Calibration
1. In the calibration window: press F3/
Start
.
2. Enter the temperature to be simulated There are two different
strategies on how to set the temperature:
• Adjust the simulated value until the reading of the indi-
cator/recorder is exactly the same as the default output
value for the current calibration point. This method is
useful when calibrating analog indicators/recorders and
the input signal can be fine adjusted.
• Do not adjust the simulated value, but enter the actual
reading as the output value. This method suits indica-
tors with digital display. It is also handy when calibrat-
ing other types of indicators/recorders with an input
signal that do not support fine adjustment (e.g. pres-
sure indicators).
3. Accept the point using F3/

4. Proceed to next calibration point (step 2) if applicable. When
the calibration run is ready, save or reject the results as de-
scribed in chapter A Calibration Procedure Using MC4 on
page 130.
5. Either do another calibration run, adjust the instrument or end
the calibration by selecting F1/

Hint!
These instructions can be adapted for any kind of indicator/recorder.
Change the input signal connections/settings according to the in-
strument's input signal.
When calibrating a temperature instrument with a detachable sensor
(the input signal is simulated with MC4), use this example as the
source for the input signal part.
You may set the display resolution for the entered indication/reading
in the window that opens by pressing F1/
