uncertainties.
10.3 Operation
Using the 2563 Thermistor Module with the 1560 Black Stack is very simple.
The following sections explain the steps for setting up and using the 2563 to
measure with thermistors. For instructions for installing the 2563 Thermistor
Module onto the 1560 see Section 4.1.
10.3.1 Connecting a Thermistor
The 2563 Thermistor Module has ten terminal posts, five each for the two
channels (see Figure 16). The red terminals connect to one side of the sensor.
One sources current and the other senses the voltage. The black terminals con-
nect to the other side of the sensor. One sources current and the other senses the
voltage. The green terminal connects to ground and can be used to ground a
shield wire. Two thermistors can be connected to the 2563 at once.
To connect two-wire thermistors to one channel, connect one wire to both red
terminals and the other wire to both black terminals. If there is a shield or
guard wire connect it to the green terminal.
To connect four-wire thermistors to one channel, connect the wires from one
common pair (wires that are shorted together at the sensor element) to the red
terminals and the wires from the other pair to the black terminals. If there is a
shield or guard wire connect it to the green terminal.
