One-point adjustment using the keypad (function CAL1)
When adjustment conditions (gas pressure, humidity and CO

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”,
