Also note that channel voltage differential reduces the maximum measurement capability of
Channel 2. Normally, Channel 2 can measure up to 12V. However, a 2V differential reduces the
maximum measurement capability of Channel 2 to 10V. In
Channel 2 will cause an overflow condition.

A. Typical Measurement Configuration

Temperature only connections

Channel 1 of the Model 2182 can be used to make temperature measurements.
shows connections using the internal reference junction. Keep in mind that the thermocouple
wires must be soldered directly to a LEMO connector as previously explained.
