    Chapter 4 - Configuration CHAPTER 4 - CONFIGURATION SCOPE The Universal Scale and the Analog Scale do not require any configuration. The DeviceNet scale con- figuration consists of setting the baud rate and node address on a DIP switch which is accessible through an access port on the bottom of the scale.

    Any-Weigh™ Series Bench Scales imal places in the 32 bit integer weight outputs. The value 0 causes these weight outputs to be in floating point format. NOTE: This applies ONLY to the weights as viewed through the I/O (Command) interface. The explicit message interface continues to use 3 decimal place 32 bit inte- ger format only.

  • Page 27: Examples Using The Command Interface

    Chapter 5 - Setup Most of the DeviceNet Scales’ parameters are only 1 byte long, making it possible to write them with a sin- gle command. There are also some 4 byte parameters. To write one of them: Step 1. First write the 2 most significant bytes, using a WRITE command as described above, with 0x27 in the parameter number...

    All controls are accessible. from the underside of the scale. The ANY-WEIGH Analog Scale is calibrated at the factory for 4 mA current output with zero millivolt input and 20 mA output for 15 mV input. In some cases, the transmitter will require a very simple recali- bration to the system in which it is installed.

    Chapter 6 - Calibration volt (of transducer excitation) will be represented by the 4-20 mA output range. The gain can be adjusted from 3 mV input per volt of excitation to as high as 0.8 mV input per volt of exci- tation.
  • Page 34 Any-Weigh™ Series Bench Scales Step 6. Adjust the SPAN for 20 mA (2 V) for full- scale weight. For less than full-scale weight, perform the following steps: Divide: calibration weight/full- scale weight = (F)raction of full scale. Multiply: (F)(16 mA) = 1, the cur- rent caused by the calibration weight.
