Sealey Professional Digital Multimeter - 6 Function - TM100

Connect the black lead to the COM port and the red lead to the VΩ port. Select the DCV or ACV setting, depending on the type of voltage you are measuring.

Connect the black lead to the COM port and the red lead to the mA or A port, depending on the current range. The multimeter must be connected in series with the circuit.

Select the continuity setting (often marked with a diode symbol). Touch the probes to the two points in the circuit. If there is continuity, the multimeter will beep.

This safety rating indicates the multimeter is designed to withstand transient overvoltages in Category III environments, such as distribution panels and busbar, up to 600 volts.

It is recommended to calibrate your multimeter annually or as needed to maintain accuracy.

Disconnect the leads from the circuit immediately and check the function and range settings. You may have exceeded the multimeter's measurement capacity.

The TM100 is rated for CATIII 600V, which allows use on circuits up to 600V in appropriate environments. Always follow safety precautions and ensure the meter is suitable for the specific application.

Check the battery and replace if necessary. Ensure the battery is correctly installed.

Check the test leads for damage. Ensure the function and range settings are correct for the measurement.

Replace the batteries with new ones.

Make sure the function is set to continuity (often indicated by a diode symbol) and the circuit is complete.
