Calibrating temperature sensors with resistors
Perform a cold start as described under “Calibrating temperature sensors with resistors”
in Chapter 7 Repair and adjustment.
Calibrating a temperature sensor - with ice bath and oil bath
Perform a cold start as described under “Calibrating temperature sensors with ice bath
and oil bath” in Chapter 7 Repair and adjustment.
Measuring conductivity in a monitoring system
Conductivity is measured with equipment from Hauser.
This may only be done by authorized personnel.
Function in washing process
The conductivity meter monitors the quality of the water in the disinfection phase, inde -
pendently of the process control.
If the conductivity at the end of the disinfection phase is higher than the preset value,
alarm F13 is generated.
Measuring range
The normal measuring range is 0-20 µ S/ cm
Calibrating the conductivity equipment
See manual: Liquisys CLM 223, from Hauser.
The conductivity equipment is calibrated at the factory by specifying the exact cell con -
stant; see below.

7.2 Default
7.3 Set SP1 Limit 15 µ S/ cm*
Set Hi= Max. contact
Rest default
*The user chooses the value during process validation.
