How to use

Select the required measurement function with the rotary selector and connect the test leads to the appropriate input terminals. For voltage measurements, place the test probes across the circuit or component while observing polarity for DC readings. For current measurements, place the meter in series with the circuit following the meter’s rated input limits. Use the continuity mode to detect short circuits or check connections; the meter indicates continuity when resistance falls below the internal threshold. Always power down and discharge capacitive elements in a circuit where possible before performing resistance or continuity checks.

Usage recommendations

Before each use, inspect test leads and probe tips for damage and replace them if worn. Observe correct function selection and input ranges to avoid overloading the instrument. For higher-voltage or specialized measurements, use a meter with appropriate ratings. Store the multimeter in a dry, dust-free place and replace batteries promptly to maintain reliable readings.
