batteries are approaching the end of their useful life and should be
replaced. See Battery Replacement in Section 4.3 of this manual.
A low battery condition is indicated by a blinking red Low Battery
LED on the front panel. This will also cause the display to flicker along
with the blinking LED due to the power drain and low battery condition.
At this point the unit should be removed from service and the batteries
recharged.

2.2 Gas Connections
The customer must provide a means of controlling the pressure and
flowrate of the applied gas. For positive pressure applications, TAI
suggests a simple throttle valve installed in the sample line between the
sample point and the analyzer. The flowrate should be limited to
between 0.2 and 2.5 SCFH. The Sample In port is used for both sample
and calibration gas. For sampling at atmospheric pressure, connect a
pump and flow control valve
downstream
of the analyzer and draw
(rather than push) the sample through the instrument.
IMPORTANT: IF A PRESSURE REGULATOR IS USED, IT MUST
HAVE A METALLIC DIAPHRAGM. REGULATORS
WITH ORGANIC OR PLASTIC DIAPHRAGMS ARE
