Process Unit 73 LF - Knick

How to define temperature compensation
Press to select ”TC Test Medium” from the
Parameter Setting menu (opl or adm).
Press to select ”TC Calculation Off”, ”Linear”
or ”EN” (with opt. 392 also ”Ultrapure”) and confirm
with .
If you have selected ”TC Calculation Linear”,
press .
You can now enter the TC of the solution and the
reference temperature using scrolling and cursor
keys (see page 2–5). Confirm your entries with
.
If you have selected ”TC Calculation Ultrapure”
(only with opt. 392), press .
Now you can select the type of impurity and confirm
your choice with .
If one of the above mentioned types of TC correction
has been set, the menu line “Sample Cal” is
displayed.
Here, you can select whether sample calibration is
to be performed with or without TC correction (see
Pg. 6–10).
Current Output
The current output provides an impressed standard
current of 0 to 20 mA or 4 to 20 mA. The output
current can be read out on a secondary display
(see page 2–1).
You can assign the output current to any of the
following variables:
conductivity value
resistivity
measured temperature (C)
concentration (only with options 359, 360, 382)
Output current will be frozen at its last value:
during calibration
during current source function (manual entry)
in the menu “Meas. Point Maintenance”
in the menu “Resistance Measurement”
after the corresponding interface command
