GRADS
10000
1–9999999
Specifies the number of full scale graduations if SPLIT=OFF. (For multi-range and
multi-interval scales (SPLIT
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 1–9999999 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.
SPLIT
OFF
2RNG
3RNG
2INTVL
3INTVL
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 3-6 on page 34 and parameter descriptions in Table 3-4 on page 35.

For standard scales (SPLIT=OFF), see Level 4 submenu descriptions in Table 3-3 on
page 31.
For multi-range and multi-interval scales, see Table 3-4 on page 35.
ZTRKBND
0
number
Automatically zeroes the scale when within the range specified, as long as the input is
within the ZRANGE and scale is at standstill. Specify the zero tracking band in ± display
divisions. Maximum legal value varies depending on local regulations.
Note
For scales using linear calibration, do not set the zero tracking band to a
value greater than that specified for the first linearization point.
ZRANGE
1.900000
number
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. Use the default value for legal-for-trade applications.
MOTBAND
1
number
Sets the level, in display divisions, at which scale motion is detected. If motion is not
detected for the SSTIME (default of 1 second) or more, the standstill symbol lights. Some
operations, including print, tare, and zero, require the scale to be at standstill. The value
entered must be in the range of 0-100. Maximum legal value varies depending on local
regulations.
If this parameter is set to 0, the standstill annunciator is set continuously on, and operations
including zero, print, and tare will be performed regardless of scale motion. If 0 is selected,
ZTRKBND must also be set to 0.
SSTIME
10
number
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. Values greater than 10 (1 second) are not
recommended.
OVRLOAD
FS+2%
FS+1D
FS+9D
FS
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.
WMTTHRH
1000
number
Specifies the minimum number of grads required for a weighment to be added to the
recorded number of weighments.
