Maintenance - Calibrate
The calibrate program is used to gas calibrate the analyzer. Gas
calibration should be performed monthly. This procedure will require
the use of the calibration adapter that was included with the unit.
Connect the long end of the hose directly to the gas analyzer and
connect the filter end of the adapter to the Gas bottle. When you
first enter the Calibrate program you will be asked to confirm or
change the gas values to match the bottle of calibration gas you
are using.
The bottle provides a large quantity of gas at a high pressure.
The regulator reduces the flow of gas to the low level required for
calibration. The connection to the analyzer is made in place of the
sample hose.
The ideal calibration gas to be used with the analyzer contains the
following concentrations of gas: Propane - 1,200 PPM, CO - 4.0%,
CO2 - 12.0%, NOx - 1000 PPM. Other concentrations of gas can
be used, but be sure the NOx concentration is above 500 ppm and
less than 3000 ppm.
Use the SELECT and NEXT
buttons to change the gas val-
ues. You will then be asked
to connect the calibration
adapter to the analyzer. See
the picture at the right to see
how to connect the gas bottle
to the analyzer.
