Calibration Setup Checks

Calibration Setup Checks
Check that the correct calibration
gas values have been entered into
the control unit.
- Select the Setup tab from the
configurator software and check that
the calibration gas values entered
match the analyzed concentration of
the cylinders.
Ensure that your calibration line is
not contaminated with such things
as pipe dope, cutting fluid, oil or
solvents. All these contaminants
produce hydrocarbon vapors that
interfere with the proper calibration
of your analyzer leading to lower-
than-expected oxygen readings.

Calibration Gas Check
Are the calibration gas cylinders turned on? Are they empty?
Does the calibration gas bottle pressure have at least 500
Psig of pressure?
Are the flow rate and delivery pressure of calibration gases
correct?
PPM calibration gas cylinders should be made of aluminum
and not steel.
Are the calibration gas cylinders less than 2 years old?
Calibration Line Check
To test for contaminated lines, you must temporarily bypass
your current calibration line with a clean calibration line (directly
from the calibration gas cylinder to the sensor calibration inlet
port using a flow meter to set the proper flow) and compare the
response with that from the possibly contaminated line. The
best calibration gas to use for this check is o
gas.
Loss / Inadequate DC Voltage to the Analyzer
Measure the Dc voltage to the analog board at TB3, Pins 1
and 2. Pin 1 is positive. Ensure that this voltage is +24 ± 5%.
