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
The analyzer must be equipped with a manually operated 3-way valve that can be used to
introduce calibration gas to the analyzer.
a) Place the analyzer in Bypass 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 normally runs 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 of the
GUI.
e) Initiate an
Auto
calibration run, either from the GUI or from the keypad.
f) The analyzer will run the Auto Calibration according to the setup of the
Stream/Calibration run. 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.
h) When the calibration is complete, turn the 3 way valve back to process gas.
i) Press the
Bypass
button on the keypad to take the analyzer out of Bypass mode so that
any alarm outputs will be re-activated.
