SENSOR INPUT CONNECTIONS
The MOD53 has been designed to accept a wide variety of both Galvanic and
Polargraphic Dissolved Oxygen probes. Parameters such as membrane
correction, bias voltage and temperature sensor type can be easily programmed
into the instrument. It will be necessary to identify the sensor type e.g. Galvanic or
Polargraphic, and the temperature sensor type e.g. PT1000 or thermistor.

SENSOR TYPES
The following figures give the connection details of the most commonly used LTH
cable types. Do not use any other type of cable than those recommended by LTH
or the sensor manufacturer to extend the sensor / instrument distance.
The outer screen/shield should be connected to the centre Earth Stud.
