  • Page 3 - Use greatly impacting human lives and assets, such as medical devices, transport devices entertainment devices, and safety devices. Warning on installation ● Do not disassemble, repair, or modify the F701-P. Doing so may cause a fire or an electric shock. ● Do not install in the following environments.
  • Page 4 ● For turning on/off the power, be sure to keep intervals of 5 seconds or more. ● After power-on, make sure to warm up the F701-P for at least 30 minutes or more before use. ● If the F701-P is not used by the specified method, its protective performance may be impaired.
  • Page 5 Caution during transportation ● When the F701-P is shipped, spacers made of corrugated cardboard are used as cushioning materials. Though it is factory-designed so that shocks can sufficiently be absorbed, breakage may result if shocks are applied when the spacers are reused for transportation.

    4-1. Span calibration Calibration is performed for matching the F701-P to a load cell. For example, it is work to adjust so that the F701-P accurately displays 100.00kg when an actual load (or weight) of 100kg is applied to the load cell (balance section) of the weighing apparatus to which the F701-P is connected. This operation is called Span Calibration.

    ■Calibration error display Chapter (Calibration error) The initial tare exceeds the zero calibration range of the F701-P. Check the load cell for unnecessary load. If " " is displayed under a normal load, there is a need to connect resistance between the +EXC and -SIG terminals of the load cell and redo zero calibration after shifting the zero point.
