‘Smart Measurement Mode
Tris measirement modis enabled by default when turning on the nstrument. In this mode, DG voltage, resistance, and on-off can
e measured, and the measuring signal can be recognized automatlcaly.
1) Prass the power button to tum on the instrumen, the display will show" ", and enfer into the smart measurement mode.
2) The meter will automaticaly recognize the measured signal by toushing the probe to the power supply or the resistance.
) When th resistanco is measurod, resistance 500, the buzzer sounds.
) Read the measurement results from the display screen.
Note: miimu discemible voltage in this mode is 0.8V

/A\Weming
@ Do not measure voltage above 110V, or the Instrument will be damaged.
@ Pay special attention to safety when measuring high voltage to avoid electric shock or personal injury.
@ Before use, test the known voltage with the instrument and confirm that the instrument functions properly.
Note: when the messuring circut Is on o off, the reading may be affected by other cirouits between the meter and pen.
