Chapter 1 - Overview
CHAPTER 1 - OVERVIEW
Introduction Congratulations on your purchase of a Hardy
Bench Scale. Behind your purchase is over 90
years of quality, reliability and technical innova
tion.
The Hardy Bench Scales are designed for table
top or floor applications requiring high accuracy
and reliability. The covers are all stainless steel
for durability. The bases have no bearings, spirit
levels, or moving parts that can be damaged or
wear out. The active element of the scale is a
precise and accurate strain gauge load sensor.
Description All Hardy Bench Scales come standard in
12”x12”, 18”x18”, and 24”x24” size s, an d ran ge
in capacity from 5lbs – 1,000lbs (2.27kg to 454
kg). Custom sizes and capacities are available
from Hardy upon request.
The basic Hardy Bench Scale consists of three
major components:
-
1. Stainless Steel Top Cover.
2. Lower Frame Assembly with a load sensor
3. Four Leveling feet.
The Stainless S teel Top Cover
Lower Frame Assembly
Scale Interface Directly attach the scale’s 10 foot (3 meter) cable
The top cover is a single piece constructed of
heavy gauge 304 Stainless Steel. The cover pro
vides a washdown weighing surface and offers
protection to the load sensor and electronics.
The lower frame comes equipped with four leveling feet, a load sensor, a shock load and corner
overload protection. Depending on the model,
the frame is made of stainless steel or painted
carbon steel.

Hardy Bench Scale Models
400 Series – HIBS400-xxxx
300 Series – HIBS300-xxxx
The HI BS400 Series is Hardy’s top of the line
industrial bench scale. With all stainless steel
construction and a hermetically sealed, IP68/
IP69K, FM Hazardous approved, stainless steel
Advantage® load cell, the HI BS400 is built for
the heaviest wash down applications and corro
sive environments. Hardy has built its C2 weightfree calibration technology into every scale,
delivering the lowest total cost of ownership on
the market. C2 calibration saves time during
commissioning and replacement, rem ov es per
sonnel from processing areas, and keeps your
process cleaner by eliminating the need for
potentially contaminated test weights.
The Hardy HI BS300 Series is a Hardy’s lowest
cost stainless steel industrial scale, built to han
dle light wash down and humid environments.
Each bench scale is equipped with an FM
approved IP67 aluminum load cell, and comes
with NTEP (pending) certifications standard. The
HI BS300 does not come with C2.

CHAPTER 3 - INSTALLATION
Precautions Do not store or operate the scale out of its spec-
ified temperature range. (See Temperature
Ranges in Chapter 2)
Do not store other equipment on the scale when
it is not in use or in storage.
Do not allow a build-up of debris on, around or
under the scale.
Do not set the scale in water or allow water to
settle around the scale. Provide Proper drainage.
Do not allow static or other electrical discharges
through the scale.
Do not try to repair the scale. Contact Hardy
Process Solutions T echnical Su pport Department
for any and all repairs.
Unpacking Hardy Bench scales are shipped fully assembled
and only require adjustment of the overload
stops and adjustment of the leveling feet. If there
is any damage to the shipping container or to the
scale, save all the packaging material and file a
report with the shipper.
Adjusting the Mechanical Overload Stops
There is a bolt in each corner of the frame that is
fully engaged for shipping protection. Each
should be adjusted to allow the load cell to
deflect to its maximum deflection distance, but
no further.

Leveling the Scale Step 1. The Hardy Bench Scales come with an
integrated leveling indicator at the front
of the base. (See Fig. 3-1). Remove
the top cover and locate the indicator
at the center of the front of the scale
base.

Step 2. To level the platform, turn the leveling
feet clockwise to lower the scale cor

Make sure the cable is not pinched and is clear
of the feet. The Bench Scale requires a recom
mended DC or AC excitation voltage of 5 volts
with a maximum of 15 volts. Wire the Scale cable
to an instrument or indicator following the color
code label found on the cable.

About Calibration of the Hardy Bench Scale
C2 Second Generation Calibration
NOTE: Hardy C2 calibration is only available in the
Test Weight Calibration (Hard Cal)
The Hardy Bench Scales come calibrated from
the factory . Make sure the scale is correctly wired
to the weighing instrument or indicator. Refer to
the weighing instrument or indicator manual for
calibration instructions.
C2 electronically calibrates a scale system without the need for test weights. If you are using a
Hardy Process Solutions Weight Controller,
Weight Processor , Indicator or W eigh Module, all
that’s required is to enter a reference point. Re fer
to the instrument or module manual for calibra
tion instructions using C2/
HI BS400 model as a standard feature.
This is the traditional means of calibration requiring certified class F test weights equal to a minimum of 80% of the rated scale capacity.
Three weights between 10% and 100% of the
scale capacity should be available to check the
mid-range. Several low capacity weights equiva
lent to one or two instrument divisions are necessary to check the system sensitivity.
-
-
NOTE: Traditional Calibration is required for the HI
BS200 and HI BS300 models because they do
not come with C2 load cells.
Material Substitution When certified test weights are not available you
can use an accurately weighed material to cali
brate the system. In this method, a material is
weighed on a secondary, calibrated scale and
delivered to the site of the scale to be calibrated.
The secondary calibrated scale should be of the
same accuracy or greater and have a capacity
approximately equal to the scale being cali
brated.

Chapter 5- Troubleshooting
CHAPTER 5- TROUBLESHOOTING
SCOPE All the information in Chapter 5 pertains to the
troubleshooting and resolution of operating prob
lems that may occur. All maintenance personnel
and users should be familiar with both Chapters
3 and 4 before attempting to troubleshoot prob
lems with the Scale.
Problem:

-
Scale Does Not Respond When Weight is Applied
Scale Indication is not linear
Scale Reads Backwards
Step 1. Make sure the scale is wired correctly
to the instrument or network and there
are no breaks in the wiring.
Step 2. Check to see if there is packing mate-
rial or debris wedged under or against
the scale.
Step 3. Make sure the corner mechanical
overload stops are not engaged with
the platform. Lower as necessary.
Step 1. Check the instrument for proper cali-
bration.
Step 2. Check to see if there is packing mate-
rial or debris wedged under or on the
side of the scale.
Step 3. Make sure the corner mechanical
overload stops are not engaged with
the platform. Lower as necessary.
Step 4. Make sure all electrical connections
are tight with no corrosion and that
there has not been an ingress of mois
ture to the system.
Step 1. Check for correct wiring to the instru-
ment. The +- signal or excitation wires
may be reversed.

Step 2. Make sure the corner mechanical
overload stops are not engaged with
the platform. Lower as necessary.
Step 3. Verify that the instrument or network is
operating properly.
Step 4. Make sure there are no high voltage
wires close to the scale.
Step 5. Check that the scale and instrument
are properly grounded.
Step 6. If high static electricity is present a
ground strap should be added from the
top cover to the chassis and to earth
ground.
