Low Calibration Adjustment
8. Press C4 on the external keyboard to set the Low calibration value.
9. Measure the output voltage. It should read
10. If required, the output voltage can be adjusted to this value by pressing the
following keys. The Pitch/CV output adjustment resolution is about 2 mV
C3 = decrement coarse
D3 = decrement fine
E3 = increment fine
F3 = increment coarse
TIP: You can press and hold an increment or decrement key and (after a
brief delay) the output adjustment will repeat automatically until the key is
released.
Zero Calibration Adjustment
11. Press D4 on the external keyboard to set the Zero calibration value.
12. Measure the output voltage. It should read
13. If required, the output voltage can be adjusted to this value by pressing the
following keys. The Pitch/CV output adjustment resolution is about 2 mV
C3 = decrement coarse
D3 = decrement fine
E3 = increment fine
F3 = increment coarse

E4 Start High Calibration. Target voltage is 6.500 Vdc
D4 Start Zero Calibration. Target voltage is 0.000 Vdc
C4 Start Low Calibration. Target voltage is -2.500 Vdc

High Calibration Adjustment
14. Press E4 on the external keyboard to set the High calibration value.
15. Measure the output voltage. It should read
16. If required, the output voltage can be adjusted to this value by pressing the
following keys. The Pitch/CV output adjustment resolution is about 2 mV
C3 = decrement coarse
D3 = decrement fine
E3 = increment fine
F3 = increment coarse
Saving the PITCH CV Calibration Settings
17. When you are done, you must press C#3 to save your calibration settings.
Note: If you do not do this, your changes will not be saved.
Exiting the PITCH CV Calibration Procedure
18. When you are finished, you must press C#4 to exit the Calibration Mode and
return the MODEL D to normal operation.
19. If you want to do the other calibrations for the oscillators and octave range,
follow the procedures shown on the next pages.
20. If you do not want to do any other calibrations, turn off the MODEL D,
check the internal cables are securely connected, and secure its front panel
assembly back onto the chassis using the 8 screws.
Restoring the default PITCH CV settings
21. If you want to restore the Pitch CV calibration back to its factory settings,
send the SysEx command shown below. (See the previous pages for details
regarding the sending of SysEx messages.)
