Observe the following points when connecting the probes to the
data logger and to the measurement points:
Observe poles of plug.
Insert the plugs firmly into the connections to guarantee that
they are properly in place. Force should not be used.
Ensure that the plugs are firmly attached to the data logger or
that the connections are in place with a blind plug.
Ensure that the probe is positioned properly to avoid disturbing
influences on the measurement.

False connection!
Electric shock! Damage to data logger!
Do not apply electrical signal to cable and avoid contact with live parts.
Only one potential-free contact should be connected.
