  • Page 53: Calibration

    Calibration Calibration The 820i can be calibrated using the front panel, serial commands, or Revolution®. Each method consists of the following steps: • Zero calibration • Entering the test weight value • Span calibration • Optional five-point linearization • 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: Serial Command Calibration

    820i Programmable HMI Indicator/Controller Calibrate Performs calibration for the selected point Temp Zero Temporarily zeroes the displayed weight of a non-empty scale. After span calibration, the difference between the temp zero and the previously calibrated zero value is used as an offset.

    Diagnostic Boot Procedure If a user program causes an error in the start-up handler, press and hold the setup switch while cycling power to the 820i to place the indicator in setup mode. Use Revolution monitor mode to send the PCLR command erase clear the user program.

  • Page 99: Using The Xe Serial Command

    10.1.4 Using the XE Serial Command The XE serial command can be used to remotely query the 820i for the error conditions shown on the front panel. The XE command returns a decimal number representing any existing error conditions. For multi-scale applications, the value returned by the XE command represents all error conditions, if any, present on all configured scales.

    820i Programmable HMI Indicator/Controller 10.2 Regulatory Mode Functions The function of the front panel keys depends on the value specified for the REGULAT parameter on the TARE ZERO FEATURE menu. Table 10-4 describes the function of these keys for the NTEP, CANADA, OIML, and NONE regulatory modes.

  • Page 101: Serial Scale Interface

    Serial ports 3, 4 and any expansion ports can be configured for serial scale input. The serial scale function allows other scale indicators to send gross, net, or tare weight data to the 820i. Once a serial port has been configured to accept scale data, the data format can be customized to match the data stream sent by that indicator.

    820i Programmable HMI Indicator/Controller 10.5 Custom Stream Formatting Each port can be independently configured to stream a default frame format or can be customized to stream a user-defined format. Custom formatting is very similar to the standard print formatting described in Section 6.0.

Use the following procedure to determine vibration effects on the scale and optimize the digital filtering configuration. 1. In setup mode, set the digital filter parameters (DIGFLT1–DIGFLT3) to 1. Set DFTHRH to NONE. Return indicator to normal mode.

    Appendix 10.8 Conversion Factors for Secondary Units The 820i has the capability to mathematically convert a weight into many different types of units and instantly display those results with a press of the key. UNITS Secondary and tertiary units can be specified on the FORMAT menu using the SECNDR and TERTIA parameters, or by using serial commands.
