HIPS SERIES PLATFORM SCALES
1-1
Introduction Congratulations on your purchase of a Hardy Instru-
ments HIPS Series platform scale. The Hardy Plat-
form 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, bubble levels, or moving
parts that can be damaged or wear out. The active ele-
ment of the scale is a precision strain gauge load sen-
sor.
Each platform is certified for use in a C2®Second
Generation Calibration System.
Description The basic HIPS platform scale consists of four major
components:
1. Stainless Steel Platform Cover.
2. Upper Frame Assembly
3. Single Point Load Cell
4. Lower Frame Assembly
The Stainless
Steel Platform
Cover
The platform cover is a single piece constructed of
series 300 Stainless Steel. The cover provides a
weighing surface and offers protection to the load
cell. Access to the upper frame, load cell and lower
frame is gained by lifting up on the cover.
Upper Frame
Assembly The upper frame is bolted directly to the load cell and serves as support for the platform cover. In the HI
1212PS/S and the Hi 1318PS/S the upper frame is
made of cast aluminum. The HI 1842PS and HI
2424PS upper frame is all stainless steel. They all
have rubber load pads and a shock load adjustment.
Single Point Load
Cell The HIPS Series Platform Scales have potted alumi-
num load cells with a unique humidity resistant pro-
tective which assures long term stability even under
harsh environment and extreme temperatures. All
HIPSS series scales have potted stainless steel load
cells. Each cell has a six conductor cable, ten (10) feet

HIPS SERIES PLATFORM SCALES

long with C2®on its end. The output of each cell is
2mV/V with 5 to 15 volts DC excitation.
Lower Frame
Assembly The lower frame assembly is also bolted directly to the load cell and serves as support and protection. It
comes equipped with four leveling feet, a shock load
set screw and corner overload adjustments. The cor-
ner overload adjustments have been factory set to bot-
tom out at approximately 75% of the scale capacity.
DO NOT change this adjustment. As in the upper
frame assembly the HI 1212PS/S and the HI 1318PS/
S lower frame is made of cast aluminum. The HI
1824PS and HI 2424PS lower frame is all stainless
steel.
Preassembly
Precautions Do not store or operate the scale out of its specified
temperature range.
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 adjust the shock or over load stops.
Do not try to remove the load cell or adjust the allen
set screws above or below the load cell.
Unpacking and
Assembly The HIPS Series 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.

Make sure each corner of the upper frame assembly
has a rubber boot or strip and that there is a rubber
strip in the center for the HI 1212 and Hi 1318 scales.
For the HI 1824 and HI 2424, make sure there are rub-
ber strips in each corner, down the center and at the
center of each 24 inch length of the upper frame.
Leveling the Scale To level the scale, loosen the foot lock nut on the
lower frame assembly and turn the foot clockwise to
lower the scale corner, or counter clockwise to raise
it. Tighten the lock nut when no wobble of the scale is
detected.
Electrical Connections Make sure the cable is not pinched and is clear of the
feet, cover, and overload stops. The platform requires
a recommended DC or AC excitation voltage of 5
volts with a maximum of 15 volts. Wire the platform
load cell cable to an instrument or indicator following
the color code label found on the upper frame or as
follows:
+ Excitation Green
+ Sense Blue
+ Signal Red
+ C2 Cal Gray
- Signal White
- Sense Brown
- Excitation Black
- C2 Cal Violet
WARNING USE CAUTION WHEN WIRING. MAKE SURE
TO DISCONNECT ALL POWER TO THE
SCALE. FAILURE TO REMOVE POWER CAN
RESULT IN SCALE OR INSTRUMENT DAM-
AGE, DEGRADATION OF PERFORMANCE OR
PERSONAL INJURY
Calibration To calibrate the platform, make sure the platform is
wired correctly to the weighing instrument/indicator.
Refer to the weighing instrument/indicator manual for
calibration instructions.

C2 Second
Generation
Calibration
C2 electronically calibrates a scale system without the
need for test weights. If you are using a Hardy Instru-
ments HI 2151/20WC, HI 2151/30WC, HI 2160RC
controller or HI 1746-WS, Hardy HI 1771-WS weigh
module, all that’s required is to enter a reference
point. Refer to the instrument or module manual for
instructions.
Test Weight
Calibration (Hard
Cal)
This is the traditional means of calibration requiring
certified class F test weights equal to a minimum of
80% of the rated scale capacity. Additionally three
weights between 10% and 100% of the scale capacity
should be available to check the mid-range. Several
low capacity weights equivalent to one or two instru-
ment divisions are necessary to check the system sen-
sitivity.
Material
Substitution When certified test weights are not available you can use an accurately weighed material to calibrate 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 calibrated.

Troubleshooting
Scale does not
respond when
weight is applied
Step 1. Make sure the scale is wired correctly to
the instrument and there are no breaks in
the wiring.
Step 2. Lift off the lid and see if there is packing
material or debris wedged under the scale.
Step 3. Check to see that the corner stops are not
touching the top frame. On the 1824 or
2424 insure the shock bolt is not touching
the lower frame.
Step 4. Verify that the Instrument is operating cor-
rectly.
Scale indication is
not linear Step 1. Check the instrument for proper calibra-
tion.
Step 2. Lift off the lid and see if there is packing
material or debris wedged under the scale.

Step 3. Check that the corner stops are not touch-
ing the top frame. On the 1824 or 2424
insure the shock bolt is not touching the
lower frame.
Step 4. Make sure all electrical connections are
tight with no corrosion and that there has
not been an ingress of moisture to the sys-
tem.
Scale reads
backwards Check for correct wiring to the instrument. The +- signal or excitation wires may be reversed.
Scale reading
drifts or is erratic Step 1. Make sure all electrical connections are tight with no corrosion and that there has
not been an ingress of moisture to the sys-
tem.
Step 2. Verify that the instrument is operating
properly.
Step 3. Make sure there are no high voltage wires
close to the scale’s load sensor.
Step 4. Check that the scale and instrument are
properly grounded.
Step 5. If high static electricity is present a ground
strap should be added from the platform
cover to the lower frame assembly and to
earth ground.
