Description
Level 2 submenus
GRADS
10000
number
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.
ZTRKBN
OFF
0.5D
1D
3D
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.
ZRANGE
1.9%
100%
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.
MOTBAN

50D
OFF
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.
OVRLOA
FS+2%
FS+1D
FS+9D
FS
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.
SMPRAT
15HZ
7.5HZ
3.75HZ
30HZ
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.
