LED STATUS INDICATORS
a. Diagnostic/Unit Alarms
Table 4-1 lists the types and status of
alarms that will be encountered. (See
Section 5, TROUBLESHOOTING, for a de-
tailed description of each fault).
b. When the electronics determines a calibra-
tion is recommended, the CALIBRATION
RECOMMENDED LED is on solid.
c. The CAL LED turns on when a calibration is
recommended and is on during the calibra-
tion process. During calibration, the CAL
LED can be flashing, which would indicate
operator action is requested, or on solid,
which indicates calculations and measure-
ments are in progress.
