List of parameters:
INTG
GAIN
When you exit analog output mode after modifying the integration
constant, the new value is also used to calculate the display of the
controller.
Scale factors that correspond to the combined choice of the gain and the
counter increment.

OUT (mV) = Measure (unit)
Example: using the Table.
The controller operates in manual mode with a Yincr value of 0.2 and a unit
given in arc-sec. The following values can therefore be read:
We can therefore expect to obtain the following analog values:
• With a gain of 1:
• With a gain of 5:

(F2) Lower value.
(F3) Next highest value.
(F5) Save and Return to analog output mode.
