Ground
Thermocouple
This instruction measures a thermocouple with a single-ended voltage
measurement and calculates the thermocouple temperature (
°C) for the
thermocouple type selected. The instruction adds the measured voltage to the
voltage calculated for the reference temperature relative to 0
° C, and converts
the combined voltage to temperature in °C.

& Data Type
Enter
Dest Variable
or Array
The Variable in which to store the results of the instruction. When Reps are used the
results are stored in an array with the variable name. An array must be dimensioned to
have elements for all the Reps.
Reps
Constant
The number of repetitions for the measurement or instruction.

The mV200C, mV50C, and mV20C
ranges pull the channel into common
mode range and check for open input
DiffChan
Constant
The differential channel number on which to make the first measurement. When Reps are
used, subsequent measurements will be automatically made on the following channels. If
the channel is entered as a negative number, all reps occur on that channel.
SEChan
Constant
The single-ended channel number on which to make the first measurement. When Reps
are used, subsequent measurements will be automatically made on the following channels.
If the channel is entered as a negative number, all reps occur on that channel.

Variable
The name of the variable that is the reference temperature for the thermocouple
measurements.
