Target Sensor Calibration
The calibration pots and indicators for the sensors are on the Dolly Board. The
Dolly Board is mounted on the West side of the pedestal and is visible through
the removable window in the North cover. Each sensor assembly contains three
individual sensors, each with its own calibration pot on the Dolly Board.
The window allows you to monitor the sensor status during targeting and cali-
brate the sensors without removing the covers. Errors during targeting are an
indication that sensor calibration and/or cleaning may be necessary. If the red
ERR LED flashes after targeting, this indicates that one or more sensors are
incorrectly set. In normal operating mode, the "light meter" LEDs are used as
individual sensor indicators as marked on the board. Therefore, one or more of
these LEDs will be on to indicate which sensor(s) need calibration.
