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 31 and parameter descriptions in Table 3-4 on page 32.
FORMAT PRIMAR
SECNDR
TERTIA
ROC For standard scales (SPLIT=OFF), see Level 4 submenu descriptions in Table 3-3 on
page 28.
For multi-range and multi-interval scales, see Table 3-4 on page 32.
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 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 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 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.
