  • Page 8: Getting To Know Your Balance

    Voyager Balance. 1.1 Introduction Thank you for deciding to purchase a Voyager Balance from Ohaus. Thanks to a new modular design, your Voyager Balance lets you adapt the balance to your changing needs. Remote displays, upgraded displays which can be table, wall or tower mounted are available as accessories.

  • Page 9: Selecting The Location

    2.2 Selecting the Location 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.

  • Page 10: Installing Cover Plate And Pan

    2.4 Installing Cover Plate and Pan Balances in the range of 62g to 410g are shipped with the pan and the protective cover plate not installed. On balances equipped with a draft shield, slide open the side door and place the cover plate into position. Then, insert the pan into the center hole which is the measuring transducer.

  • Page 25: Differential Weighing

    3.10 Differential Weighing Differential weighing stores tare and weight values so a sample can be dried and the difference calculated at a later time. Up to 100 samples can be stored. samples can be added to the applications library. Batch and individual samples can be accommodated.The features in the Voyager balance for differential weighing include: RECALL - When selected, brings up previously stored library names associated with each sample.

Initial Weighing First, the container is tared and stored, then the product DIFF WEIGHING - - NAME -- SAMPLE 1 is intially weighed in the container and stored for each 100% sample. A name is given to the samples which is stored TARE WT= 19.09 in the balance.

  • Page 27: Formulation

    3.11 Formulation The Voyager balance can store between 200 minimum and 500 formulations limited only by the memory capacity of the resident library. Each formulation can be named and have up to 10 components specified and identified by name. Once the formulations are stored in the balance library, they may be recalled and used at any time. Each component of a given formulation can be specified as to its weight or percentage.

  • Page 198 Four methods of density determinations can be made with the Voyager balance. These are: solids more dense than water, solids less dense than water, porous material (impregnated with oil), and liquid density. A Density Determina- tion Kit Part Number 470007-010 is specifically designed to be used with Ohaus Analytical Voyager balances.
  • Page 199 Balance modes 6.9.2 Solid density determinations for items more dense than water The density Q is the quotient of the mass m and the volume V. Q = m Density determinations are performed by using Archimedes’ principle. This principle states that every solid body immersed in a fluid loses weight by an amount equal to that of the fluid it displaces.
