When you measure the output voltage or short current by the multi-meter, please make
sure the value is correct. Otherwise it will cause the calibration failure and let the
output turbulence.
Please make sure that the maximum current of your multi-meter is higher than the
maximum current of the calibrated power supply, otherwise it would damage the
multi-meter.

5.4 Reset to the default calibration settings

In the calibration process, if there is any failure caused by the misreading the voltage value and current
value or any other reason, you can use the Restore to let the power supply return to the state before
calibrating.
Chapter 6 PV1785B_1788 Software

6.1 Introduction

Software PV1785B_1788 is control software for 1785B - 1788 series programmable power supplies. It
