11.6.6 Service Expired
During the warm up of the instrument, a check is done to
verify if the service date has expired. If the instrument is
configured to pause if service is due, the user is asked to
continue or not. If yes is selected, the user can continue
using the instrument as normal. If no is selected, the user
is forced to switch the instrument off and return the
instrument for service.
The service due date is only displayed during the warm
up of the instrument and there will be no indication during
normal operation.
11.6.7 Service Required
During warm-up, if the ‘SERVICE REQUIRED’ flag is
displayed and an audible alarm and Red LED’s are
activated, the instrument has detected a fault in the service
memory during start-up and is unable to continue without
re-servicing.
Fig. 11.13 Service Required
The instrument must be switched off immediately. Follow
appropriate action required by your company for servicing.
An extended period is possible allowing the user to
continue to use the instrument for a set amount of time
after the service due has expired. When this extended
period is over, the user will be forced to switch off the
instrument and return the instrument for service.
