How to use

Begin by selecting the required measurement function on the rotary switch and connect test leads or the temperature probe as appropriate. For voltage and current measurements, observe correct probe polarity and range selection; when measuring resistance or continuity, ensure the circuit power is off. For temperature readings, attach the supplied thermocouple probe securely to the measurement point and allow the reading to stabilize. Read results on the LCD and use the hold or backlight features if available to capture or view values in low-light conditions.

Usage recommendations

Use appropriate personal protective equipment and follow safety procedures when working on live circuits. Verify probe condition before use, avoid exposure of the instrument to excessive moisture or mechanical shock, and store the multimeter in a dry environment. For accurate temperature readings, ensure good thermal contact between the probe and the measured surface and allow sufficient stabilization time for high-temperature measurements.
