Thermocouple Sensor Type - Delphin Expert Logger Manual

Expert Logger
Here you can select the measuring range to be used for individual sensor
types. Depending on the sensor version only a limited range may be per-
missible. Refer to the sensor's technical data. The default is always the
sensor's maximum possible measuring range. The channel receives the
status 'Measurement range overrun/underrun' for measurements not
within the range. Channel status values are available in
itoring.
Unit
Select the unit of measurement in which the temperature is to be dis-
played. Conversion is performed automatically within the device.

Connection
Indicate here how the sensor has been connected (the diagram displays
the selected wiring):

ulting voltage drop across the circuits can lead to more substantial meas-
urement errors (cable resistance is factored into the measurement).

and/or longer supply lines. The loss of feed lines does not matter because
the device has a high-ohm input resistance (no voltage drop on the line
feeds) and the voltage drop (the measurement value) can be measured
directly at the sensor.
