1.2 Overview
The BenchMark MS is constructed with a mild steel frame with stainless steel top cover. The BenchMark SS and HE are
constructed with a stainless steel frame and top cover. The BenchMark MS and SS contain IP66 aluminum single point load
cells. The BenchMark HE contains an IP69K stainless steel single point load cell.
Overload Protection
The medium-to high-capacity bench scales provide overload protection with positive stops located beneath each corner of the
top frame. The overload stops are set at the factory for 100% of scale capacity.
Additional overload protection is provided by an overload screw beneath the load cell to help prevent shock damage.

2.0 Installation
This section provides an overview of how to install the BenchMark MS, SS and HE medium-to high-capacity bench scales.
2.1 Unpacking
Immediately after unpacking, visually inspect the scale to ensure that the unit is undamaged. The shipping carton should
contain the bench scale and this manual. If the bench scale was damaged in shipment, notify Rice Lake Weighing Systems and
the shipper immediately.
2.2 Leveling the Scale
1. Place the scale in the desired location that is reasonably level and free of unnecessary vibrations and air currents.
2. Lift off the scale top cover and locate the level bubble.
3. Adjust the four corner feet on the scale base until the level bubble and all feet contact the support surface so the scale
does not rock.
4. Lock the jam nuts on the feet when the final level is correct.
2.3 Connecting the Load Cell Cable
All models come with 10' of color-coded load cell cable.
Do not cut this cable. Cutting this cable voids the warranty.
See the indicator manual to determine the proper load cell cable input connectors. Use the following color codes to
wire the load cell cable to the indicator.

2.3.3 BenchMark HE
Connect Sense and Excitation wires together if using 4-wire system without sense leads.
2.4 Grounding the Scale Base
Bench scales can build up a static electricity charge during weighing operations. If powerful enough, this charge can travel
through the load cell cable to the indicator. To prevent this, all bench scales should be adequately grounded so that static
charges and transient electrical surges can drain directly to ground. Recommended practice is to connect the scale base to an
AC ground circuit using at least #12 wire. All BenchMark scales have either a grounding screw or a hole for such a grounding
screw located on the bottom of the lower frame for this purpose.
2.5 Calibration
It is recommended that the scale be exercised by loading it to near capacity two or three times before calibration to ensure
everything is seated. See the specific indicator manual for the proper calibration procedure.
To calibrate, see the following procedure:
1. With no load on scale, place the indicator in its calibration mode and perform a zero calibration.
2. Place certified calibration weights on platform equal to 70%–100% of scale’s capacity. If several weights are used,
distribute them evenly around the platform.
3. Perform a calibration.
4. Remove certified calibration weights and check the zero reading. If necessary, repeat the calibration process.
See the indicator manual for the specific indicator calibration procedure.

3.4 Load Cell Replacement
See the following procedure to replace load cells:
1. Unplug AC power from indicator and disconnect load cell cable from indicator.
2. Lift off the top cover.
3. Remove two load cell screws.
4. Lift off top spider.
5. Remove the spacer plate.
Figure 3-2. 12'' x 12'' Load Cell Mount
6. Loosen the four overload stop screws and turn each screw in one turn to provide ample clearance for the new load
cell. Turn scale over and back off overload protection screw one complete turn to provide clearance.
7. Unscrew and remove lower load cell screws. Depending on model of scale, there will be either two or four lower load
cell screws.
8. Remove bottom shim beneath load cell and set it aside.
9. Remove load cell and cable from scale.
10. Thread cable of replacement load cell through rubber grommet.
11. Position bottom shim directly beneath load cell and screw in lower load cell screws. Torque to 80 in-lbs for 12'' x 12''
and 12'' x 18'' scales, to 120 in-lb for 18'' x 18'', 18'' x 24'', and 24'' x 24'' scales.
12. Turn scale right side up. Position spacer plate on load cell, then place top spider into position.
13. Screw in four upper load cell screws. Torque to 80 in-lbs for 12'' x 12'' and 12'' x 18'' scales, to 120 in-lb for 18'' x 18'',
18'' x 24'', and 24'' x 24'' scales.
14. Connect load cell cable to indicator.
15. Recalibrate scale as described in Section 2.5 on page 4 of this manual.
16. Adjust overload protection screw on bottom of scale by loading scale to 125% capacity. Place this weight on top cover,
centered on platform. Use a hex wrench to screw in overload protection screw until it touches the load cell, then back
off 1/6 turn. Recheck calibration.
17. To reset corner overload stop screws, load top spider over one corner with approximately 30% of scale capacity.
Adjust screw under that corner to just touch top frame. Place a drop of a non-permanent, high-strength locking
compound such as LOCTITE® on the thread. Back screw off slightly so it is not touching.
