In the menu "Primary variable parameters" you will find the parameters that the CLD analyzer module will use to calculate its primary variables internal. Besides, you can change to the submenu "Calibration Factors", where you can set up manual the factors for zero/span calibration of the ranges.

Set up parameters:

¨Select the line of variables you want or the menu line "Calibration factors..." with the ↓ -key or the − -key.

¨Select the variable or change to the submenu "Calibration Factors" with the ENTER key or the → -key.

¨Select any digit with the ← -key or the → -key and adjust a new value with the − -key or the ↓ -key

resp. select the whole parameter with the − -key or the ↓ -key.

¨Confirm the new value with the ENTER key or cancel and go back to the last value with the F2 key.

Line of variables "Barometric pressure compensation":

Barometric pressure compensation may be enabled if another analyzer has a pressure measurement device, and is set to report its reading.
