PSU Studer A810

Hi, I need some advice about the revision of my Studer A810.
For the electrical adjustements I measure some difference in the dual output (+/-15V).
With load, at the test points I have -15.62/15.19V, without load measuring on stabilizer card -15.66 en +15.38V. Maximum deviation according manual is 100mV.
Is this something to worry about?
Thank you!
Best,
Martijn
