Calibrating a DT330 Series Board
Once the DT330 Series Calibration Utility is running and you have connected the required
calibration signals to the STP68 or STP68-DIN screw terminal panel, do the following to
calibrate the analog output subsystem of the DT331, DT332, DT333, or DT334 board:
1. From the main menu of the DT330 Series Calibration Utility, click Configure , then Board .
2. Select the name of the board to calibrate from the combo box, and then click OK .
3. From the main menu of the DT330 Series Calibration Utility, click Calibrate.
4. Select DAC0 .
5. Click the increment or decrement arrows in the Manual Adjustment box until the display
reads 0 V (within 0.0005 V).
6. Select +FS and verify that the display reads +9.9997 V (within ±4.5 mV) for the DT333 and
DT334 boards and +9.995 V (within ±15 mV) for the DT331 and DT332 boards.
7. In the D/A box, select the next DAC to calibrate.
8. Repeat steps 5 to 7 until all the DACs on the board are calibrated.
9. Click Quit when you are finished calibrating the analog output circuitry.
Once you have finished this procedure, the analog output circuitry is calibrated. To close the
calibration utility, click the close box in the upper, right corner of the window.
