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.
