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” sizes, and range
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.
TheStainlessSteel
Top Cover 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.
Lower Frame
Assembly The lower frame comes equipped with four level-
ing 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.
Scale Interface Directly attach the scale’s 10 foot (3 meter) cable
to any weighing instrument or controller. If inter-
facing with a Hardy Controller, you can take full
advantage of WAVERSAVER®and C2®Elec-

tronic Calibration (C2 is only available with HI
BS400 series).
NOTE: WAVERSAVER®and C2®are registered trade-
marks of Hardy Process Solutions.
Hardy Bench Scale
Models
400 Series –
HIBS400-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 weight-
free calibration technology into every scale,
delivering the lowest total cost of ownership on
the market. C2 calibration saves time during
commissioning and replacement, removes per-
sonnel from processing areas, and keeps your
process cleaner by eliminating the need for
potentially contaminated test weights.
300 Series –
HIBS300-xxxx 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.
200 Series –
HIBS200-xxxx The HI BS200 Series is Hardy’s lowest cost industrial scale, featuring a painted carbon steel
base and IP67 aluminum load cell made for use
in dry and dusty environments. Each aluminum
load cell is FM approved, and the HI BS200
comes with NTEP (pending) certifications stan-
dard. The HI BS200 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
ProcessSolutionsTechnicalSupportDepartment
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.
