In practice, some empirical modication is required; this helps to compensate
for the non-ideal performance of the meter. For example, the actual factor for
argon is 1.395, rather than the 1.401 estimated in the example. Please consult
AMETEK Process Instruments for assistance, before running gases that are not
listed in the menu on the 3050-RM Analyzer.
If a custom gas is entered, the conversion to units of dew point will be
based on an ideal gas model, without any enhancement factor.
Gas Saver
In the default conguration the 3050-RM Analyzer runs with the internal
bypass valve open, so that the total ow through the analyzer is greater
than 1 SLPM. This high sample ow rate helps to improve the response
speed of the system. The gas-saver feature allows the user to control the
state of the bypass valve so that the analyzer runs on a sample ow rate
of 150 SCCM. The operation of the valve can be controlled by checking
the Gas Saver box (to close the bypass valve) or leaving it unchecked(to
leave the bypass valve open).
Sensor Saver
In the default conguration the 3050-RM Analyzer operates with a rapid
cycle time to minimize system response time. The sensor-saver feature al-
lows the analyzer to operate with a slow cycle time, maximizing the cell life
but minimizing system response time. The operation of the valve can be
controlled by checking the Sensor Saver box (to operate with a slow cycle
time) or leaving it unchecked (to operate with a rapid cycle time).
