==Possible replacement gas filling==
==Possible replacement gas filling==
For the P6015 non-A version, a replacement for the CFC-114 filling gas that is no longer available is needed.
Several options have been suggested:
===Mineral oil===
Compensation range may be insufficient - see below; tbd
===Low-viscosity silicone===
Dow Corning Xiameter PMX-561 has been suggested ([http://www.reb3.com/pdf/AN108.pdf R.E.Beverly III and associates AN-108, ''Dielectric Replacement in Tektronix P6015 HV Probes'']).  The compensation circuit needs to be adapted to allow for the higher capacitance.
===Butane (lighter gas)===
Dielectric strength may not be sufficient, and obviously the gas is flammable.
===HFC236-FA===
