4.4 Manual Calibration
4.4.3 Manual Calibration for Vapor Recovery Applications
1. The measurement system
for this applications includes a
converter, therefore calibration
span gas must contain oxygen
for the converter to work pro-
perly.
2. During channel 1 calibra-
tions, the calibration gas must
go through the converter. The-
refore, before starting calibra-
tions, ensure „Pump 1“ within
the control menu is set to ON.
Note!
„Pump 1“ is used to disable (Off) or enable
(On) the gas ow through the converter!
Recommended specication of calibration
gases:
• Zero gases for both channels:
Nitrogen or air, free of hydrocarbons
• Span gas for channel 1:
CH
4
in air, concentration should be about
90…100 % of measuring range
• Span gas for channel 2:
Suitable hydrocarbons (C
n
H
m
) in air, con-
centration should be about 90…100 % of
measuring range.
Perform the zero and span calibrations fol-
lowing the procedures described in sections
4.4.1 and 4.4.2.
