7.4.3.3 Zero&Span All Calibration
7.4.3 Advanced Calibration
Before selecting any further line
make sure the required calibra-
tion gas is applied!
Supply all calibration gases with
the same ow as the sample gas
(recommeded approx. 1 l/min),
pressureless and utilizing the
correct gas fitting (
sect.
3-4).
Make sure the calibration purge
time is set to a value ensuring the
measuring cell is lled properly
with the related calibration gas
after the valve has opened!
Ensure the warmup time after
switching on has elapsed!
Warmup time is 15 to 50 minutes
depending on installed measu-
ring system and conguration!
To start a ZERO & SPAN calibration for ALL
channels select the 5

Advanced Calibration..
Starting from the MEASUREMENT SCREEN
press enter to open the MAIN MENU and enter
CONTROL - ADVANCED CALIBRATION.
Notes!
Single channel analyzers show the same
menu, with the restriction, that the term `all`
relates to the single channel only!
This procedure is a combination of the two
described before, with an important deviation:
If a selected zero gas valve is also assigned
span gas valve for an already zeroed chan-
nel, this channel is spanned, while others are
zeroed in parallel (
Fig. 7-6 on 7-28 for a
procedure ow diagram).
