Application Notes
The ESU15 must be operated in an inverted position. When operating above 10 kV P.I.V., cooling must be used to maintain a condensed mercury temperature below 60°C (40°C recommended). On first use, the filament must run for 15 minutes before applying H.T. Thereafter, a delay of at least 60 seconds is required before applying H.T.
