Safety Precautions
! Place the scale on a flat and rigid surface
! Place the scale far from strong RF interference
! Level the scale using its adjustable feet
! Do not subject the platter to sudden impacts
! Do not spill the water or any other liquid on the scale
! Do not use any solvents to clean the scale
! Do not leave the scale in direct sunlight
Operating the Scale
Make sure the platter is sitting properly on top of the platform and that
there is nothing on top of the platter. Also, make sure that the scale is
plugged into the proper outlet. Place the power switch into the ON
position. The display will run through a self test and then go to zero.
The scale will always remain in the last mode that it was left in. The
display may appear as follows (it will read 0.0 if it is a 300 lb scale:)
Changing Modes
You can toggle through each of the 4 modes by pressing the MODE
key. If you start with pound mode (lb) then the MODE key will toggle
as follows:

Simple Weighing
1. Make sure that the scale is at ZERO and STABLE
2. Place a load on the platter
3. After the STABLE indicator turns on you may read the weight
4. Remove the load
Entering Tares
1. Make sure that the scale is at ZERO and STABLE
2. Place the container to be tared on the platter
3. After the STABLE indicator turns on press the TARE key
4. The display should be at zero and the NET, STABLE, and ZERO
lamps should all be on
Removing Tares
1. Make sure that the scale is at ZERO, STABLE, and NET
2. Remove the tared container from the platter
3. The display should be at a negative weight and the NET,
STABLE, and ZERO lamps should all be on
4. Press the TARE key
5. The display should now show zeros and be at ZERO and
STABLE
Simple Weighing Using Tares
1. Make sure that the scale is at ZERO and STABLE
2. Follow directions for entering a tare
3. Place a load on the platter
4. After the STABLE indicator turns on you may read the weight
5. Remove the load
6. You may continue to use the same tare by returning to step 3 in
this procedure, OR continue to step 7
7. Follow steps for Removing Tares
Parts Counting (This feature is NOT legal for trade.)
1. Press the MODE key until you reach Counting mode
2. Make sure that the scale is at ZERO, STABLE and PCS
3. Press the SET key
4. The display will read SEt 10
5. Place sample of 10 pieces on the platter and press the SET key
6. If the sample is not within the Minimum Piece Weight and
Minimum Sample Weight for the scale’s specific capacity, then the
scale will loop back to step 5 but this time asking for a sample of
20 pcs; if it fails again then 50 pcs; and finally 100 pcs.
(continued)

6
If the display stays at SEt 100 after you press SET more than
once, then the parts are too light
7. If the sample met the proper criterion, then you will see a count on
the display. See the chart below to determine the Minimum Piece
and Sample Weights
8. Remove the sample from the platter
9. If necessary, follow directions for entering a tare
10. Place a sample of quantity to be counted
11. Once the STABLE light is on you may read the pcs
12. Remove sample from the platter and repeat steps 10 thru 12 as
many times as necessary or proceed to step 13
13. If necessary, follow directions for removing a tare
