This section describes how to turn on the backlight.
The backlight makes it possible to observe the display clearly in dim
locations where the LCD would otherwise be difficult to see.
Enabling the backlight function
Press and hold
Pressing and holding the HOLD key to
choose whether to enable or disable the
backlight function.
Yellow green
Ordinarily the display will be backlit in
yellow green; however, it will be backlit
in red when the instrument determines
that the circuit has negative (reverse)
phase sequence. (p. 39)
The backlight will be automatically turned
off after 30 s regardless of the hold function
setting or screen switching.
However, when the phase detection
screen shows a phase detection result, the
backlight will change in color depending of
the phase detection result after 30 s has
elapsed.
