CONDITIONS

This document contains specifications and supplemental information for the Model 2290-10 High Voltage
Power Supply. Specifications are the standards against which the Model 2290-10 is tested. Upon leaving
the factory, the Model 2290-10 meets these specifications. Characteristics, supplemental characteristics,
and typical values are not warranted, apply at 23 °C ± 5 °C, < 70% relative humidity, and are provided
solely as useful information.
