Chapter 1 - Overview
CHAPTER 1 - OVERVIEW
Introduction Congratulations on your purchase of a Hardy Instru-
ments Any-Weigh™ Bench Scales. Behind your purchase is over eighty years of quality, reliability and
technical innovation.
The Hardy Any-Weigh™ Bench Scales are designed
for table top or floor applications requiring high accu
racy and reliability. The covers are all stainless steel
for durability. The bases have no bearings, spirit lev
els, or moving parts that can be da maged or wear out .
The active element of the scale are precision strain
gauge load sensors.
NOTE: Any-Weigh™ is a trademark of Hardy Instruments
Incorporated.
Description The basic Any-Weigh Bench Scale consists of three
major components:
1. Stainless Steel Top Cover.
2. Lower Frame Assembly with Four Load Cells
3. Four Leveling feet.

The Stainless Steel Top Cover
Lower Frame Assembly
Universal Scale Interface
NOTE: WAVERSAVER® and C2® are registered trademarks
The top cover is a single piece constructed of series
300 Stainless Steel. The cover provides a weighing
surface and offers protection to the load cells and
electronics.
The lower frame comes equipped with four leveling
feet, four load cells, a shock load and co rner overload
protection. The lower frame is made of coated mild
steel.
Directly attach the scale’s 15 foot cable to any weighing instrument or controller. If interfacing with a
Hardy Controller, you can take full advantage of
WAVERSAVER
of Hardy Instruments Incorporated.

DeviceNet™ Scale With DeviceNet™ you can use the scale to provide a
weight output to any point on a DeviceNet™ Net
-
work. This version also incorporates both the
WAVERSAVER
®
and C2® technologies. The
DeviceNet™ Scale comes with a fifteen inch mini
mum length pig-tail connector.
NOTE: DeviceNet™ is a trademark of the Open DeviceNet
Vendor Association.
Analog Scale The Analog Scale provides a 4-20mA output directly
proportional to the weight read ing. This version of fers
a low-cost, solution for bringing analog weight read
ings directly into a control system. The Analog Scale
requires minimal additional wiring or hardware and
comes with a 15 foot shielded 2 wire cable.

Preinstallation Precautions
Do not store or operate the scale out of its specified
temperature range. (See T emp erature Ranges in Chap
ter 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 let moisture get on or into any of the electrical
interconnections.
Do not allow static or other electrical discharges
through the scale.
Do not try to remove the top plate.
Do not try to repair the scale. Contact Hardy Instru-
ments Technical Support Department for any and all
repairs.

Unpacking The Any-Weigh Bench scales are shipped fully
assembled and only require 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.
Leveling the Scale Step 1. Place the spirit level across each corner
and adjust if necessary to level the corners.

WARNING USE CAUTION WHEN WIRING. MAKE SURE
Make sure the cable is not pinched and is clear of the
feet. The Bench Scale requires a recommended 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
upper frame or as follows:
