Operation
Powering the transducer
To power the transducer a supply voltage of 12-32VDC is required with a minimum current of
1 amp (to supply peak start-up current). If a Transducer Display ETD is used the ETD will
provide power for the transducer. If a Transducer Signal Breakout Unit is used the power
supply should be plugged into the DC jack on the box. If a Digital Adaptor Lead is used the
power supply should be plugged into the DC jack on the lead.
If a Transducer Display ETD, Transducer Signal Breakout Unit or a Digital Adaptor Lead is
not used, then the power supply can be provided by using either the 2.5m Analog or Digital
Lead’s 15 way ‘D’ type connector with a supply voltage of 12-32VDC on Pin 1 and Ground on
Pin 2.
Note: It is imperative that the voltage does not drop below 12V at any stage.
Using the transducer
1. Switch on the RWT series transducer by ensuring power is supplied.
2. Allow the transducer to carry out its Built In Test (BIT) procedure. Refer to the Built In
Test section for further details.
3. Allow five minutes for the equipment to reach thermal equilibrium before making any
measurements.
4. Zero the transducer, refer to the Zeroing the transducer section.
5. The transducer is ready for use, examples of different ways to extract data can be
found in the Examples of reading/collecting data section.
CAUTION
Only provide power through either the Analog or Digital lead.
Do NOT provide power through both leads simultaneously.
