Introduction Introduction This manual provides assembly and operating instructions for the RL1200 portable beam scale, which is available in both avoirdupois and metric. Please read all instructions carefully before assembling the scale. This manual covers the installation and setup of two versions of the RL1200: •...
There are certain precautions that should be taken to prevent personal injury to the user and damage to the scale. Care should be exercised to assure proper assembly and operation of the RL1200. The RL1200 should be assembled only by a trained scale technician.
Table 2-1. RL1200 Parts (Continued) Repacking If the RL1200 must be returned for modification or repair, it must be properly packed with sufficient packing materials. Whenever possible, use original carton when shipping the scale back. IMPORTANT: Damage caused by improper packaging is not covered by the warranty.
Assemble Wheels onto Frame Use the following steps to assemble wheels onto the RL1200 frame. 1. It is preferable to set the scale base on a box or other item to keep the scale base up off the floor. Tip the scale base on its side.
RL1200 Portable Beam Scale 2.3.2 Attach Pillar to Scale Base Use the following steps to attach the pillar to the scale base. 1. Screw the pillar rods into the scale base frame approximately three turns. Ensure ample threads are available to place the beam weight rack and beam cap assembly on the pillar.

Figure 2-9. Attach Hook to Nose Iron Assembly 4. Temporarily hang the steelyard rod on the cutout in the pillar as shown. Figure 2-10. Steelyard Hook on Pillar Cutout If assembling the Mechanical to Electronic version of the RL1200, please proceed to IMPORTANT: Section 4.0 on for further assembly instructions.

RL1200 Portable Beam Scale 6. Hang the counterpoise assembly from the loop assembly at the tip of the beam. Figure 2-17. Hanging Counterpoise Assembly 7. Place the scale on a firm, level surface. 8. Set poise(s) at zero and lock. Release the beam lock. Adjust the back balance assembly to bring the beam to a horizontal position with the tip centered in the trig loop.
RL1200 Portable Beam Scale Operation Use the following steps to safely and correctly operate the RL1200 platform scale. 1. With no load on the scale platform, position the sliding poise at zero. Unlock the trig loop. The beam should be centered vertically in the trig loop.
• Pre-drilled mounting bracket • All necessary conversion hardware The conversion kit requires no special tooling or equipment. Assembly requires only ordinary hand tools. Prior assembly of the RL1200 through Step 4, Figure 2-10 on page 9 still applies. Unpacking The Conversion Kit...
Table 4-1. Conversion Kits Parts List Indicator and Load Cell Installation Use the following steps to attach the indicator and load cell to the RL1200. 1. Take the indicator base plate and lay it on its side. 2. Note the orientation of the load cell. Put the 3.5 inch bolt through the long bolt washer and through the top of the indicator base plate.

RL1200 Portable Beam Scale 9. Set indicator on base plate and secure with four bolts and lock washers. Figure 4-6. Secure Indicator to Base Plate 10. Wrap excess cable around cable hooks on handle. Figure 4-7. Store Excess Load Cell Cable 11.
RL1200 Portable Beam Scale Appendix Check frequently for correct balance with no load on the platform, the poise(s) set at zero, and no counterpoise weights applied. • Keep the beam locked until the load has been applied to the platform.
