Automatic Backlight Off
Press T to select the backlight level (low, high, or off.) In
low or high, the backlight turns off automatically after a
given period. This period is also preset to 15 minutes and
can be set to a maximum of 99 minutes from the setup
menu. If the period is set to 0, the backlight is on
indefinitely and can only be turned off by pressing T or
turning the meter off.
Note
See Chapter 5 for power off and backlight off
setup information.
Low Battery Indication
A constant battery icon ( B) in the upper left corner of
the display notifies you that the batteries are low and
should be replaced.
WWarning
To avoid false readings, which could lead to
possible electric shock or personal injury,
replace the batteries as soon as the battery
icon ( B) appears.
A flashing battery icon means that battery failure is
imminent. The backlight cannot be used in this condition.
MIN MAX and FAST MN MX features turn off. For Model
189, logging and communications also cease.
