Proceed with the calibration by pressing ENTER again. At this time the output voltage
will rise to about 90% of the rating of the supply, and the screen displayed in Figure 5-10
will be displayed.
Figure 5-10
Voltage Calibration 2
In this figure the number 3300 is for example only and will vary with each supply. The
“OK” means the value being read internally is within an acceptable range and the
calibration may proceed. At this time read the output voltage using the volt meter, and
using the numeric keypad enter the correct voltage to five places. Press ENTER when
the correct voltage has been input. A reading of “LOW” instead of “OK” indicates either
too low a resistance in the load or a faulty power supply.
After ENTER of the last step has been pressed, the power supply will automatically
calibrate the overvoltage protection circuits. No user intervention is needed for this step.
When the OVP calibration is complete the display shown in Figure 5-11 will be shown.
At this time pressing ENTER will save the new calibration constants and return the
supply to normal operation. Pressing CANCEL will discard the new calibration
information and return the supply to normal operation.
The calibration is now complete.
