10. Adjustments
Additionally to the ecom-J2KN
pro
functions described previously,
various adjustments can be made in the instrument.
From the main menu select the sub-
menu "Adjustments" and confirm with
<OK>. A selection of modifiable param-
eters, adjustable according to the appli-
cation, is displayed.
Place the cursor on the desired line and
press <OK> to call up or modify the
adjustment.
The modifiable parameters are:
Re-Calibration (Start with <OK>):
-Start of a calibration phase to set new zero-point for the sensors
Unit (adjustment with cursor keys):
-Calculation of gas concentrations in:
-ppm = volume concentration (parts per million)
-mg/m
3
= mass concentration per volume unit
-mg/kWh (undiluted) = mass concentration per power unit
-mg/MJ (undiluted) = mass concentration per power unit
-ppm (undiluted) = volume concentration (parts per million)
-mg/m

(undiluted) = mass concentration per volume unit
Undiluted:
-Conversion of the gas concentration on selected reference oxygen:
-mg/kWh and mg/MJ are always calculated on 0% O
