The Streams Tab (Section 5.10) has a Gain Calculator where the user can
enter the Calibration Gas Value, the Analyzer Reading and the Current Gain
Factor. The calculator will calculate the value for the new gain, however,
the user will still have to enter it in the GUI or through the keypad.
g) Once the new gain is entered, the analyzer is calibrated. Allow the analyzer to run one or
two more cycles to verify that the analyzer is reading correctly.
h) Turn the 3 way valve back to process gas. Allow the analyzer reading to stabilize on the
process gas.
i) If the analyzer was placed in Reference mode then disable the Manual Sequencer so that
the analyzer will return to its normal auto sequence.
j) Press the Bypass button on the keypad to take the analyzer out of Bypass mode so that
any alarm outputs will be re-activated.
6.6.2 Manually Initiated Auto Calibration
If this option is employed, the analyzer is equipped with a manually operated 3-way valve that
can be used to introduce calibration gas to the analyzer.
To perform a manually initiated auto calibration:
a) Place the analyzer in Bypass mode by pressing the Bypass button on the handheld
keypad. This will disable any alarm outputs.
b) Connect calibration gas to the Calibration port of the analyzer. Set the output pressure of
the calibration standard to the same pressure that the sample gas is normally provided at
(this is typically 15 psig).
c) Turn the 3-way valve to introduce calibration gas to the analyzer.
d) Enter the value of the calibration standard in the Calibration tab of the Streams tab
(Section 5.10)
e) Initiate an Auto Calibration run, either from the GUI or from the keypad.
f) The analyzer will run the Auto Calibration a protocol according to the setup of the
Calibration tab f the Streams. The analyzer will run the total number of runs defined by
“Consecutive Runs”. It will then average the number of results together as defined by
Runs to Average. A new Gain Factor will be automatically calculated using the
calibration gas value defined in Cal.Gas Concentration.
g) When the Auto Calibration is complete the analyzer will automatically return to the
previously defined automatic sequence.
