Basic Usage and Operation Tips
Before using the Kenwood-dm-81, ensure the device is powered on and the correct measurement mode is selected. Always start with the highest range to prevent damage when measuring unknown voltages or currents. Use the test leads properly by connecting the black lead to the COM terminal and the red lead to the appropriate input terminal based on the measurement type. For resistance and continuity tests, ensure the circuit power is off before measuring. Utilize the data hold feature to freeze readings when working in hard-to-see locations.
Troubleshooting and Maintenance
If the multimeter displays erratic readings or fails to power on, check the battery and replace it if necessary. Inspect test leads for any visible damage or wear, as faulty leads can cause inaccurate measurements. Clean the device regularly with a soft, dry cloth and avoid exposure to moisture or extreme temperatures. If the device is not functioning correctly after basic troubleshooting, consult the schematic diagrams in the manual for detailed repair guidance.
Safety Reminder
Always observe safety precautions when using the Kenwood-dm-81. Avoid measuring voltages or currents exceeding the specified limits to prevent electric shock or equipment damage. Disconnect power from circuits before testing resistance or continuity. Use insulated test leads and wear appropriate personal protective equipment when working with high voltages. Follow all local electrical safety regulations to ensure safe operation.
