Connect

Temperature measurement connections

You can use Channel 1 of the 2182A to make temperature

measurements. The following figure shows connections

using the internal reference junction. The thermocouple wires

must be soldered directly to the CHANNEL connector.

The following figure shows temperature-only connections

using an ice bath as a simulated reference junction. The

connection points for the input cable and the thermocouple

wires are immersed in the ice bath.
