Testing Specifications

High Voltage: All input and output terminals will withstand 1500 Vac rms to

chassis or instrument ground for one minute with a leakage current not to exceed

25 mA, for all terminals to ground. Input and output circuits are electrically

isolated from each other, from other circuits and from ground.

Surge Withstand Capability: All input and output circuits are protected against

system transients. Units pass all requirements of ANSI/IEEE C.37.90.1-1989

defining surge withstand capability.

Radiated Electromagnetic Withstand Capability: All units are protected against

electromagnetic radiated interference from portable communications transceivers.

Environmental

Temperature Range: Functionality is maintained from -40° to +85° C.

Humidity: Functionality is maintained under 95% relative humidity (non-condensing).

Fungus Resistance: A conformal printed circuit board coating inhibits fungus growth.
