  • Page 10 The Counter and Scale Meter are capable of supplying more than 1 measurement value (or “Item”) with each reading, as selected in “Ser 3”. In the counter, there can be up to 3 Items plus a Peak value, depending on the selected Function. The scale meter can transmit Net, Gross and Peak weight.

  • Page 11: Continous Mode

    6. CONTINUOUS MODE 6.1 OVERVIEW In the Continuous Operating Mode, measurements are continuously transmitted by the instru- ment in a standard data format using printable ASCII characters at a user-selectable rate ranging from 50 or 60 Hz line frequency down to one measurement every 72 seconds. This data may be received by a remote display at a distant location, by a printer for data logging purposes, or by a host computer for data analysis or system control.

    7. COMMAND MODE 7.1 OVERVIEW In the Command Mode, the device does not send any data automatically, but responds to com- mands received from a host computer. These commands can be: • To transmit the latest or peak measurement • To reset the meter completely or just the peak value and/or latched alarms •...

  • Page 21 could each be displaying a different Item value. Also, the extracted value is put into Item 3 where it may be selected for Alarm comparisons and/or Analog Output. If a Coded Alarm character is included at the end of the sequence, it is ignored. The remote display reading can only be changed by Meter Reset, a *1C4 Remote display reset command, or another remote display H or L command.
