Flir DM220 User's Guide

To change the battery, first ensure the multimeter is powered off. Remove the protective holster, then unscrew the battery compartment at the back. Replace the old batteries with new AA batteries, ensuring correct polarity, and reassemble the device.
If the display is not turning on, check the battery to ensure it’s not depleted. Replace the battery if necessary. Inspect the battery contacts for corrosion and clean them if needed. If the issue persists, consult the user manual or contact support.
To measure AC voltage, set the dial to the AC voltage position. Connect the test leads to the multimeter: the black lead to the COM terminal and the red lead to the VΩ terminal. Place the probes across the circuit or component to be measured, and read the displayed voltage.
Calibration of the Flir DM220 should be performed by a professional calibration service. Regular calibration ensures measurement accuracy. Contact Flir support for recommended calibration services.
Turn the dial to the continuity test position. Connect the test leads: black to COM and red to VΩ. Test the circuit by placing the probes on the points to be checked. A continuous circuit will emit a beep.
Inaccurate readings can result from several factors: low battery power, incorrect range setting, or faulty test leads. Ensure the battery is fresh, the range is correctly set, and the leads are undamaged. Recalibration might be necessary.
Yes, to measure DC current, set the dial to the appropriate DC current range. Insert the black lead into the COM jack and the red lead into the mA or A jack, depending on the expected current. Connect the meter in series with the circuit.
Regularly inspect the probes for damage or wear. Clean the metal tips with a dry cloth and ensure the insulation is intact. Store the probes with the multimeter in a protective case to avoid damage.
Ensure proper connection of test leads and set the dial to the correct measurement type and range. Do not exceed the maximum input limits specified. Use the multimeter in dry environments and avoid handling with wet hands.
To test resistance, set the dial to the resistance (Ω) setting. Attach the black lead to COM and the red lead to the VΩ jack. Place the probes across the component to be measured, ensuring circuit power is off. Read the resistance value on the display.
