”C2") source current to the probe. The middle two terminals (“P1" and ”P2")
sense the voltage on the probe. Figure 16 on page 116 shows how to connect a
probe to the input. If the probe has a shield it may be connected to the green
“Guard” connector..
11.3.2 Setup
To make temperature measurements using your probe with the scanner you
must set up the following:
1. Make sure all of the connections are properly set up as explained in Sec-
tion 11.3.1. Select the channel of the probe you want to measure by
pressing the corresponding channel select button above the channel’s in-
put terminals.
2. Set up the correct reference, current, conversion algorithm, and conver-
sion coefficients as explained in the “Setup” section of the 1590 manual.
Other probes may be connected to other channels of the scanner and set
up in the same way.
3. The 1590 should now be able to measure temperature accurately through
the scanner. The 1590 can be programmed to automatically switch be-
tween the channels as explained in Section 11.5.1 below.
