Connecting Voltage Inputs; Connecting Voltage Inputs To Thermocouple Channels - Data Translation TEMPpoint DT9871U User Manual

Connecting Voltage Inputs

The way you connect voltage inputs depends on the channel type you are using. This section
describes how to connect voltage inputs to thermocouple input channels, RTD input channels,
and high voltage input channels.

Connecting Voltage Inputs to Thermocouple Channels

Figure 12 shows how to connect a differential voltage input to a thermocouple input channel
on the DT9871U, DT9871, or DT9874 instrument.
Note: On the standard DT9874 instrument, channels 0 to 15 correspond to the thermocouple
input channels.
