ADJUSTMENT 6
6.4.9 One-point adjustment using the keypad (function CAL1)
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, see “Setting ambient parameters”,
page 61.
1 Check that no error messages are active.
Active error messages influence adjustment. Malfunction messages, see “Error display”,
page 92. (Serial interface) and see “Display of active and undeleted errors (ERR)”,
page 36 (keypad) Error Table see “Error Table”, page 92.
2 Enter the password in menu PAS, see “Entering the password (PAS)”, page 37.
3 Select menu item Cal1. This holds the analog output.
4 Connect the span gas.
5 Enter the known O

value and confirm with Ent.
6 The measured value display blinks.
7 Feed adjustment gas.
8 Wait until the display shows a stable value.
9 Confirm with Ent.
PASS is displayed when the calibration is successful. The device now calculates the new
gain and offset settings and starts to display the new measured value.
10 Press Ent twice. This ends the one-point adjustment.

The reference concentration used determines whether the gain or offset parameter
value is changed.
– Change to the offset value: Oxygen concentration < 10.5% O
2
– Change to the gain value: Oxygen concentration > 10.5% O
