Check Memory The instrument only has enough space to store < 50 readings
before the memory will be full. The exact number remaining can
be checked using the View Readings option.
Memory Full There is no space left in the memory to store new readings. Both
the Store and the Logging options will be disabled until the
memory has been cleared. The stored readings should be
downloaded to your PC using the optional Analyzer Data
Manager before you clear the memory.
Battery Low The instrument does not have enough battery power to operate
for a full day. Recharge the instrument or connect it to an external
power supply.
Service Due It has been 12 months or more since your instrument was
returned for service. Its performance and accuracy may be
impaired: service it now.
Flow Fail The instrument’s gas inlet or outlet may be blocked. This warning
is most often caused by a dirty or water-logged sample filter.
Replace the sample filter and check for blockage(s) in the sample
tubes. Alternatively, a small adjustment may be made to the low
flow detection point to compensate for minor changes in the
performance of the instrument’s pump; consult your New
Brunswick service technician.
