  • Page 3: Unpacking And Setup

    Unpacking and Setup: The balance, weighing pans, remote power supply, windscreen (standard on some models) and any op- tional accessories are packed in a foam support to protect them from shock during shipping and han- dling. Save and reuse all packing material for future damage-free shipments.

  • Page 4: Choose The Proper Environment

    Choose the Proper Environment: The environment in which your balance is used is very important. Air movement, temperature changes, vibra- tions, direct sunlight, etc. influences the performance of high precision balances. Therefore, place your balance on a solid, sturdy surface that is free of air currents, vibration and not in direct sunlight. The surface should not be magnetic and should be located away from doors, windows, heaters, air conditioners and fans.

  • Page 5: Connect To An Electrical Outlet

    Note: First plug the round 2.5mm connector into the balance’s rear panel receptacle. Then, plug the power supply into a grounded AC outlet. Note: Scientech recommends that the balance be plugged into an electrical outlet at all times. This insures the balance is always warmed up and ready for use.

  • Page 6: Equipment

    Equipment: Select weights that have a tolerance that is one third or better than the accuracy you require for your application. This way the error of the weight will not dramatically impact the quality of your measurements. The equipment must be of sufficient readability to calibrate or measure the weight or sample under test.

  • Page 7: Front Panel Controls

    Place the weight or sample near the center of the balance pan. A small offset from center can have a pro- nounced effect and introduce undue variation. 3. Take special care not to breathe onto the weight or into the balance chamber. Back away from the instru- ment.

  • Page 8: Dual Range Balances

    Note: Scientech balances are DTE (computer) devices. If communicating to another DTE device (ie computer), a Scientech RS-232 cable, PN10697, or normal null modem cable is required. If you are communicating to a DCE device (printer), a serial cable is required. Scientech offers a serial cable, PN11367, for your convenience.

  • Page 9: Balance Functions And Features

    Balance Func ons and Features: Autocalibration – To Calibrate the balance to an External Weight: This procedure calibrates your balance to an external calibration weight. If your balance has a motorized inter- nal calibration weight it will have a suffix of IW after the model number. Please use the procedure for Autocali- bration to calibrate the balance to a Motorized Internal Calibration Weight.

  • Page 10: Autocalibration-To Calibrate To An Internal Weight

    Autocalibration – To Calibrate the Balance to a Motorized Internal Weight: This procedure is only for balances with the suffix IW after the model number which means a motorized inter- nal calibration weight is installed. Note: Dual range models must be placed in HI range before starting the calibration procedure. Note: For correct calibration weight refer to specification charts in the back of the manual.

    Density Determination: Scientech does not offer a density determination kit nor do you need one to determine density. Density is mass (grams) per unit volume (cubic centimeters). In order to determine density of a solid, place a graduated flask with a known volume of water on the pan of the balance, tare the balance, and then place the solid in the flask of water.

    A security bracket is provided on the rear panel providing a convenient method of securing the balance. Op ons: Below Balance Weighing and Custom Unit of Measure options must be installed at the Scientech factory. Other options, such as a Scientech printer, may be purchased at any time.
