If scope don´t meassure nothing with shorted inputs, it usually means it's ok.
Think that this scope has isolated gnd and it has more noise when then are not connected

Thank you harrimansat
so, it means, that it has minimum 40mV error ?
harrimansat:
no, if you connect low, medium generator or resistor noise goes away. In high impeance meassurements noise is normal. For that with the probe you have less noise

There is another one question
it's generally considered, that the emission of the led used in photocouplers will degrade over time, 50% degradation over 5years. Mine is manufactured in 1997.
Have you any plans to change them ? Are they the same as in THS720 (HCNR201-300E) ?
harrimansat:
If you don´t have "Cal error, DC balance" I think it is not necessary to touch them. If your scope pass SPC optos are within tolerance

hello I have read this post and I must say that it is very interesting.
i wanted to make a request if someone can help me. i have a ths710a. i wanted to buy a P5102 HV probe but looking for it i saw that they have very high prices even if used. since it is passive I thought I would try to do it at home. does anyone of you know how the resistances of the divider 1/10 inside are configured?
from the datasheet it is understood that the total resistance is 5Mohm but it is not clear if there is a resistive part on the ground terminal.
thank you very much to those who can help me.
Greetings
