Figure 3-8. Scale Menu Structure
Graduations – specifies the number of full scale graduations if SPLIT=OFF. (For multi-range and
multi-interval scales (SPLIT is not OFF), the GRADS value is derived from the capacity and
display divisions specified for the range or interval.)
The value entered must be in the range 1–100000 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 are specified under the FORMAT submenu.
Multi-range/Interval – specifies whether the scale is full-range (OFF), multi-range (2RNG, 3RNG),
or multi-interval (2INTVL, 3INTVL). For multi-range and multi-interval scales, see the submenu
shown in Figure 3-9 on page 30 and parameter descriptions in Table 3-6.
See Figure 3-9.
Zero Track Band – automatically zeroes the scale when within the range specified, as long as the
input iswithin the ZRANGE and scale is at standstill. Specify the zero tracking band in ± display
divisions. Maximum legal value varies depending on local regulations.
Zero Range – selects the range within which the scale can be zeroed. The 1.900000 default
value is ±1.9% around the calibrated zero point, for a total range of 3.8%. Indicator must be at
standstill to zero the scale. Maximum legal value varies depending on local regulations.
Motion Band – sets the level, in display divisions, at which scale motion is detected. If motion is
notdetected 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 this parameter is set to 0 the standstill annunciator is always lit; operations normally requiring
standstill (zero, tare, print) are performed regardless of scale motion. If 0 isselected, ZTRKBND
must also be set to 0.
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.
Standstill Time – specifies the length of time the scale must be out of motion, in 0.1-second
intervals, before the scale is considered to be at standstill.
Display update rate. Specifies the display update rate, in the number of 100-millisecond intervals
between updates.
Sample rate. Selects measurement rate, in samples per second, of the analog-to-digital
converter. Lower sample rate values provide greater signal noise immunity.
Settings of 120Hz or above may be too fast to provide the desired stability insome static
weighing applications.
Digital filtering sensitivity
Digital filter cutout threshold, value is in grads.
Tare function – Enables or disables push-button and keyed tare.
BOTH – Both push-button and keyed tares are enabled
NOTARE – No tare allowed (gross mode only)
PBTARE – Push-button tares enabled
KEYED – Keyed tare enabled
