5.5.7 Automatic zero tracking
In case of change of the empty scale (hopper weight) e.g. due to loss (dead load reduction) or formation of slag
(dead load increase) by only a very low amount, automatic zero tracking ensures that the scale is reset to zero
automatically.
Automatic zero tracking is defined with the following parameters. With the scale in standstill condition and the
gross weight within the zero set range, automatic zero tracking is stepwisely done (step width) at defined
intervals.
5.5.8 Automatic zero correction switch-on/off
Switch-on: interval > 0 (
Zerotrk.ti > 0
)
Switch-off: interval = 0 (
Zerotrk.ti = 0
)
5.5.9 Zero tracking range:
Zerotrk.rn
Permissible range 0.00d to 500.00d.
5.5.10 Zero tracking stepwidth:
Zerotrk.st
Permissible range 0.00d to 10.00d
• For W&M applications, the correction must not be above 0.5 d/sek.
• The automatic zero tracking stepwidth must be smaller than the standstill range also for non W&M
applications.
5.5.11 Zero tracking interval:
Zerotrk.ti
Entry is in multiples of measuring time, permissible range 0 ( = off) to 100
• Switching off the automatic zero tracking is by setting Zerotrk.ti = 0.
5.5.12 Multirange scale
The multirange function is controlled by three parameters in the calibration. With
Multirange mode= on
the scale has three ranges with different resolution: the change-over limits
Multirange
limit 1
and
Multirange limit 2
represents the range border. If the gross weight has more d as the relevant
change-over limit, the next (wider) stepwidth is used (1->2->5->10->20->50).
If the gross weight is <= 0.25 d of the lowest range, the scale in standstill and untared condition, the scale will
be switched back to the lowest range.
During Calibration the multirange function is principally switched off.
5.5.13 Tare time-out:
Tare timot
Unless the tare command can be executed within time n (n = number of measuring times), e.g. because the
scale was not in standstill condition, the weighing point module generates a message (e.g. no standstill
noStAnd).
