6.4.7
One-point adjustment via the serial interface
One-point adjustment: Either the gain or offset value of the measurement is changed.
When the O
2
concentration of the span gas is >10.5% O
2
, the one-point adjustment
returns a new gain value otherwise a new offset value.
6.4.8
One-point adjustment via the serial interface (command COXY1)
This command performs a one-point adjustment. While the program waits for the input of
the O
2
concentration, command
R
can be used to trigger continuous output of the current
O
2
measured value. Pressing
Enter
once (on the computer keyboard) terminates Print
mode. Pressing
Esc
once cancels the adjustment. Syntax:
COXY1
<cr>
Example:
One-point adjustment via the serial interface
This adjustment calculates and sets a new gain or offset parameter value (depending on
the reference concentration used).

Outputs (analog, relay, POLL/Run and MT300) frozen
This command holds the current values of all outputs. This command should be used
during online adjustment so that measured value changes do not disturb process control.
This step can be omitted when the device to be adjusted has been removed from the
process or is separated from process control.
When adjustment conditions (gas pressure, humidity and CO
2
concentration) are different
from the normal 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.
