Introduction 1
1.0 Introduction
Congratulations on choosing a scale from the
BenchMark™series, the highest-quality single-point
benchtop scale available. The following types of
NTEP-approved BenchMark scales are available: Authorized distributors and their employees can
view or download this manual from the Rice Lake Weighing
Systems distributor site at: www.ricelake.com
• The light-capacity SL series featuring stainless steel construction in 10"x10" and 12"x12" platforms with
capacities from 5 lb to 100 lb.
• A mid-range model with a 12"x18" platform and a cover and frame that are constructed of stainless steel.
This model is available in capacities from 50 lb to 100 lb.
•The medium-capacity series is constructed with stainless steel covers, and mild steel—or optional
stainless steel—frame construction. This series is available in sizes from 12" x 12" up to 24" x 24" in
capacities from 30 lb to 1,000 lb. This manual covers each scale series.
One exciting feature of the BenchMark series is its ability to be converted into a checkweigher. By adding the
neck and head from a CW-80 CheckWeigher to your BenchMark scale, the features of a checkweigher are
available to you. Contact your Rice Lake Weighing Systems distributor for more information.
1.1 10"x10" and 12"x12" SL Models
All seven models of the 10" x 10" and 12"x12" SL series have stainless steel covers and frame systems. All
models use an RL1042 load cell. The 10, 20, 30, 50, and 100 lb models come standard with a potted RL1042 load
cell that offers extra protection against water infiltration but is not designed for washdown use. The 30, 50, and
100 lb models can also be supplied with an RL1140 stainless steel load cell. Extra load cell protection is also
available in optional stainless steel “clamshells” which enclose the load cell. See Section 7.0 for information
about clamshell installation. All load cells come with 10 feet of cable.
Figure 1-1. Overload Springs
The SL series scales use a sensitive 4-point, spring-plate suspension to minimize shock and overload damage
susceptible of light-capacity scales. The system uses a bolt and an overload protection spring at each of four
loading points beneath the top cover (see Figure 1-1). Each spring is set for a specific tension so that it will
compress to prevent overload damage. If a potentially damaging load is placed on a corner of the scale, the spring
at that corner compresses. When the spring compresses, the load is taken off the load cell. This eliminates the
possibility of overloading the load cell. Likewise, if a load more than 150% of total capacity is placed anywhere
on the deck, the springs will compress and remove the load from the load cell.
In addition to the overload protection spring, the SL models incorporate a load cell overload protection screw
beneath the load cell to help prevent overload damage.
To protect the load cell from being accidentally forced upward and damaged by improperly lifting the scale by
the spider, a lift up protection screw is incorporated into the design (see Figure 1-2).

2Benchmark Series Installation & Service Manual
1.2 12", 18", and 24" Models
Larger models in the series use mild steel frames and stainless steel deck covers for light washdown with a damp
sponge. All models are available with mild steel or optional stainless steel underbody frame construction. The
standard load cell is either an RL1042 or RL1260, depending on capacity. Options include a stainless steel
RL1140 load cell for 12" x 12" and 12" x 18" models and protective stainless steel clamshells for all models
using RL1042 or RL1260 load cells. All load cells come with 10 feet of cabling.
Figure 1-3. 12" x 12" With Overloads
These medium-capacity bench scales provide overload protection for the load cell by positive stops located
beneath each corner of the top frame (see Figure 1-3). These 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.
1.3 12" x 18" Stainless Steel
The 12" x 18" model has a stainless steel cover and underbody frame to meet USDA requirements and make it
ideal for washdown use. The 12" x 18: comes standard with an RL1042 load cell; a stainless steel load cell is
optional for both the 50 lb and 100 lb models. Extra load cell protection is available with the optional stainless
steel "clamshell" that encloses the load cell. See Section 7.0 for information about clamshell installation. All
locad cells come with 10 feet of cabling.

2.0 Installation
2.1 Leveling Scale
Remove the scale from the shipping container and place it in the desired location. Lift off the deck cover and
locate the bubble level. Adjust the four corner feet until the scale is level and all feet contact the support surface
so the scale does not rock. Lock the jam nuts on the feet when the final level is correct.
2.2 Connecting the Load Cell Cable
All models come with 10 feet of color-coded load cell cable. Do not cut this cable. The load cell is
temperature-compensated for an exact cable length of 10 feet.
See your indicator manual to determine the proper load cell cable input connectors. Use the following color
codes to wire the load cell cable.
For 6-wire operation: For 4-wire operation:
* Connect Sense and Excitation wires together if using 4-wire
system without sense leads.
2.3 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.

Calibration 5
3.0 Calibration
It is recommended that the scale be “exercised” by loading it to near capacity 2 or 3 times before calibration to be
certain that everything is seated. To calibrate your BenchMark:
1. With no load on scale, place the indicator in its calibration mode and perform a zero calibration.
2. Place test weights on platform equal to 70%–100% of scale’s capacity. If several weights are used, they
distribute them evenly around the platform.
3. Perform a span calibration.
4. Remove the test weights and check the zero reading. If necessary, repeat the calibration process.
See the indicator manual for the specific indicator calibration procedure.
4.0 Troubleshooting Guide
Use the following troubleshooting tips for the Benchmark scale if necessary.
Symptom Probable Cause Remedy
No display Power disconnected Connect power
Cable cut or disconnected Repair cable
Signal leads incorrectly wired at indicator Connect according to the manual
Display starts at zero Incorrect load cell cable connections Connect according to the manual
Faulty indicator Service indicator

6.0 Load Cell Replacement Table
The following table illustrates the load cell replacement numbers used with the Benchmark scales.
7.0 Installing Protective Clamshells
Stainless steel enclosures called clamshells are
available to provide extra protection for the load cell
of every BenchMark scale. All clamshells are
pre-drilled for load cell screws, overload screws, and
cables. Any existing load cell shims or spacers are
installed inside the clamshells.
The lower clamshell fits inside the upper clamshell
and is installed first. Position the clamshell so that no
part of it touches the load cell, then tighten the lower
load cell screws to the specifications given in the load
cell replacement section of this manual. When
installing the upper clam shell, position it so there is
clearance on all sides to prevent any binding problems
with the lower clam shell. Tighten the upper load cell
screws to the required torque.
When installation is complete, reset all overload
protection screws as described in Section 5.0, Load
Cell Replacement. Calibrate the scale according to the
procedure described in Section 3.0.
