During zeroing, the ADR-1500 also performs diagnostics on the optics and
flow rates. The only allowable fault is "Background High". All other faults
will result in a failure to zero the instrument. All faults are reported with a
hex coded error flags. The faults can be determined from the following
Table
6–2, but if a fault persists, the ADR-1500 instrument requires
service.
