Why is there a difference between the output voltage set value and the displayed voltage value in PWR-01 series?

The voltage display has a display accuracy of ± (0.2 % of reading + 5 digits).
*The reading refers to the output voltage value.
If the voltage display is not within the specified accuracy, calibration is required. Please calibrate according to the procedure described in the user’s manual.
If calibration does not resolve the issue, please contact your Kikusui distributor or agent.
