There are two fundamentally different ways of weighing with the Weighlog -
Dynamic weighing and Static weighing. You can select the weighing method
for each of the five channels on the instrument.
4.1 Dynamic weighing
Dynamic weighing means that the weight is measured without interrupting the
lift. The load is lifted straight through the reference position. Dynamic
weighing can give consistent results without significantly slowing down the
loading cycle, but it does rely on a certain degree of care on the part of the
operator (section 2.2).
1.
Lift the load
through
the reference position. The alarm will sound one beep.
The display will then show the net weight in the bucket.
The weight will remain displayed until you lower the bucket below the
reference position.
2.
With the bucket in the raised position,
p
ress the Remote Enter Button to add
the weight to the sub-total for the selected channel (and to the TOTAL
channel).
4.2
Static weighing
Static weighing requires the load to be lifted or lowered to the reference
position and held there. The display will show a "live reading" which will
fluctuate as the machine settles. You can tip off excess material as required,
therefore static weighing is ideal for the last bucket load if you are aiming to
reach a target load.
1.
Lift the load up to the weighing position. The alarm will sound one beep and
the "live" weight will be displayed. If you go too high the display will show 4
bars (fig. 6).
2.
It is a peculiarity of hydraulic systems that the pressure (and therefore the
load reading) will diminish for some time after the load is stopped at the
reference position, therefore you should allow a short while for the weight
reading to settle down.
3.
Press the Remote Enter Button to add the weight to the sub-total for the
selected channel (and to the TOTAL channel).
