Kapanadze and other FE discussion

[r2fpl]

IMPORTANT ANNOUNCEMENT:


I have found out today that KAPANADZE DIED FROM COVID APPROXIMATELY ONE YEAR AGO.
R.I.P.


I am trying to contact his friends to see if anyone knows the secret.

Is this an associate of Kapanadze ?:

How do I to make electrostatic attenuator ?
As an ordinary voltage divider with resistors like, but using infinite resistance ?
It will be used for working with electrostatic voltmeter together.

Another method  is phototransistor and diode LED in chip-  inexpensive and reliable. - tansoptor.
PC817X Series contains an IRED optically coupled to a phototransistor.

here is an example of optical separation for stability of measurement:
HI-4417 Holaday
Here is manual:

I have it  too.
The device was in  production since 1999.
Originally it cost good Mercedes but now you can buy  only for  few thousands .
