SETTING THE BACKLIGHT TIME
The backlight illuminates the display for enhanced viewing. If Button
Control is chosen the backlight button on the key pad will act as an
on/off switch and the backlight will remain on or off when the meter is
being used. When one of the other settings – 10, 20 or 30 seconds –
is chosen, the display will be illuminated for the specifi ed amount of
time after any button is pressed. As a precaution, the backlight will not
illuminate during turbidity measurements to avoid interference from stray
light.
NOTE: The backlight feature uses a signifi cant amount of power. The
longer the backlight is on, the more frequently the battery will have to be
charged if the USB/Wall Charger is not being used.
