Testing the Transducer
Once the transducer is connected, it can be tested using LabChart or
Scope. Looking at the GP Amp dialog, you can see the output from the
transducer as you change the force or load on it. You may have to
adjust the range of the GP Amp to get a good response. If there
appears to be no response from the transducer, recheck the wiring
against the diagrams for the appropriate transducer and the
manufacturer’s instructions. If everything seems to be in order, the
joints are soldered properly and so on, and there is still no response,
contact your ADInstruments representative for help.
Powered Signal Sources
To connect transducers that require some form of power supply to the
GP Amp, first read this section carefully. The requirements of the
transducer should be determined before attempting to connect it up.
To adapt a transducer for use with the GP Amp, you need to:
• set the excitation voltage for the transducer
• wire the transducer to use the eight-pin DIN plug.
You will also need this equipment:
• a soldering iron and resin-cored solder (only resin-cored solder!)
• an eight-pin DIN-style male plug with 45-degree pin spacing (one
is supplied with your GP Amp)
• common E12 resistors: 0.25 or 0.125 Watt, 2% or 1% metal film.
