Input connectors
The Multilogger does not have galvanically isolated inputs. For this reason,
only devices that are not connected to any other circuit may be connected
to the inputs of Multilogger. Simplified circuit diagram of inputs is shown in
Appendix 3
.
MiniDIN connector
_______________________________
It is used for connecting the DigiS/M
…
, DigiL/M
…
, Pt1000/M probes
and for external CO
2
probe. Plug properly oriented probe connector to
the input of Multilogger. You can follow the optical key for correct
position. Make sure that the wires, including their shielding, are not
connected to any other conductive parts! Universal MiniDin
connectors are designed for
DigiS/M…, DigiL/M… or Pt1000/M
probes. Conventional (custom) probes with a Pt1000 sensor can also
be connected, however with certain
limitations (see
Appendix 4
). The
input connector marked “
CO
2
”
is not
universal and it is designed for
external CO
2
probe only.
Universal thermocouple connector
___________________
Plug properly oriented connector to the input of Multilogger. The
connector is mechanically coded using a wider pin. Use the white
uncompensated connector for measuring voltage. Make sure that the
wires are not connected to any other conductive parts! Electrical
coupling among thermocouples can cause large measurement errors
or instable values! To obtain correct measurement values, the
Multilogger has to be temperature-stabilized!
