Backlight
When the instrument is operating in low-light conditions a photocell will detect this situation and permit the backlight to function.
Battery Check
When the voltage of the batteries is low, the device will indicate “Lo bAtt” on the display before resuming normal display functions.
When the batteries are low the backlight will not operate in order to conserve power while the user completes his operations. Replace
batteries as soon as possible in a safe location after “Lo bAtt” is noticed, this will ensure backlight operation, and avoid possible
malfunctioning. Do not attempt to calibrate the instrument if the “Lo bAtt” has been displayed since the new calibration values may
not be properly stored to memory.
