DESCRIPTIONDESCRIPTION
DESCRIPTIONDESCRIPTION
DESCRIPTION
Ohaus Scale Bases are available in three types of construction and are ruggedly
built with overload protection to take the rough handling encountered in an
industrial environment, yet remain highly precise. Each type is available with
platform sizes of 12" x 12", 18" x 18" and 24" x 24". Models with a P suffix are
constructed with steel platforms, painted black. Models with an S suffix have
stainless steel platforms. The 12" x 12" frames used on Models with P and S
suffixesarepaintedaluminum. The 18" x 18"and24"x24" frames on Modelswith
PandSsuffixesarepaintedsteel. ModelswithanASsuffixareconstructedentirely
ofstainless steeland are suitable for washdownapplications. The loadcells used
inall Ohaus ScaleBases aremade of aluminumand are of a singlepoint, bending
beam design. These scale bases are designed to interface with Ohaus electronic
indicators and work with other compatible indicators as well.

LevelingtheScaleBase
1. Placethe Scale Base in theintended uselocation on a stable, levelsurface.
2. Remove the Platform from the top of the Scale Base to expose the circular
Spirt Level mounted in the top of the frame. See illustrations on page 6.
3. If the bubble is not centered in the scribed circle of the Spirit Level, loosen
the Locking Nuts and adjust the Leveling Feet, either by hand or using an
open ended wrench, until the bubble is centered.
NOTENOTE
NOTENOTE
NOTE: Ohaus Scale Bases are equipped with Leveling Feet which have provi-
sions for using a wrench. This allows the Scale Base to be leveled without raising
it to gain access to the Leveling Feet.
4. Tighten the Locking Nuts and replace the Platform.

CARE AND MAINTENANCE
To keep the Ohaus Scale Base operating properly, it should be kept free from
foreignmaterials. If necessary, acloth dampened withwater and amild detergent
may be used to clean models with a P or S suffix. Models with an AS suffix may
be washed down with a hose. Wipe the unit dry with a soft cloth.
