The accuracy specifications apply within the recommended operating temperature range. Accuracy limits
are increased by a factor of the temperature coefficient outside this range.

Short-term accuracy includes nonlinearity and noise uncertainties. It does not include drift or calibration
uncertainties.

Operation
Using the 2560/2567 SPRT Module with the 1560
Black Stack
is very simple.
The following sections explain the steps for setting up and using the 2560/2567
to measure with SPRTs. For instructions for installing the 2560/2567 SPRT
Module onto the 1560 see Section 4.1.
7.3.1
Connecting a Probe
The 2560/2567 SPRT Module has ten patented DWF connectors (U.S. Patent
number 5,964,625) posts, five each for the two channels (see Figure 13). The
red terminals connect to one side of the sensor. One sources current and the
other senses the voltage. The black terminals connect to the other side of the
sensor. One sources current and the other senses the voltage. The green termi-
nal connects to ground and can be used to ground a shield wire. Two probes
can be connected to the 2560/2567 at once.
To connect two-wire probes to one channel, connect one wire to both red termi-
nals 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 probes to one channel, connect the wires from one com-
mon pair (wires that are shorted together at the sensor element) to the red ter-
