Parameter Choices Description
ADPFIL Sub-menu
AFSENS LIGHT
MEDIUM
HEAVY
Digital filter cutout sensitivity – the light setting responds quickly to small weight changes and
is less stable. The heavy setting responds slowly to small weight changes and is more stable.
Use the heavy setting in an unstable environment.
AFTHRH 000002 Digital filter cutout threshold – specifies the filter threshold, in weight value. When a weight
change exceeds the value set for threshold, digital filtering is suspended. A setting of zero
disables the filter. The decimal point in the entered value is assumed, so if the display division
is 1lb, a value of 1 is equal to 1lb. If the dd is 0.1lb, a value of 1 is equal to 0.1lb.

RFSTG3 2 , 4, 8, 16,
32, 64, 1
Rolling filter stages – the number of A/D samples that are averaged in each stage.
A higher number gives a more stable display by minimizing the effect of a few noisy readings,
but slows down the settling rate of the indicator. See Section 9.11 on page 68 for more
information on digital filtering.

Rolling filter cutout sensitivity – specifies the number of consecutive readings that must fall
outside the rolling filter threshold (RFTHRH parameter) before digital filtering is suspended. If
NONE is selected, the filter is always enabled.

Rolling filter cutout threshold – specifies the rolling filter threshold, in display divisions. When a
specified number of consecutive scale readings (RFSENS parameter) fall outside of this
threshold, digital filtering is suspended. If NONE is selected, the filter is always enabled.
