INTRODUCTION
This manual covers Installation and Operation for the Ohaus Dial-O-Gram ®
Balance Model 310 and Cent-O-Gram ® Balance Model 311.
DESCRIPTION
Ohaus Dial-O-Gram ® Balance Model 310 and Cent-O-Gram ® Balance Model 311
are manufactured from high grade precision zinc castings for the base and
precision aluminum castings for the beam. Agate bearings, hardened steel knife
edges, and stainless steel pans ensure a high standard of quality for these
products.
The 3-point base together with the special floating bearing principle and beam
design eliminates the need to have a level adjustment. Zeroing is easily and
quickly achieved by means of a counter balancing knob at the end of the beam.
The balances are intended for use in education, and industry applications. They
produce quick readings due to their damping mechanism. Both balances can
also be used to make specific gravity measurements. Model 310 has two beams,
each with a sliding poise, and a graduated dial and vernier which enables
readings of 0.01 g. Capacity of the Model 310 is 310 grams. Model 311 has four
beams, each with a sliding poise. Capacity of the Model 311 is 311 grams with a
readability of 0.01 g.
