GRADS 10000
1–9999999 Specifies the number of full scale graduations.
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 for primary and secondary units are specified under the FORMAT
submenu.

20D Automatically zeroes the scale when within the range specified, as long as the input is
within the ZRANGE and scale is at standstill. Selections are ± display divisions. Maximum
legal value varies depending on local regulations.
ZRANGE 1.9%
100% 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.

20D
OFF 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 OFF, the standstill annunciator does not light; operations normally
requiring standstill (zero, tare, print) are performed regardless of scale motion. If OFF is
selected, ZTRKBND must also be set to OFF.
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.

2 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 per update 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 10.9 on page 106 for more information about digital filtering.
