 Type 10 floating EHT


The Type 10 Floating Low Voltage Supply is primarily intended to facilitate laboratory leakage current measurements of screened cable with the sheath at earth potential in conjunction with a Picoammeter (whose case, together with associated recorder outputs etc),is also at earth potential) measuring insulation resistance up to 1015Ω.

A front panel switch is provided to enable the Lo terminal to be connected to CASE when the instrument becomes a conventional low voltage supply unit. The voltage is set by a 0 - 10V 10-turn potentiometer. A digital panel meter indicates the voltage appearing across the output terminals.
