The Type allows for different measuring configurations If a weigh hopper is on load cells then the weight increases as material is batched Up to hopper but if for instance a cement silo is on load cells then the weight decreases as cement is batched Down no hopper The value Up Direct is for when there is no hopper and material is direct into the truck bowl typical of admixtures and water measured by flowmeter End loader plants generally have a remote display visible to the loader driver The Ext Display value is the port to which the external display is connected Except for an end loader weigh hopper the value is generally None Multiplier converts a physical measurement to a true measurement For scales the value can be left as zero which is treated as a multiplier of 1 i e there is no difference between the weight displayed on the scale and the actual scale weight If however an admixture flowmeter gives one pulse for every 10 ml then the multiplier needs to be set to 10 to convert pulses to milli litres of admixture If water is measured by a flow meter that gives 50 pulses per litre then the multiplier would be 0 02 Enabled is a yes no value tick box to indicate the counter is available for use If for example at a dual aggregate weigh bin plant one hopper was damaged it can be taken off line simply by unticking the check box then re ticking after repair This is a lot more convenient than deleteing then re entering the wh
