The D902/3 will not allow decimal values to be entered as
a CAL constant, so round to the nearest whole number. In
this case 91%.
Acceptable input ranges for the CAL constant are shown in
Table 8. Values outside of this range will result in an
OVER! or UNDER! display. Non-whole number entries will
result in a RANGE! display. Enter an appropriate value.
The DAMP key allows the selection of time duration
between display updates. The value selected and entered
will result in display updates of
n × 2 = seconds between updates
Acceptable input ranges for the DAMP constant are shown
in Table 9. Values outside of this range will result in an
OVER! or UNDER! display. Entry of an appropriate value
is required.
The TEST key is used for diagnostic purposes. It displays
the operand presently available at the analog to digital
converter. This value will always be in the range of 0 to
255.
