Operation
3.2
The AquaXact 1688 uses state-of-the-art microelectronics to provide a miniature full
functioning transmitter. The user should consider the following precautions when using any
sensitive electronic device:
Do not install the unit near heat sources such as radiators or air ducts.
Do not install the unit in places subject to extreme mechanical vibration
or shock.
Observe the appropriate electrical safety codes and regulations.
Electromagnetic compatibility considerations
3.3
The AquaXact 1688 has been designed and verified by testing to meet the requirements of
the EU EMC Directive 2014/30/EU, for Industrial, Scientific & Medical equipment. The
sensor and the 4-20 mA loop are electrically connected, however they are isolated from
the AquaXact 1688 housing and sample cell fitting threads. Please consider the following
electromagnetic interference issues during installation:
In order to provide an acceptable noise environment for the AquaXact 1688 or any
other digital equipment in the proximity of switching inductive loads, it is recommended
that there be varistors placed across the inductors to keep down the high voltage spikes
during transitions.
AC power wiring should be routed as far away from the AquaXact 1688 and its wiring
as practical.
