8. Backlight, LED light, and Buzzer
Backlight
This instrument automatically turns the backlight and LED
light on and off depending on the ambient brightness.
Once these lights turn on, they stay on for about 15 s. The
ambient brightness is detected by the illuminance sensor.
These lights can also be turned off permanently.
• If the surface of the illuminance sensor is dirty, the
instrument may not be able to turn the backlight and
LED light on and off normally. Keep the surface of the
illuminance sensor clean.
• You cannot adjust the sensitivity of the illuminance
sensor. If you want to force the lights to turn on, cover
the sensor so that it is dark.
• Even when the environment is not dark, these lights
turn off automatically if the instrument is not operated
for about 2 minutes (except when a measurement is in
progress or the live circuit warning is activated).
