The system will multiply the sensed load by any number selected by the user to suit
the actual reeving arrangement for a given set up. The overload threshold levels also
receive the correct values which are the measured threshold levels multiplied by the
number of falls.
The set points are also multiplied by the multi number automatically.
Best Practice
When weighing with multiple rope falls, the friction created by the pulleys will have an effect
on the displayed load. This friction will always be in opposition to the direction of the load's
movement. When lifting, the displayed value will be that of the load + the force of the
friction. When lowering, the opposite will be true and the displayed value will be less than
the actual load. We recommend that measurements are taken either only while lifting, or only
while lowering the load, with the latter being preferred. This will minimize the error in the
displayed load.
4.9 Dampened Reading aka Averaging
To switch on the dampening mode, press ZERO + TARE simultaneously. The display
will show AVR.ON.
To switch off the dampening mode, press both keys again. The display will show
AVR.OF.
When calibrating the system, avoid using dampening, i.e. turn off the dampening
mode.
The dampening option is effective mainly in cases where instability in the lifted load is
cyclical, such as in a load that swings in the manner of a pendulum. In this case the
dampening option can find the real weight in a relatively short amount of time, before
the load stops swinging. In fact, if the load is in constant motion, this will be the only
practical way to find the load's true weight.
In cases where the load changes randomly the dampening option is very limited in its
performance, especially when high rates of change are involved.
