5.4.4.11 Scaling menu
The various inputs for temperature measurement are scaled in this menu.
A Pt100 input for directly connecting a Pt100 sensor (e.g. type 2392-V001) is available in addition to a linear
voltage/current input for connecting a temperature transmitter (e.g. pyrometer).
The following entries are possible:
[F3] key (HOME):
This effects a return to the main menu.
[F4] key (RETUrn):
This effects a return to the parameter menu.
The [
↑
] and [
↓
] cursor keys are used to select the various inputs.
The selected parameter is displayed inversely.
The [POS1] key is used to select the 1st parameter in the window.
The [END] key is used to select the last parameter in the window.
Pressing the [F 1] key (SEL) invokes the menu for scaling the selected input.
Scaling Pt100 input
This menu is used to enter the coefficients for the Pt100 curve in the range
≥
100
Ω
(i.e. only positive
temperatures).
[F3] key (HOME): This effects a return to the main menu.
[F4] key (RETUrn): This effects a return to the scaling main menu.
