Mechanical Balance Beam Scales (400 series)
The scale needs to be calibrated.
There is a hexagon adjustment screw underneath the base of the scale holding the lever extension to the scale’s lever system. (Please see the photos in your instruction manual.) Please do not loosen the hex screw too much because it will fall out and once out cannot be reinserted properly. Once loosened you can slide ... The scale needs to be calibrated.
My scale is inconsistent and giving different readings each time a weight is registered.
First make sure the scale is balanced at zero before weighing. If the scale is balanced and the beam pointer is floating freely and scale is still reading inconsistent, platform may be pressing against the base causing the base to possibly be out of alignment. There should be an even space between the platform and ... My scale is inconsistent and giving different readings each time a weight is registered.
My beam is not moving freely.
Remove the end caps (the rectangular box next to the large poise with the medical emblem on it). There is one screw in the front and one in the back. Once caps have been removed sternly jiggle the beam assembly to loosen the scale mechanics. With caps still off balance the beam with the adjustment ... My beam is not moving freely.
My scale will not balance at zero.
Place both the large and small poise on zero (make sure both poises are in the zero notches all the way to the left shoulder of the beam). To balance the beam at zero, turn the adjustment screw to the left of the beam counter clockwise to raise the beam pointer or clockwise to lower ... My scale will not balance at zero.
