DESCRIPTION
Records total hours of air compressor run time. Hold the
ENTER key for five seconds to reset to "0".
Displays the number of hours that have elapsed since the
membrane air filters were changed. Records actual hours
(ie. 100 hours is displayed as 100). Hold ENTER key for
five seconds to reset to "0".
Records the total number of operational hours for the CA
system air compressor. Records total hours in increments
of 10 hours. (i.e. 3000 hours displayed as 300)
Displays the current operating status of the air
compressor (ON or OFF).
