Parameter Choices 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.
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 will be 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.
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
30HZ
60HZ
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.
DIGFL1
DIGFL2
DIGFL3 2

1 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 7.7 on page 45 for more information on digital filtering.
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. If
NONE is selected, the filter is always enabled.
