    When the indicator starts “m2000 “ will scroll across the screen followed by the version number of the software. The indicator performs a full diagnostic of its internal circuits and will display any error messages if there is an internal problem with the indicator.

  • Page 12: Special Keypad Functions

    The most common functions are discussed below. 3.2.1 Selecting scale channels The M2000 has three independent scale channels. Press the channel number followed by the PRINT SELECT key as shown below. To select channel 1 press 1 followed by the print select key.

    5.1.1 Special Keypad function keys during calibration 5.1.1.1 Selecting a calibration parameter. The M2000 uses parameter numbers to access calibration functions. Each cal function has a unique number used to access that parameter. In calibration mode the print select key now becomes the calibration function select key.

    5.1.1.4 Toggle between weight and AD counts. A unique feature of the M2000 is the ability to toggle between weight and the AD converters internal counts. This can be an excellent diagnostic tool for the experience scale technician. Pressing the ON/OFF key will show the internal AD counts.

  • Page 19: Calibrating With Weights

    5.2 Calibrating with Weights A complete calibration of the scale would include all the steps described in this section in order: set the parameters, balance the scale, deadload the indicator, and set the span. 5.2.1 Set the Scale Parameters Set or verify all the parameter settings for your application. Refer to section 4 for details on the settings for common applications.

The update rate has nothing to do with the actual AD converter update rate or filtering. The parameter may have a value between 0-9. A value of 0 will introduce no delay in the display update, while a maximum value of 9 will introduce a display update rate of a 3-second delay.

    This parameter disables the faststep system altogether. The values for parameter 42 and 43 are ignored and the system runs in weight averaging mode only. The response time for the indicator is a function of parameter 41. Some control batching applications may require that faststep be turned off. 8.11 PRINTING Parameters 84 Add new ticket This parameter appends a new ticket to the end of the ticket buffer.
