5.5.2 Filter: Analog Filter
Select between filter = on or no filter = off.
The anlog filter (low-pass) has got a 2nd-order Butterworth characteristic with a cutoff frequency of 2Hz. The
filter is located before the ADC and should be set to on.
Digital Filter
Select between no or bessel (Bessel), aperiodic, butterw. (Butterworth) or tscheby (Tschebyscheff) filter. With
digital filter enter the cutoff frequency (Fcut 0.1 ... 5.00 Hz). The measuring time is fixed to 50 ms if the digital
filter is not off.
The digital filter (low-pass, 4-th order) is located behind the ADC, each 50 ms a new value is calculated.
For coarse / fine / flow control (e.g. Batch-X5, IBC-X5, Flow-X5) the weight values are taken before the digital
filter and therefore the digital filter has no influence on the control.
Weight values to be displayed / printed (e.g. amount batched, weight on a platform / weighbridge) are
generated after the digital filter.
• After changing of the filter parameters, the maximum accuracy should be reestablished by re-calibration.
5.5.3 Analog test mode:
Testmode
Determination, whether the test measurement displays the deviation related to
FullScale
(absolute) or to
0
(relative) is made.
Calibration (with/ without weights) is completed with a test measurement and the result is scaled so that
FullScale is displayed.
This value is displayed when pressing the key [ATest].
5.5.4 Measuring time:
Meastime
Measuring time in ms, enter 50 or 100 ... 2000 (multiples of 100), if digital filter is not set to off, the measuring
time is fixed to 50 ms.
5.5.5 Standstill detection
The standstill detection requires the two following parameters to determine the mechanical standstill of the
scale. During a defined period of time (standstill time), the weight value of the scale must be within defined
limits (the standstill range). In this case, the scale is in standstill condition.
Standstill range:
Standst.rn
Permissible range 0.00d to 10.00d.
Standstill time:
Standst.ti
Entry 'Number of measuring times', permissible range 1 … 8.
5.5.6 Zero set range:
Zeroset.rn
Definition of a +/- range around the calibration zero, within which
• the displayed gross weight can be set to zero by pressing the zero setting key (or by a corresponding external
command), or
• automatic zero tracking is active
Permissible range: 0.00d to 500.00d
