ADJUSTMENT
6.3.5
Two-point adjustment via the serial interface (command COXY2)
This command starts a two-point adjustment.
Syntax:
COXY2
<cr>
Example:
Two-point adjustment via the serial interface
This adjustment calculates and sets new gain and offset parameter values. A two-point
adjustment uses one gas to adjust the lower limit value of the measuring range and a
different gas to adjust the upper limit value of the measuring range. These can be, for
example, pure nitrogen (0.0% O
2
) and an N
2
/O
2
mixture (for example, 21% O
2
). The
minimum difference between the two span gas concentrations in two-point adjustment
should be at least 4% O
2
. It makes no difference whether the gas is first used for the lower
or upper span.

and confirm with Enter. The analog output can be held
during an online adjustment.

When adjustment conditions (gas pressure, humidity and CO
2
concentration) are
different from the operating conditions of the measuring device, set the ambient
parameters of the measuring device to the adjustment environment for the adjustment
duration. These settings must then be changed back to represent the process
conditions when the TRANSIC111LP is reinstalled in its operating environment. Further
information on setting the ambient parameters of the TRANSIC111LP can be found in
Section 5 of this Manual.
