Parameter Choices Description
Level 2 submenus
GRADS 10000
number Specifies the number of full scale graduations.
The value entered must be in the range 1–9 999 999 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.
ZTRKBND OFF
0.5D
1D
3D 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.
MOTBAND 1D

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.
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.
SMPRAT 15HZ
30HZ
60HZ
120HZ
7.5HZ Sample rate. Selects measurement rate, in samples per second, of the analog-to-digital
converter. Lower sample rate values provide greater signal noise immunity. If instability
occurs, use lower sample rate to reduce signal noise.
DIGFLT1
DIGFLT2 4

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.
RATTRAP OFF
ON
Enables RATTLETRAP ® digital filtering. RATTLETRAP is most effective at filtering repeating
vibrations caused by mechanical noise from nearby machines but may increase settling
times over standard digital filter selections.
DFSENS 8OUT
16OUT
32OUT
64OUT
128OUT
2OUT
4OUT Digital filter cutout sensitivity. Specifies the number of consecutive readings that must fall
outside the filter threshold (DFTHRH parameter) before digital filtering is suspended.
