Error Messages
The StarBright displays various error messages when operated outside its normal range.
Over range:
When the power or energy being measured exceeds the range of the
measurement scale being used, the “over” message is displayed, but the reading still appears
on the display. If the power or energy exceeds the maximum by more than 10%, the reading
on the display is blanked.
Low Battery:
When the battery is almost discharged, the Battery icon will have only 1 segment
left. This means the battery is ¾ empty. At this stage, the StarBright should be connected to
the charger. It will operate normally and charge while connected to the charger.
Sat:
When the Photodiode current exceeds 1mA, and the detector starts to saturate, or the
Pyroelectric voltage exceeds the maximum, the message "sat” (=saturated) is displayed.
