5.3.7 Calibration when connected with analog signal

As soon as a sensor is connected with an analog com-
munication, only rescaling of the sensor output is avai-
lable.
The procedures can be performed the same way as
with amperometric sensors:
1. Slope correction
2. Offset correction
These procedures do not replace a real calibration of
an optical sensor.
Before installing the sensor in a fermenter a one point
air calibration (see chapter 5.3.2) should be perfor-
med using iSense Asset Suite or iSenseLight or a digi-
tal transmitter.
A two point calibration (see 5.3.6) should be perfor-
med after each OptoCap replacement and depending
on the process stress after 5 to 10 batches.

5.3.8 Reset to factory calibration

In case of a wrong calibration of an optical sensor, e.g.
by using wrong calibration values during slope or pro-
cess calibration, a new 2-point calibration is neces-
sary. If it is not possible to perform a good 2-point ca-
libration a reset of the calibration data is possible
followed by a good 1 point air calibration (see instruc-
tion manual for the transmitter).

Autoclaving of the InPro 6880 i sensor shaft

Attention! Only the sensor shaft with the installed
OptoCap is autoclavable. The sensor head has to be
removed before autoclaving.
Prior to autoclaving, the maintenance cap has to
be screwed on the sensor shaft to protect the fibre
optics.
If the sensor head is separated from the sensor shaft,
all connectors have to be protected with the enclosed
caps. Soiling of the fibre optics may result in detection
errors.
Before assembling, all connectors have to be checked
for soiling.
