==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=== | |||
