ESI engineering bulletin no.24 (Calibration of a KV divider)

[lowimpedance]

 Seeing the recent ESI KV dekapot 'internal photo' post, prompted me to finally scan these OLD ESI egineering bulletins I had, for the reference of all you metrologists out there. (not sure if these allready exist somewhere else, a quick search gave no results as such)
here they are ;

Thanks for uploading those, I will download those to my computer later. Read them on my phone.

Although I probably won't know what it means, it's still great to have. Thank you!!
