6.7 Calibration Procedures
The following section includes the manual and software assisted adjustments that
can be made in the Wavemaster system
6.7.1 System Power Supply Calibration Procedure
• Measure the power supply voltages as shown in the table below. If any are
found to be outside of their specifications proceed with the remainder of this
procedure to adjust them.
• The power supply will need to be removed from the unit and have the cables
connected to the main acquisition card for a load.
• +5V should be present on pin 1 of J6. This +5V must be connected to J6 pin 4
to enable the supply outputs. Once connected, the outputs should all reach
their approximate intended output voltage.
• Measure each voltage as shown in the table below and adjust the
potentiometers accessible through the cover as shown until each voltage is
within its specified range.
The following table lists the nominal, min and max voltages for the outputs from the main
power supply.
Nominal Output

+3.3V +2%
+5.05V +3%
-3.3V +2%
+12V +2%
-12V +2%
-5.05V +3%
+24V +2%
