Error

Calibrate

The display shows the above message to indicate that the power supply is ready for voltage calibration.

5 Calibrate DAC and select the low voltage calibration point.

30 LEFT

The ‘‘START BITCAL’’ message is displayed for about 3 seconds to indicate that the power supply is ready for DAC calibration. Then it counts down numbers from 30 to 0.

V LO 0.5000 V

Then, the display shows the low voltage calibration point.
