UNPACKING AND ASSEMBLING THE FIELD TEST SCALE
Carefully remove the Field Test Scale from the carton.
Place the scale on a flat level surface and remove packaging material from the
scale.
Remove the weight hanger, weight set and platform from carton.
Place attachment weight hanger in loop and weights on weight rack as shown in
figure below.
Carefully assemble the platform to the top of the threaded post.
The Field Test Scale is now ready for use and should look like figure below.
WEIGHING
1. Set the scale on a reasonably level surface. The level condition is not critical;
however, it should not be obviously badly out of level.
2. The scale is in balance when the beam oscillates between the limiting stops.
Adjust the zero balance before beginning to use the scale so that the beam will
oscillate in that manner, that is with the poise set to the left side of the beam.
For adjustments to zero the scale, turn the balance compensation weights on
the left end of the beam (knurled nuts).
3. To weigh, place the object on the pan, slide the poise on the beam to a position
to cause the beam to oscillate between the stops. If the item being weighed
exceeds the beam capacity, add sufficient slotted attachment weights to cause
the end of the beam to move down. Then slide the poise back on the beam
until a balanced condition is achieved. The weight is the value of the total
accumulation of attachment weights plus the value read from the position of the
poise on the beam.
TRANSPORTING THE SCALE
The Field Test Scale is portable and can be moved from place to place without
damage. A handle has been provided in the back edge of the base. When
transporting the scale, pick it up by the handle, not by the scale beam or the
platform pan assembly. Be sure to remove the attachment weights and the
attachment weight hanger before picking up the scale.
CARE AND MAINTENANCE
With reasonable care, your Field Test Scale can be kept in good working order.
1. Avoid severe impacts to the platform or the beam.
2. Keep the scale clean. Foreign material should not be permitted to accumulate
in the pivot and bearing areas.
3. Never apply oil or any lubricant to the pivots or bearings.
