5. Follow the instructions on page 127 .
Note: If you have a version of the board without the -PBF (lead-free) designator, this
potentiometer is labelled R4.
6. Click Quit when you are finished.
Once you have finished this procedure, continue with “Calibrating the Analog Output
Subsystem” on page 130 .
Using the DT3034 Calibration Utility
Note: After switching the power on, allow 15 minutes for the board to warm up before
calibrating the analog I/O subsystems.
To start the DT3034 Calibration Utility, do the following:
1. Click Start from the Task Bar.
2. Browse to Programs | Data Translation, Inc| Calibration|DT3034 Calibration Utility .
The main menu appears.
Once the DT3034 Calibration Utility is running and you have connected the required
calibration signals to the DT740 screw terminal panel, you can calibrate the analog input
circuitry of the DT3034 board either automatically or manually; auto-calibration is the easiest
to use and is the recommended calibration method.
This section describes these calibration methods.
Using the Auto-Calibration Procedure
Auto-calibration is the easiest to use and is the recommended calibration method.
Note: If you want to manually calibrate the bipolar and unipolar ranges instead of
auto-calibrating them, refer to “Using the Manual Calibration Procedure” on page 128 .
To calibrate the analog input subsystem, do the following:
1. From the main menu of the DT3034 Calibration Utility, click Configure , and then Board .
2. Select the name of the DT3034 board to configure from the combo box, and then click OK .
3. From the main menu of the DT3034 Calibration Utility, click Calibrate , and then A/D .
