MAINTENANCE
Self-Diagnostic Check
Automatic Check
The autoclave automatically performs a diagnostic self-check
on nine key components for operational continuity each time
the main power switch (toggle switch located at rear of unit) is
turned on.
An additional check may be made by the following procedure:
Operational Check
Depress "Power On"
switch and "Clear/Start"
the same time. The autoclave beeps once, signaling the
beginning of the self-diagnostic procedure.
During the first four seconds, check that all display segments
illuminate. If segments do not illuminate, call an authorized
service representative. This problem can give the operator
incorrect information if not repaired.
After self-diagnostics, the unit returns to stand-by. The lower
window displays any error found during the Operational or
Automatic self-diagnostic check procedure. See table at left
for explanation of display.
Call an authorized service representative if an unsatisfactory
check is indicated.
