Diagnostic Command Code Listing
When DIGI-POT is not moving, this command clears
the DIGI-POT counter. Once the DIGI-POT is
moving, this command reads the DIGI-POT counter.
The counter will contain the number of interrupts
generated since counter was last cleared.
DIGI-POT has 32 interrupts per rotation.
To check the lamps,
enter ‘+’ in Char 7 with
settings in Char 6 - 0.
To return to Normal
Operation, enter ‘-’ in
Char 7 or turn off
power.
