Setup dialog
This dialog displays the cold junction temperatures of analog inputs 1 to 4 ("Channel 1" to
"Channel 4"). The cold junction temperature is required for compensating the influence of the
ambient temperature for thermocouples.
The cold junction temperature either relates to the measured value of the relevant internal
Pt100 temperature probe (temperature at the terminals) or a fixed temperature value (specified
manually).
The measured value of a fifth Pt100 temperature probe ("Internal") is also displayed (tempera-
ture inside the case).
Initially, the values are determined once and are displayed. To display them again, click the
"Read out" button.
