Revolution supports both uploading and downloading of indicator configuration data.

  • Page 53: Calibration

    4.0 Calibration ® The 480 can be calibrated using the front panel or the Revolution configuration utility. Each method consists of the following steps: • Zero calibration • Entering the test weight value • Span calibration • Optional rezero calibration for test weights using hooks or chains. The following sections describe the calibration procedure for each of the calibration methods.

  • Page 54: Edp Command Calibration

    4.2 EDP Command Calibration To calibrate the indicator using EDP commands, the indicator COM 1 port must be connected to a terminal or computer. See Section 6.0 on page 51 for more information about using EDP commands. Once the indicator is connected to the sending device, use the following steps: 1.

    Print Formatting The 480 provides multiple print formats, GFMT, NFMT, ACCFMT and SPFMT, that determine the format of the printed output when the key is pressed. If a tare has been entered or acquired, NFMT is used; otherwise, Print GFMT is used. Each print format can be customized to include up to 300 characters of information, such as company name and address, on printed tickets.

    Setpoints The 480 indicator provides eight configurable setpoints for control of both indicator and external equipment functions. Setpoints can be configured to perform actions or functions based on specified parameter conditions. Parameters associated with various setpoint kinds can, for example, be configured to perform functions (print, tare, accumulate), to change the state of a digital output controlling indicator or external equipment functions, or to make conditional decisions.

Scale data from the local indicator is also displayed at the remote unit, and keypad input from the remote allows transactions to be initiated from either the local or remote unit. To configure for local/remote operation, set STREAM to local or remote.

  • Page 73: Internal Battery Option

    Example: If the standby parameter set to 1 second, the weight threshold to 100, and the display division threshold is set to 10d, once in sleep mode, the indicator will wake up every second for about half a second to check to see if a key is being pressed, the weight threshold is over 100 (WGTHRH), or the weight has change more than 10d (DDTHRH) since the last time it checked.

  • Page 76: Rolling Averaging Filter

    9.11.3 Rolling Averaging Filter The rolling averaging filter uses mathematical averaging with three stages. These configurable stages control the effect of a single A/D reading on the displayed weight. When an A/D reading is encountered that is outside a predetermined band, the rolling averaging filter is overridden and the display jumps directly to the new value. Filter Stages (RFSTG1-3) The filter stages can each be set to a value of 1 to 64.
