on-off detection, diode three file cycle switch.
3) In the frequency, duty cycle file, press the "FUNC" key, will be in the frequency,
duty cycle between the switch.
4) In the temperature range, press the "FUNC" key, will be in degrees Celsius and
Fahrenheit cycle switch.
5) In the current file, press "FUNC" key, will be in the AC current, DC current cycle
between the switch
4.3 backlight and lighting
1) During the measurement, if the ambient light is too dark, the reading is difficult,
press the " " button for more than 2 seconds, turn on the backlight and the lights,
and turn off automatically after about 15 seconds.
