DESCRIPTIONDESCRIPTION
DESCRIPTION
The Ohaus ANALYTICAL Plus Series balances are high precision weighing instru-
ments, designed to be versatile, accurate, easy to operate and will provide years of
service with virtually no maintenance. The Analytical Plus series is constructed using
a die-cast aluminum base finished with a durable corrosion resistant epoxy powder
paint. The weighing area is protected from air currents by a draft shield. It contains
solid-state precision electronics PC boards, and a seven and a half, 0.5 inch digit,
VacuumFluorescentdisplay. Eachbalanceoperatesthroughaseriesofmenuswhich
enhances operation. A built in lockswitch prevents preset settings from being
changed.

Environment
The balance should always be used in an environment which is free from excessive
air currents, corrosives, vibration, and temperature or humidity extremes. These
factors will affect displayed weight readings.
DO NOT install the balance:
•next to open windows or doors causing drafts or rapid temperature changes.
•near air conditioning or heat vents.
•near vibrating, rotating or reciprocating equipment.
•near magnetic fields or devices that
may generate magnetic fields (i.e.
motors, alternators, etc.)
•on an unlevel work surface.
Install the balance in the location where it
will be used before proceeding.
