1.2 Safety / Proper Usage

Caution!

Note the force gauge’s capacity before use and ensure that the capaci ty is not exceeded.
Producing a force greater than 150% of the gauge’s capacity can damage the internal load cell. An

overload can occur whether the gauge is powered on or off.
Before use, each person who is to use the Series 4 force gauge should be fully trained in appropriate

operation and safety procedures.

Typical materials able to be tested include many manufactured items, such as springs, electronic
components, fasteners, caps, films, mechanical assemblies, and many others. Items that should not be used
with the gauge include potentially flammable substances or products, items that can shatter in an unsafe
manner, and any other components that can present an exceedingly hazardous situation when acted upon
by a force.

CF 182 1 32-1117 1010

The following safety checks and procedures should be performed before and during o peration:

1. Never operate the gauge if there is any visible damage to the AC adapter or the gauge itself.

2. Ensure that the gauge is kept away from water or any other electrically conductive liquids at all
times.

3. The gauge should be serviced by a trained technician only. AC power must be disconnected and
the gauge must be powered off before the housing is opened.

4. Always consider the characteristics of the sample being tested before initiating a test. A risk
assessment should be carried out beforehand to ensure that all safety measures have been
addressed and implemented.

5. Wear eye and face protection when testing, especially when testing brittle samples that have the
potential to shatter under force. Be aware of the dangers posed by potential energy that can
accumulate in the sample during testing. Extra bodily protection should be worn if a destructive
failure of a test sample is possible.

6. In certain applications, such as the testing of brittle samples that can shatter, or other applications
that could lead to a hazardous situation, it is strongly recommended that a machine guarding system
be employed to protect the operator and others in the vicinity from shards or debris.

7. When the gauge is not in use, ensure that the power is turned off.

2 POWER

The gauge is powered either by an 8.4V NiMH rechargeable battery or by an AC adapter. Since these
batteries are subject to self discharge, it may be necessary to recharge the unit after a prolonged period of
storage. Plug the accompanying charger into the AC outlet and insert the charger plug into the receptacle on
the gauge (refer to the illustration below). The battery will fully charge in approximately 8 hours.

Caution!

Do not use chargers or batteries other than specified or instrument damage may occur.

If the AC adapter is plugged in, a corresponding icon appears in the lower left corner of the display, as
follows:

If the AC adapter is not plugged in, battery power drainage is denoted in a three step process:

The gauge can be configured to automatically power off following a period of inactivity. Refer to the Other
Settings section for details.

If battery replacement is necessary, the battery may be accessed by separating the two halves of the gauge.
Refer to the Mechanical Setup section for details.

CF 182 2 32-1117 1010

1. When battery life is greater than 30%, no indicator is present.

2. When battery life drops to approximately 30%, an indicator appears as follows:

3. When battery life drops to approximately 10%, the indicator will appear as follows:

4. When battery life drops to approximately 2%, the indicator from step 2 will be flashing. Several
minutes after (timing depends on usage and whether the backlight is turned on or off), a message
will appear, “BATTERY VOLTAGE TOO LOW. POWERING OFF”. A 4-tone audio indicator will
sound and the gauge will power off.

43 MECHANICAL SETUP

3.1 Loading shaft orientation

In order to accommodate a variety of testing requirements, the orientation of the loading shaft may be set up
in either of the two positions shown below. In order to change the loading shaft orientation, loosen the two
captive screws on the back side of the housing, separate the two housing halves, rotate one half 180
degrees, and reassemble. Contact between the two halves is made by the spring pins and contact pads on
the printed circuit boards.

3.2 Mounting to a plate

Although the gauge may be used by hand, proper mounting is important if attached to a fixture or test stand.
The round steel insert with a hole in the back of the housing is provided to withstand the load during a test. A
mating dowel pin should be used (see illustration below). Mounting plates on Cooper test stands inclu de a
dowel pin and clearance holes for the four threaded holes located near the corn ers of the housing. These
holes are designed to accommodate screws in order to hold the gauge in place (Cooper test stands include a
set of thumb screws for gauge mounting). The screws must not be used for load bearing purposes. Failure
to use a dowel pin properly can result in a hazardous situation.

3.3 Mounting attachments to the gauge

The force gauge’s threaded loading shaft is designed to accommodate common grips and attachments with
female mounting holes. To mount a grip, gently thread it onto the shaft. Other mounting adapters are also
available to prevent rotation. Ensure that the grip or fixture is positioned to ensure axial load with respect to
the loading shaft of the force gauge. When using a grip, ensure that it secures the sample in such a way that
it is prevented from slipping out during a test, preventing a potential safety risk to the5operator and others in
the vicinity. If using a grip or fixture from a supplier other than Cooper, ensure that it is constructed of suitably
rugged materials and components.

Do not use jam nuts or tools to tighten grips or attachments onto the shaft. Finger-tighten only. Antirotation
mounting adapters are available.

Caution!

In any operating mode, if the capacity of the instrument has been exceeded by more than 110%, the
display will show “OVER” to indicate an overload. A continuous audible tone will be sounded until
the MENU key has been pressed or the load has been reduced to a safe level.

Three operating modes are possible with Series 4 gauges. To cycle between the modes, press MODE while
in the home screen.

5.1 Real time (RT)

The primary reading corresponds to the live measured reading.

5.2 Peak Compression (PC)

The primary reading corresponds to the peak compression reading observed. If the actual force decreases
from the peak value, the peak will still be retained in the primary reading area of the display.
Pressing ZERO will reset the value.

5.3 Peak Tension (PT)

Same as Peak Compression, but for tension readings.

6 DIGITAL FILTERS

Digital filters are provided to help smooth out the readings in situations where there is mechanical
interference in the work area or test sample. These filters utilize the moving average technique in which
consecutive readings are pushed through a buffer and the displayed reading i s the average of the buffer
contents. By varying the length of the buffer, a variable smoothing effect can be achieved. The selection of 1
will disable the filter since the average of a single value is the value itself.

To access digital filter settings, select Filters from the menu. The display will appear as follows:

8

Two filters are available:

Current Reading – Applies to the peak capture rate of the instrument.
Displayed Reading – Applies to the primary reading on the display.

Available settings: 1,2,4,8,16,32,64,128,256,512,1024. It is recommended to keep the current reading filter at
its lowest value for best performance, and the displayed reading filter at its highest value for best stability.

7 SET POINTS

7.1 General Information

Set points are useful for tolerance checking (pass/fail),
triggering an external device such as a motorized test stand,

CF 182 6 32-1117 1010

or alarm indication in process control applications. Two limits, high and low, are specified and stored in the
non-volatile memory of the instrument and the primary reading is compared to these limits. The results of the
comparisons are indicated through the three outputs provided on the 15-pin connector, thus providing
“under”, “in range”, and “over” signaling. These outputs can be connected to indicators, buzzers, or relays as
required for the application.

Limited Warranty on Products

Any Cooper Instruments product which, under normal operating conditions, proves defective in material or in
workmanship within one year of the date of shipment by Cooper will be repaired or replaced free of charge
provided that a return material authorization is obtained from Cooper and the defective product is sent,

properly installed, maintained, and operated within the limits of rated and normal usage. Replacement or
repaired product will be shipped F.O.B. from our plant. The terms of this warranty do not extend to any
product or part thereof which, under normal usage, has an inherently shorter useful life than one year. The
replacement warranty detailed here is the buyer’s exclusive remedy, and will satisfy all obligations of Cooper

consequential loss or damage which might result from a failure of any and all other warranties, express or
implied, including implied warranty of merchantability or fitness for particular purpose. Any unauthorized
disassembly or attempt to repair voids this warranty.

evaluation charge. Please return the original calibration data with the unit.

Repair Warranty

All repairs of Cooper products are warranted for a period of 90 days from date of shipment. This warranty
applies only to those items that were found defective and repaired; it does not apply to products in which no

to be returned to the exact original specifications or dimensions.
