2 UNPACKING AND SETUP Each scale is individually packed in a carton specially desiipted to protect the scale and all its vital working parts. Upon unpacking the scale, care should be taken not to grasp it by the beam, but rather lift it by the base beneath the center post. Save the rubber washer used in packing and insert between parallel loop and base when scale is not in use. A reasonably flat and level surface should be selected on which to use the scale. On such a surface a very near balance should be attained when all of the poise are set to their respective zero marks. In the event that the scale does not balance exactly at zero when set up on its working surface, there are two knurled balance adjustment nuts provided in the beam to make the necessary balance correction. These nuts are locked against each other to prevent any movement in shipping or in use. When adjustments are made, unlock the nuts by turning them apart about a quarter turn; they can then be easily moved. When the correct balance has been restored, be sure to lock the balance nuts against each other so that there will be no chance for their movement and hence a change in the zero balance. It is also advisable to check the zero balance periodically since foreign material may accumulate on the scoop or beams and cause a slight change in the balance position. Whenever the scale is moved, the zero balance must be rechecked, since it will be affected by an appreciable change in the inclination of the working surface on which the scale rests. WEIGHING Please see other side.

3 WEIGHING Before proceeding with weighing make sure the scale is set up as described above. The determination of a weight on the 4 in 1 Scale is a very simple and rapid operation. The material to be weighed is placed in the scoop with both Doises at the zero marks. Next, manipulate the poise until a balance position is again obtained. The weight of the specimen can then be read directly from the beams through the indicator panels. You will note that the lower beam is notched at 50 gram to 500 gram intervals and the lower poise is equipped with a unique device enabling it to be used as either a straight sliding poise, or as a poise with a notch that will fall into definite locations. Various type weighings should be made as follows: 1. LBS/Bushel on 1 pint sample or kg/hi on 0.5 litre sample. Use poise in slide position, read lower indicator panel. To insure accurate results, fill bucket with No. 151 Filling Hopper. 2. Percentage Readings-The scale is equipped to read dockage or moisture percentage directly on a 500 gram sample. The large poise, set ir' "Notch" position, is set at 450 gram and the small poise is set at 50 gram. A 500 gram sample is then weighed out. After weight loss, the sample is reweighed by moving the large poise to the left to tl->~ tirst notch position which causes the beam to rise and then moving it back to the right one notch causing the beam to go back down: the small poise is then moved to the left until the beam balances. The percentage can then be read to the nearest.1 % by combining the readings of the two poises. If percentage readings to only the nearest 1% are desired, the large poise can be used alone, in "Slide" position, keeping the small poise at initial 50 gram position. 3. Weight in Grams-(Lower Poise in "Notch" Position) Read values in upper indicator panel. Set lower poise to nearest 50 gram notch. Add intermediate values with upper poise. 4. Weight in Ounces-Lower beam only. Poise in "Slide" position, read value in lower indicator panel. (Except Model 14M).
