How to use

Select the appropriate measurement function and range (if applicable), connect the test leads to the device and to the circuit under test, and read the value on the digital display. Observe correct polarity when measuring DC voltage and current, and switch the instrument to the continuity function to verify conductor connections. Turn the multimeter off when not in use to conserve battery life and remove the test probes from live circuits before changing measurement modes.

Usage recommendations

Use insulated test leads rated for the expected voltage and current, perform measurements within the specified ranges, and follow standard electrical safety practices. Regularly check battery condition and inspect test lead insulation for damage. For measurements beyond basic ranges or requiring advanced features, use a specialized instrument appropriate for higher accuracy or safety ratings.
