Data Logger Connections; Celia Isolated Logger; Data Logger Configured For Contact Closure; Bi-Directional Data Logger - ABB Kent-Taylor AquaProbe Installation Manual

4.4 Data Logger Connections – Figs. 4.2 to 4.5
If required, the transmitter may be connected to a data logger
using suitable cables – see Section 8.1. Additional connection
details are shown in Table 4.1 (previous page).
Caution. When connecting to remote receiving
equipment take care to ensure that large earth currents
are prevented as a result of the common zero volt
connections. Failure to observe this precaution may result
in inaccurate or unreliable operation.
