Figure 6: Stripped wire
To insert a wire into a spring terminal,
first strip back the insulation leaving
10 mm of bare wire exposed as
shown in Figure 6.
Using a small flat headed screw-
driver (or similar) fully depress the
orange plunger located above the
hole into which the wire is to be
inserted and insert the wire into the
hole as far as it will go, as shown in
Figure 7.
Release the orange plunger and the
wire is held captive by the connector
(Figure 8).
A gentle tug on the wire will
confirm that it is held firmly.
5.2 Differential/Single-ended
Each analog connector has available 2-inputs that must be connected as a
pair where a differential signal is to be measured. Alternatively, they can be
wired to 2 independent single-ended signals and measured separately.
When the logger is configured to read 2 independent signals in this
way, the polarity inversion of the negative input is automatically compensated
before the readings are processed further.
