The INHIBIT push button is used to stop the

logging is useful for monitoring recently repaired
equipment to establish trend data. It is also useful
for logging of data during full power and

PRINT INTERVAL SECTION.--The PRINT
INTERVAL section (E) contains a two-position
switch labeled 1 HOUR and 4 HOUR. This switch
sets the interval when the data logger will
automatically print a complete plant printout.
ALARM STATUS REVIEW SECTION.--
The ALARM STATUS REVIEW section (F) con-
tains a push-button switch labeled PRINT. When
depressed, the switch commands the data logger
to print out all active alarms in the ECSS. This
function is useful to the engineering officer of the
watch (EOOW) when reviewing the active alarms
and out-of-limits parameters before relieving the
watch.
