0% = CO CO-value at 0% analog input value
100% = CO CO-value at 100% analog-input value.
H2 [%] H2 value which is used for the calculation of the process values
AnaIn H2 To take the H2-value of an analyzer a ext. analog input can be used. In this case the
scaling must be set in the next two columns. With AnaIn H2 = ---- the H2 has to be
set manually or by a process leading system
0% = H2 H2-value at 0% analog input value
100% = H2 H2-Wert at 100% analog input value.
Foil
In order to calculate automatically the accurate correction-factor for a foil-measurement, PT50 requires
two information:
1. The measured Cp at the time of the foil-measurement.
2. determination of the Cp-value of the foil
The first two lines in the submenu foil serve for the setting of this information.
Foil standby/ready !
When the foil is extracted during a foil-measurement out of the furnace, the PT 50 must be informed by
setting this line to “foil ready!”. The PT50 remembers the corresponding Cp-value in order to use it for
the calculation of the correction-factor.
Foil-value
The Cp-value from the analysis has to be entered here. The enter-function can only be called if PT50
was told before that a foil has been extracted. After end of the input, the PT50 calculates the new cor-
rection-factor.
KF
Shows the last entered or automatically calculated Cp-correction-factor. Hint: the correction-factor can
be set manually in the submenu „correction “.
Correction
If for an input an offset <> 0 is parameterized, then the mark OFFSET! appears in the overview-
windows beside the corresponding value. Through pointing to this mark the value of the offsets will be
shown.
US-Offset
corrective offset for the US-input in mV
TCS-Offset
corrective offset for the TCS-input in °C
TC2-Offset
corrective offset for the TC2-input in °C
