To measure AC voltage, turn the rotary switch to the AC voltage position (V~). Connect the test leads to the COM and V terminals, then place the probes across the component or circuit under test. Read the measurement on the display.
First, check the battery compartment to ensure the batteries are correctly installed and have sufficient charge. If the issue persists, inspect the fuse and replace it if necessary. Ensure the rotary switch is set correctly.
To measure resistance, turn the rotary switch to the resistance position (Ω). Connect the test leads to the COM and Ω terminals, then place the probes across the resistor. Ensure the component is not powered. The resistance value will display on the screen.
Calibration should be performed by a qualified technician. Refer to the service manual for calibration instructions or send the device to an authorized service center to ensure accurate measurements.
Press the 'LOG' button to enter data logging mode. Use the navigation buttons to select the desired logging interval. Press 'LOG' again to start logging. To stop, press 'LOG' once more. Retrieve data via USB connection to a computer.
Yes, connect a thermocouple to the K-type thermocouple input. Set the rotary switch to the temperature position (°C/°F) and read the temperature from the display. Ensure the thermocouple is calibrated for accurate readings.
Refer to the user manual for a list of error codes and their meanings. Common solutions include checking connections, ensuring the correct measurement mode is selected, and resetting the device by turning it off and on.
Set the rotary switch to the continuity test position. Connect the test leads to the COM and Ω terminals. Place the probes on either side of the component. A continuous circuit will trigger an audible beep.
Regularly calibrate the multimeter, replace old batteries, use the correct measurement range, and ensure the test leads are in good condition. Avoid measuring in environments with high electromagnetic interference.
Keep the device clean and dry, regularly inspect and replace test leads if damaged, and store in a protective case when not in use. Replace batteries as needed and periodically check calibration.
