The bottom connector houses the sensor input and digital input connections. Two
separate connectors are used, separated by a blanking plug. A 9 way connector is
provided for the sensor input and a 4 way connector for the digital inputs.

SENSOR INPUT CONNECTIONS
The MOD53 has been designed with the flexibility 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.
