2. In Bluehill3, open Admin > Configuration > Transducers.
3. Move the User Defined transducer from the left hand pane (Available transducer
types) to the right hand pane (Transducers), and enter the details of the fields as follows:
• Transducer configuration: Rename the transducer (e.g 750 mm long travel
extensometer)
• Units group: strain
• Connector: 3 labelled as Strain 1
• Identify transducer using: Resistor codes
• Resistor codes: 0,0
4. Exit Bluehill3 and restart it.
5. Set the gauge length using the calibration bar supplied (see page 3-2).
6. Open the Transducer Settings dialog box of the ‘LVDT’ icon and enter the details of the
fields as follows:
• Transducer configuration As previously named in step 3.
• Full scale Calculated as follows:
Example using a gauge length of 20 mm;
• Gauge Length As set in step 5.
• Cal point Same as Full scale value
7. Click Calibrate. and when calibration is complete, close the dialog box.Open Method
> Measurements
8. Move the ‘User Defined’ transducer to right hand pane and from the Transducer
configuration: drop-down list, select the name given in step 3.
The extensometer is now configured for use in the Bluehill3 test method.
Refer to the Operating Instructions or online help for more details.
As the 2603-084 and 2603-085 extensometers have an identity resistor code of zero, the
software assumes it is a used defined transducer and displays the LVDT symbol in the
STRAIN 1 channel.
