SCALE ASSEMBLY

The Detecto 4500 Series Platform Mechanical Scale comes partially assembled. The following components require assembly: x Column x Draft Rod

Tools required: x Phillips head screwdriver x Wrench

1. Set the scale base on a table or other assembly area free from traffic and obstructions.

2. Remove the cable tie that secures the draft rod during transit (shown in Figure 1).

3. Insert the column onto the scale base (shown in Figure 2), ensuring that the DETECTO logo on the weigh beam faces the scale base.

4. Using a Phillips screwdriver, install the eight screws and washers to secure the column to the scale base as shown in Figure 3.

5. Lay the scale on a table. Remove and discard the shipping tie wrap wires on the underside of the scale base as shown in Figure 4.

6. Insert the wrench (included) into the small hole in front of the draft rod and pull the draft rod hook with the wrench to connect it to the long lever as shown in Figure 5. The draft rod is located inside the scale column. Once the column is attached to the scale base, the draft rod must be attached to the long lever.

7. Push the long lever forward and hook the draft rod’s hook onto the long lever pivot.

IMPORTANT! During shipping, a plug is installed to ensure that the shelf lever assembly stays aligned, however the linkage may still come out of alignment.

Remove the plug and then visually ensure that the shelf lever assembly linkage is centered and properly aligned. The linkage must be free floating in order for the scale to weigh properly. If the scale is slightly tipped to one side, the linkage can be seen by looking up underneath the weigh beam headpiece.

8. Place the scale gently back on the floor.

BALANCING THE SCALE

After assembly, the scale must be balanced prior to use.

1. Ensure the scale is sitting on a level surface, and slide both the small and large poise to zero (far-left position on the weigh beam).

2. Gently hold the beam pointer with your finger so it is centered within the trig loop area.

Release the beam pointer and let it rise freely up or down.

3. If the beam pointer doesn’t remain centered, turn the balance screw (shown in Figure 7) to the right or left using a flathead screwdriver until the beam pointer remains centered within the trig loop.

OPERATING THE SCALE

The following steps will guide you through the operation of your Detecto 4500 Series Platform

Mechanical Scale. Refer to Figure 8 below when performing the steps.

1. Move both poises to the Zero position. Be sure the Beam Pointer is in the center of the opening in the Trig Loop.

2. Slide the Large Poise to the approximate weight. For example, if the item weighs approximately 20 pounds, slide the Large Poise to 10 pounds.

3. Place the item on the scale; and then slide the Small Poise to 5 pounds.

4. Continue sliding the Small Poise until the Beam Pointer is centered in the Trig Loop opening.

5. Read the Small Poise at the pointer and add to the 10 pounds from the Large Poise. For example, if the pointer is at 8 pounds, the item weighs 18 pounds.

TROUBLESHOOTING

The Detecto 4500 Series Platform Mechanical Scale is factory-calibrated to within plus or minus 1/4 pound (0.1 kg) accuracy. For the most accurate readings, always use the scale on a hard, level surface and stand in the center of the scale platform with the weight evenly distributed. If an error occurs or seems excessive, check the following:

Problem

Zero balance out of adjustment

Possible Solution x The weighing beam must be balanced so the beam pointer comes to a rest in the center of the trig loop when both the small and large poise are set at zero (far-left position). Refer to Figure 7 and the BALANCING THE SCALE instructions.

Beam does not move freely

Platform rocks excessively

Beam does not move at all during weighing

Scale is out of calibration x Make sure the beam pointer is not touching the side of the trig loop, impeding its range of travel. x Visually ensure that the linkage is centered and properly aligned. Occasionally during shipping, the alignment will become skewed. The linkage must be free floating in order for the scale to weigh properly. If the scale is slightly tipped to one side, the linkage can be seen by looking up underneath the weigh beam headpiece. x Ensure the scale is setting on a level surface. When you push down on any corner of the platform, you should not feel any significant rocking. x Small and large poise are set higher than the person’s actual weight. Reset the both poises to a lower or zero weight. x Make sure the draft rod is properly connected and aligned as shown in Figure 5. x Recalibrate the scale by placing a known weight on the scale and turning the balance screw until the pointer remains centered within the trig loop.
