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.
