    ? Analog output Two modes are available: To convert the specified weight value digits to voltage, and to convert the value, in the range from zero to the weighing capacity, to voltage. Output voltage range selection: Using the slide switch located on the option panel, the output voltage range can be switched between 0-1 V and 0.2-1V.

  • Page 6: Function Table

    2. FUNCTION TABLE The function table reads or rewrites the parameters that are stored in the balance. When GX-04 or GX-06 is used, set the function table to specify the balance performance. These parameters are maintained in non-volatile memory, even if the AC adapter is removed. 2-1 Structure and Sequence of the Function Table The function table menu consists of two layers.
