SCALE OPERATION INSTRUCTIONS
The following steps will guide you through operation of the portable platform beam type scale.
Figure No. 2
Portable Platform Beam Type Scale Operation Components
1.
With no load on the scale platform, move the Sliding
Poise to zero, and then unlock the Beam Lock. The
Beam Tip should be centered vertically in the Trig
Loop. If the tip is not centered, turn the Zero Adjust
Screw until it is. See Figure No. 3.
2.
Lock the Beam with the Beam Lock, and then place
the item to be weighed on the scale platform.
3.
Add Counterpoise Weights to an amount slightly less
than the estimated weight of the item, and then
release the Beam Lock.
4.
The Beam should rise to the top of the Trig Loop. If it
does not, reduce amount of Counterpoise Weights.
5.
Next, move the Sliding Poise along the Beam until
the Beam balances with the tip centered in the Trig Loop.
6.
When the Beam balances, the weight of the item is the value indicated by the Sliding Poise,
plus the face value of the Counterpoise Weights used.
For example, if there are two pounds of Counterpoise Weights (equivalent to 200
pounds) and the Sliding Poise on the Beam indicates 62.5 pounds, then the item on the
scale platform weighs 262.5 pounds.
For a metric example, if there are two 1 kg Counterpoise Weights (equivalent to 200 kg)
and the Sliding Poise on the Beam indicates 19.6 kg, then the item on the scale platform
weighs 219.6 kg.
7.
After the weight has been determined, lock the beam and then remove the item from the
scale platform.
NOTE:
The Sliding Poise may be locked at the reading by tightening the Poise Screw if the
desired weight is needed repeatedly, such as when filling propane tanks.
