How to use

Set the rotary selector to the desired measurement function and range, connect the test leads to the appropriate input terminals, and apply the probes to the measurement points. For voltage measurements, place the probes across the circuit or component; for current measurements, use the correct input and route the current through the meter as directed by the manufacturer's instructions. Observe the display for readings and any warning indicators; switch off the meter and remove probes when finished. Follow standard electrical safety practices while operating the multimeter.

Usage recommendations

Verify the correct function and range before measuring, especially when switching between high-voltage and high-current modes. Use appropriate personal protective equipment and ensure the test leads and meter are rated for the measured values. Store the multimeter in a dry, dust-free environment and perform periodic checks of insulation and lead condition to maintain measurement accuracy and safety.
