5.3 Digital-to-analog converter
Fig. 96
The printer uses a Digital to Analog Converter (DAC) to control the operation
of the mirror galvanometer. This dialog allows you to manually manipulate
the DAC and thus the position of the mirror.
Enter the Desired Voltage - There are two ways to enter an output voltage
and thus move the mirror. You may type the voltage setting into the edit field
and then press the Output button, or you may move the slider control. The
valid voltage range is -10.0 volts to +10.0 volts. When the slider is at the
middle of its range, the output is zero volts.
Output Button - When pressed, this button will cause the voltage setting in
the edit field to be set at the DAC output.
Oscillate Button - When pressed, this button will begin oscillating the mirror
at a frequency of 20 hertz. The amplitude of the oscillation will be deter-
mined by the setting of the voltage entry field at the time the oscillate button
was pressed. This is very useful when trying to calibrate the galvanometer.
Calibration of the galvanometer should only be performed by qualified fac-
tory personnel.
