1.1 Operating Modes

The 120 supports the following modes of operation:

Normal (weighing) mode

Normal mode is the “production” mode of the indicator. The indicator displays gross or net weights as required, using the LED annunciators described in Section 1.3 on page 2 to indicate scale status and the type of weight value displayed. Once configuration i indicator, this is the only mode in which the 120 can operate. See Section 1.4.1 on page 3 for more information about normal mode operations.

Note

When editing numeric values, press to allow numeric mode change entry, then press or to change the digit selected. Press or to increment or decrement the value of the ﬂashing selected digit.

Press to save the value entered and return to the level above.

The EDP command set can be used to configure the 120 indicator using a personal computer, terminal, or remote keyboard. Like Revolution, EDP command configuration sends commands to the indicator EDP port; unlike Revolution, EDP commands can be sent using any external device capable of sending ASCII characters over a serial connection.

EDP commands duplicate the functions available usin

g the indicator front panel and provide some functions not otherwise available. EDP commands can be used to simulate pressing front panel keys, to configure the indicator, or to dump lists of parameter settings. See Section 5.0 on page 23 for more information about using the EDP command set.

3.1.3 Front Panel Configuration

The 120 indicator can be configured using a series of menus accessed through the indicator front panel when the indicator is in setup mode. Table 3-1 summarizes the functions of each of the main menus.

The following sections provide graphic representations of the 120 menu structures. In the actual menu structure, the settings you choose under each parameter are arranged horizontally. To save page space, menu choices are shown in vertical columns. The factory default setting appears at the top of each column.

Most menu diagrams are accompanied by a table that describes all parameters and parameter values with that menu. Default parameter values are shown in bold type.

Graduations. Specifies the number of full scale graduations. The value entered must be in the range 1–100 000 and should be consistent with legal requirements and environmental limits on system resolution.

To calculate GRADS, use the formula, GRADS = Capacity / Display Divisions. Display divisions for primary and secondary units are specified on the FORMAT menu.

Zero track band. Automatically zeroes the scale when within the range specified, as long as the input is within the configured zero range (ZRANGE parameter). Selections are ± display divisions. Maximum legal value varies depending on local regulations.

Zero range. Selects the range within which the scale can be zeroed. The 1.9% selection is ± 1.9% around the calibrated zero point, for a total range of 3.8%. Indicator must be at standstill to zero the scale. Use 1.9% for legal-for-trade applications.

Motion band. Sets the level, in display divisions, at which scale motion is detected. If motion is not detected for 1 second or more, the standstill symbol lights. Some operations, including print, tare, and zero, require the scale to be at standstill. Maximum legal value varies depending on local regulations.

If OFF is selected, ZTRKBN should also be set to OFF.

Overload. Determines the point at which the display blanks and an out-of-range error message is displayed. Maximum legal value varies depending on local regulations.

Sample rate. Selects measurement rate, in samples per second, of the analog-to-digital converter. Lower sample rate values provide greater signal noise immunity.

Digital filtering. Selects the digital filtering rate used to reduce the effects of mechanical vibration from the immediate area of the scale.

Choices indicate the number of A/D conversions that are averaged to obtain the displayed reading. A higher number gives a more accurate display by minimizing the effect of a few noisy readings, but slows down the settling rate of the indicator. See Section 7.6 on page 34 for more information on digital filtering.

Digital filter cutout sensitivity. Specifies the number of consecutive readings that must fall outside the filter threshold (DFTHRH parameter) before digital filtering is suspended. If NONE is selected, the filter is always enabled.
