505 Multimeter F.A.Q.

How do I measure AC voltage using the Flir Extech EX505 Multimeter?

To measure AC voltage, turn the rotary switch to the V~ position. Connect the test leads to the COM and V terminals, then place the probes across the circuit. Ensure you read the voltage within the display range.

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

Check if the battery is correctly installed and has enough charge. Replace the battery if necessary and ensure the battery compartment is clean and the contacts are free of corrosion.

How can I test a diode using the EX505?

Set the rotary switch to the diode test position, indicated by a diode symbol. Connect the red lead to the anode and the black lead to the cathode. A typical forward voltage drop reading should be between 0.5 to 0.8 volts.

What is the procedure for measuring resistance?

Turn the rotary switch to the Ω position. Insert the test leads into the COM and Ω terminals. Place the probes across the component to measure its resistance, making sure the circuit is de-energized.

How do I perform a continuity test with the EX505?

Switch to the continuity test mode by selecting the continuity symbol. Connect the test leads across the component or circuit. A continuous beep indicates continuity.

Why is the display showing an 'OL' reading?

'OL' indicates an overload condition, meaning the measurement exceeds the range. Adjust to a higher range setting for the parameter being measured.

How to replace the fuse in the Flir Extech EX505?

To replace the fuse, turn off and disconnect the multimeter. Open the back cover by removing the screws. Identify and replace the blown fuse with a fuse of the same rating, then reassemble the multimeter.

Can I measure temperature with the EX505?

Yes, the EX505 can measure temperature using the included Type K thermocouple. Connect the thermocouple to the multimeter and set the rotary switch to the temperature measurement setting.

What maintenance steps should be regularly performed on the EX505?

Regularly check the condition of the test leads, ensure the battery is charged, and keep the multimeter clean by wiping with a dry cloth. Avoid using solvents or abrasive materials.

How do I calibrate the Flir Extech EX505 Multimeter?

Calibration should be performed by a qualified technician. If calibration is needed, refer to the service manual or contact Flir customer support for detailed instructions.
