4.5 Operating Environment/Storage:

4.5.1 Operating Temperature: Electrical, electronic, and electromechanical items shall be capable of operating in an ambient temperature of 67 to 79 degrees F without loss of required performance.

4.5.2 Operating Humidity: The equipment shall maintain specified performance in an atmosphere from 20% to 50% relative humidity without loss of required performance.

4.6 Facility Electrical Power and Connections: The Mass Comparator shall be capable of operating on standard 110 V AC 60 Hz electrical power.

4.7 Safety: Documentation will be provided to support the means by which electrical safety considerations have been addressed. The safety of all personnel will be assured in conductive or nonconductive contact with the outside of the equipment, and during the changing of the fuse with the power to the system and its components are turned on. This documentation shall consist of a minimum of a citation of a UL or ANSI identified standard or equivalent United States Standard that the equipment conforms to.

5.0 CONTROLLER REQUIREMENTS:

A laptop controller is required that can efficiently operate under Microsoft Windows 7 Professional operating system.
