Measurement type (channel-wise)
Click the field to have the available measurement types displayed and select them.
Possible measurement types:
● Voltage ±80 mV
● Resistor (4-wire connection)
● Resistor (3-wire connection)
● Resistor (2-wire connection)
● Thermal resistor (linear, 4-wire connection)
● Thermal resistor (linear, 3-wire connection)
● Thermal resistor (linear, 2-wire connection)
● Thermocouple
With this parameter, you set the measurement type, for example, voltage. For any unused
channels, you must select the
setting. For a disabled channel, the conversion time
and integration time of the channel = 0 s, and the overall cycle time of the device is reduced.
With this parameter, you set the measuring range of the selected measurement type.
Temperature coefficient (for RTD, thermoresistor)
The correction factor for the temperature coefficient (α-value) specifies the extent to which
the resistance of a certain material changes when the temperature is raised by 1 °C.
The α-values conform to EN 60751, GOST 6651, JIS C 1604, and ASTM E-1137.
The temperature coefficient depends on the chemical composition of the material.
