Calibration Steps
Adjust the analog interface indicator to the platform.
•Install all the corners to within one (1) division of each other at 25% of
rated capacity.
•Follow the appropriate indicator service manual to ensure a proper calibration.
The Junction Box Assembly (P/N 67171) has four (4) extended range, multi-
turn potentiometers, one for each load cell.
STEPS
1. Center the four Junction Box Potentiometers by turning the adjustment screw
counter-clock-wise position until a clicking sound is heard, then turning each of
them back clock-wise ten (10) turns.
─Total number of turns is twenty.
2. Identify the platform corner numbers.
3. Place a concentrated weight (25% of platform capacity)
on corner #1, then move it to #2, #3 and #4, noting the
displayed reading on each corner.
4. Identify the lowest reading, and then place the
concentrated weight on this corner.

Section3:ScaleInstallation
03/08 15 50612 Rev. 9
If corners do require adjustment, complete the following steps:
1. Place the concentrated weight on the corner displaying the lowest weight.
2. Turn the adjustment on the potentiometer clockwise (CW) to the displayed weight
so it reads the same as the highest reading.
3. Repeat this procedure while rechecking all corners until they are equal.
Important Note: When moving the weight(s) from corner to corner, DO NOT
zero the scale. The purpose is to adjust the corners to be the same, and not to
perform a correct calibration.
4. Perform a zero reference check with an unloaded platform,
5. Repeat the corner test to ensure all readings are the same before proceeding.
If ‘cornering' the platform is difficult, follow these steps.
1. Note which corner has the highest reading.
2. Turn all potentiometers to the full counter-clock-wise position until a
clicking sound is heard.
3. Place the weight on the lowest reading corner.
4. Turn the corresponding potentiometer clock-wise to read the same as the
corner with the highest reading.
5. Repeat each corner to match the one with the highest reading.
If corners do not require adjustment, complete the following steps:
1. Remove all weights.
2. Zero the indicator.
3. Perform a final calibration with test weights.
4. Follow the appropriate indicator service manual to ensure a proper calibration.

Section4:InstallingAccessories
Installing Bolt-Down Plates
Bolt down plates are used to keep the scale from sliding or moving when loads are
applied. The plates are bolted using anchors at each of the scales feet.
STEPS
1. Place the platform into the correct position.
2. Place the bolt-down plate under the foot. The plate edge extends out from under
the scale.
3. Drill two (2) 7/16” attachment holes using a hammer drill.
4. Insert anchors with the nut and washer already on them.
5. Tap the anchor into the hole, then tighten the nuts securely.
6. Repeat this process for each plate.
Note: If ramps are not installed and bolt-down plates are needed, then a full set of
four bolt-down plates are required.

Section4:InstallingAccessories
03/08 17 50612 Rev. 9
Installing Ramps
Each mild steel ramp accessory comes with two integral bolt-down plates and four
anchors.
STEPS
1. Place the ramp in position, then lift and set the platform feet into the bolt-down
plate holes.
2. Drill the
two (2) 7/16” holes using a hammer drill. Insert the anchors with the
nut and washer already on.
3. Tap the anchor into the hole, then tighten the nuts securely.
IMPORTANT TIPS
•If two ramps are installed, then no other bolt-down plates are needed.
•If only one ramp is installed, then a set of two bolt-down plates are necessary.
•Only two ramps (total) may be installed on opposite sides of a scale platform.
Installing Bumper Guards
Bumper Guards help protect the platform from direct hits from forklift traffic. The
guards are slightly higher than the scale and help deflect the forks.
STEPS
1. Place the bumper guard into a position so it protects the platform from non-scale
traffic.
─Place the bumper guard so it does not touch or interfere with the platform’s
movement.
2. Drill the 7/16” fastening holes using a hammer drill.
3. Insert the anchors with the nut and washer already on it.
4. Tap the anchor into the hole.
5. Tighten the nuts securely.

Section4:InstallingAccessories
03/08 18 50612 Rev. 9
Installing Pit Frames
The pit frame accessory is a one-piece welded unit.
─There are three (3) different type frames with six (6) sizes for each type.
─Two (2) are for the standard duty scale and one (1) is for the heavy capacity.
─The Pit Frame is designed for in-floor, or 'flush', applications.
─Standard duty frames are available in mild steel for all six floor scale sizes
For normal installations, a hole is cut in the concrete, the pit-frame accessory is
installed in the hole, then concrete is poured around and under the frame.
─The concrete work and frame setting is usually done by a contractor, with a
scale technician completing the project by setting and installing the scale.
─Once cured, the scale platform is set into the frame and installation can be
completed. No additional welding required.
STEPS
1. Place the pit frame in the approximate position it will occupy on
the floor.
2. Mark out the position of the hole to be made.
─The hole MUST be a minimum of twelve inches (12") wider on all
sides than the pit frame.
─The hole will have to be deep enough to accommodate the pit coping, plus the
thickness of the pit floor.
─Use the drawing in Appendix IV for measurements.
─Should pit drainage be required, slope the pit floor to an installed drain while
maintaining a level area at each corner.
3. Cut the hole in the concrete floor.
4. Clean up any debris in the way of further installation steps.
5. Set the frame in the hole supported at about the correct height.
6. Set two 2x4 's on edge (longer than the width of the hole) across the opening.

Section4:InstallingAccessories
03/08 19 50612 Rev. 9
Installing Pit Frames, Continued
7. Use soft wire and make two (2) loops by twisting wire around each 2x4 and
the frame.
8. With the frame supported by the wire and 2x4's, use a level to set the frame flush
with the surrounding floor, level, and at the correct height by twisting or untwisting
the wire.
NOTE: Use the drawing in Appendix IV for measurements, concrete
specifications and amounts.
9. Set into place and secure the conduit for the scale cable into the frame opening.
10.Pour the concrete around and under the frame.
11.Level and smooth it with a hand trowel, as needed.
12.If a drain is required, form the pit to place a slope in the pit floor to the drain.
─See Appendix IV.
─Allow cement to cure to a minimum of 2000 psi before cutting the wire.
13.Pull the cable through the conduit before placing the scale platform in the frame.
14.Level the platform before installing the instrumentation.
