3.8 SETTING UP POGO LR PLUS OR EZ
AMETEK produces a range of Lloyd Instruments machines that can be mounted on specially designed frames that can be used for testing a wide range of bulky items such as cardboard cartons,
crates and furniture.
These “Pogo” machines have a linear bearing
fitted in the fixed lower crosshead through which
a rod runs, connecting the load cell and the compression platens mounted below the machine
within the frame.
Holes
No specific information about setting up a LR
Plus Pogo or EZ can be issued with the machine
on it’s own because the size and specification of
the mounting frame are decided by the customers specific needs.
The mounting frame should be positioned first
and the instructions for set-up and wiring supplied with the mounting frame followed closely.
The LR Plus or EZ Pogo will have been supplied
to you without the frame mounting plates fitted. The fitting of these plates needs to be carried
out prior to the machine being lifted onto the
Crusher Frame.
AMETEK recommend that the fitting of these
mounting plates is carried out by a Lloyd
Instruments appointed commissioning engineer
to suit the requirements and needs of the
customer.
Full fitting and wiring instructions are supplied
with the Crusher Frame. Fitting and wiring of the
Emergency Stop Buttons and Console are designed to meet each customer’s specific needs. The positioning of controls is the responsibility of
the final user who should ensure, as part of the
Risk Assessment, that sufficient stop buttons are
provided.
Because the mounting plates protrude from the
bottom of the LR Plus and EZ machines, no attempt should be made to stand the machine on
its own. It will only be stable when it is fitted and
secured to the mounting frame.
Suitable lifting equipment should be employed.
12
LR_Plus and EZ Series User Manual
Example Installation of LR Plus Pogo mounted
on a Carton Crusher Frame.
The Pogo Rod should be fitted last, once the LR Plus or EZ machine is secured to the top of the
frame. Insert the rod through the bearing on the lower (fixed) crosshead of the LR Plus or EZ
machine and connect to the Bottom Platen. Connect to the loadcell last.
Ones the machine is installed, wired and ready for its intended use, the final user must conduct the
final Risk Assessment on the machine, including all such safety measures (shield, guard etc.), to
satisfy the requirements of the Machinery Directive and EHSR (Essential Health and Safety
Requirements).
3.9 FITTING AND MOVING THE CONSOLE (OPTIONAL)
The console is fitted to the right side of the machine. The height and the angle of the console may be

4.0LOADCELLS
4.1
CARE OF LOAD CELLS
ALL machine operators should be aware that Lloyd Instruments load cells are precision force
measuring instruments, which should be treated with the utmost care to avoid accidental damage.
Low force cells are easily damaged if abused or used without sufficient care:
1.
Do not submit load cells to physical shock of any kind. DO NOT DROP!
2.
When a load cell is removed from a machine immediately put it in a safe and dry place.
3.
To install a load cell on all machines up to and including the LS100 Plus: Select the correct
size load cell adaptor. Place the adaptor through the hole in the moving crosshead with the
thread down. Carefully offer up the load cell and screw the load cell adaptor into the load cell,
taking care to ensure that the locating dowel on the load cell sits in one of the holes on the
under side of the moving crosshead and the connecting cable is on the same side as the
connecting socket. Tighten the load cell adaptor in the load cell thread with the C spanner
provided. Insert the load cell plug in the socket on the under side of the moving crosshead and
finger tighten the two retaining screws. Fit the eye end to the load cell and tighten with the C
spanner supplied.
4.
When installing the upper grip (particularly heavy ones) on the load cell eye end, avoid bumping
the eye end. If the grip is a close fit, DO NOT FORCE IT, establish the reason and rectify.
Immediately set, or re-set, the bottom limit stop so the grips will not meet when the crosshead is
lowered. See section 8.5 LIMIT STOPS.
5.
In both tension and compression tests, centre the specimen in line with the axis of the load cell
and the bottom fixed anchor pin to avoid side thrust.
6.
In compression tests, care must be taken to avoid bringing the platens together or against solid
specimens at high speed. Cells thus damaged cannot be repaired. Ensure that the lower
crosshead limit is set correctly. See section 8.5 LIMIT STOPS.
7.
In compression tests, if special lower fixtures are used, ensure that they are fixed in position so
they cannot be accidentally moved to block the normal downward movement of the upper
fixture, e.g. where a tongue on the upper fixture must fit into a slot in the lower fixture.
See section 8.4 LOWER ANCHOR PIN ADJUSTMENT.
8.
Avoid overloading beyond the cell’s rated capacity. Prior to testing ensure, if possible, that the
maximum force anticipated will not exceed the capacity of the cell installed. If maximum
capacity is approached during a test, run the machine at slow speed in local mode, and reverse
the crosshead if capacity is exceeded.
9.
Lloyd Instruments load cells are built to exceed the standards as set out by ASTM, BS, DIN etc.
All cells on the LR5K, 10K, 30K, 50K Plus, EZ20, EZ50 and LS100 Plus machines are userchangeable. Various capacities are available from 5N up to the capacity of the frame. While
cells may be used below 10% of capacity it is recommended that, when such lower forces
are anticipated, a lower force cell be installed such that the test force will fall in the upper 90% of its
range. This will give the best signal to noise performance of the load measuring system.
NOTE: All LLOYD INSTRUMENTS machines incorporate overload protection, which will stop
the machine if capacity is exceeded in either tension or compression. However, at higher
speeds, momentum may carry the crosshead far enough after shut-off to damage the cell. In
low force cells this distance is very short. Cells thus damaged cannot be repaired.

The keypad has 25 keys arranged into 4 groups.
The first group contains 8 keys in the bottom right hand corner of the keypad
First Group of Keys
The First Group of Keys
GO
The GO button is used to start a test from the machine console and is operable from the “Pre-Test”
display.
STOP
The STOP key is used to stop a test that is being performed from the machine console,e.g., if the
machine does not stop automatically or the user requires to abort the test. The STOP key is not operable when the machine is performing a test under the control of an external computer. This is not an
Emergency Stop Button. The Emergency Stop Button (Mushroom) is located on the left of machine
base and can be used to stop the machine in an emergency situation.
CAUTION: The Stop key is not to be used as the Emergency Stop.
JOG UP and DOWN
These two keys allow the crosshead to be moved slowly into position when loading and removing
samples. They are available when a test is not being performed and only operate whilst pressed.
The crosshead will run at a user pre-set jog speed (a set-up option).
FAST JOG UP and DOWN
These two keys allow the crosshead to be moved at maximum speed and therefore it is essential to
ensure there are no obstructions. These keys should only be used for moving large distances and
not for final adjustment when the grips are close together. They are available when a test is not being
performed and only operate whilst pressed.
ZERO Pressing this key sets the load and extension values to zero. This is normally carried out at the start
of a test but can be used at any time when not performing a test. If Auto Zero was selected in the
set-up routine the system will automatically zero when GO is pressed.
RETURN
Pressing this key returns the crosshead to the position where the zero button was last pressed. The
crosshead will move at maximum speed. The return button is available when a test is not being
performed.

6.0 PERFORMING A TEST
6.1 TEST MODES
The Lloyd Instruments machines can be used to perform tests in 2 modes. Firstly as a “stand alone”
machine or under the control of a computer running NEXYGENPlus™ or NEXYGEN™ software.
If the machine is to be used with a computer and NEXYGENPlus™ or NEXYGEN™ software, then
the NEXYGENPlus™ or NEXYGEN™ Software User Manual should be read in conjunction with this
manual. The machine should be connected to the computer with the RS232 lead supplied. When
the machine is on and ready, the computer connected with the lead supplied and NEXYGENPlus™ or
NEXYGEN™ running, connection between the machine and computer is automatic.
If the Lloyd Instruments machine is being used in “stand alone” mode, proceed as follows. The
following information will also be needed for “setting up” the machine with grips, samples etc.
6.2 TEST PARAMETERS
SAMPLE PREPARATION
The Jog Keys are used to prepare for a test. The accessories being used will be dependent on the
type of test being conducted.
LOAD CELLS
The correct load cell should be fitted in the machine for the application being undertaken. Great care
should be taken with these as they are precision measurement devices and can be damaged if used
incorrectly. Please read Section 8.0 carefully before proceeding further.
GRIPS/ADAPTORS
It is important that grips are fitted along the central straining axis of the machine and that no side
loads are applied to the load cells as this will affect the accuracy of the load readings. The grips
should be connected to the load cell and the bottom anchor pin using only the pins provided. Care
should be taken not to exceed the load rating of the grips. It is important to ensure that the grips
used are suitable for the material under test. Any slippage of the material in the grips will affect both
load and extension readings.
EXTENSOMETERS
It is important to understand that the extension that the crosshead moves does not give a true reading of the strain in the samples. If we consider a dumbbell sample for instance, the strain will be
different at different positions along the sample and no account is being taken of the take up of slack
or bedding in of the grips. For accurate strain readings we would strongly recommend the use of a
Lloyd Instruments extensometer which is suited for the material under test.
ENVIRONMENTALCHAMBERS If an environmental chamber is used with your materials testing machine there should be sufficient room behind the machine to slide the oven back away from
the working area. It is important to ensure that the cut-off valve for the liquid coolant should be in
an accessible place. Grips and other accessories are fitted to the machine with the environmental
chamber in its fully forward position. The access holes at the top and bottom of the chamber should
be positioned as centrally as possible along the straining axis of the machine.
CAUTION: Extreme care should be taken when dismantling grips or extracting samples
after a test in the Environmental Chamber. This should be done only with suitable protective clothing, i.e. gloves, to prevent risk of burns.

7.0 SETTING UP A NEW TEST
7.1 PRE-DEFINED TEST SETUPS
The LRX Plus is supplied with three pre-defined test setups and one for new test setups, these are:
LIMIT_TEST
A test which is carried out to a limit. The limits are defined in mm or inches,
% elongation (after setting gauge length), Newtons, Kg force, lbs force, Mega
Pascal’s Mpa (have entered the sample dimensions), Kg force per mm² and lb
force per inch².
CYCLE_TEST
A cycle is from home to a limit (as set out above) and back to home. If when
the test starts the crosshead is not at the home position, it will move to the
home position first before going to the limit position. The machine can be set
to perform up to 10000 cycles per test. If necessary this 10000 limit can be
raised by your agent or dealer.
BREAK_TEST
A Break Test will either, stop at a limit as described above or when a break is
detected. There are 2 types of break detector. A % break detector which
detects when the load has dropped to 50% of the maximum peak load
detected and sharp break detector. The sharp break detector operates when
there has been a sharp change in load or direction between one load reading
and the next.
NEW_TEST
Is a user defined test rather than one of the default settings which are detailed
on the next page.

8.0 OPERATIONAL PRECAUTIONS
8.1SAFETY
Lloyd Instruments materials testing machines are inherently safe if used properly. Operators must be
made aware that:
1. High physical forces are involved.
2. Samples under test may shatter.
3. Electrical power supplies are involved.
4. The following must ALWAYS be brought to the attention of any operator before they are allowed
to use the machine. Hands, fingers and other parts of the body must at all times be kept well
away from the moving crosshead. Operators should be particularly careful when moving the
crosshead to insert test samples, to ensure that no part of the hand could be accidentally
compressed as the crosshead and grips are jogged into position.
5. NEVER drive the machine from a computer when anyone else is working on or near the
straining frame.
6. If there is any danger that liquids may be spilt during tests, operators must use a drip tray
(which is available from AMETEK) to guard against the possibility of any spillage
entering the machine and giving rise to electrical or other hazards.
7. Take extra care when operating in compression mode where specimens may burst, shatter or
fly out from between the platens. Operators should STAND CLEAR during testing. Splinter
shields are available.
8. All operators must receive adequate training in basic operation before being allowed to use the
machine. Additional copies of this manual are available from AMETEK.
9. Operators must ensure that the Emergency Stop Button is never obstructed.
10. Operators must ensure that other personnel working in or near the area are made aware that
testing is taking place and that they should not approach the machine while it is in use.
11. Operators must ensure that the machine is regularly serviced and calibrated by
Lloyd Instruments or one of their accredited service dealers.
12. To maintain EMC compatibility, the machine should only be used as prescribed in this manual.
Connecting cables, plugs and sockets should be inspected regularly. Cables damaged or worn
in any way should not be used. Accessories and accessory connecting leads, if suspect, should
be replaced only with a Lloyd Instruments approved replacement. Failure to observe this may
cause your machine to infringe the EMC legal requirements.
13. Never attempt any form of machine maintenance without disconnecting the mains electrical
supply.
14. Never attempt to test any samples with a type of grip or other accessory which is not designed
for that particular test, or to use grips or the machine for tests in excess of the stated load limits.
A comprehensive range of alternative grips, together with an applications advisory service, is
available from AMETEK and its Lloyd Instruments accredited dealers.
LR_Plus and EZ Series User Manual

8.2 EMERGENCY STOP
If for any reason the machine needs to be stopped without delay, an emergency stop mushroom is
provided. Pressing this switch stops the LRX Plus immediately. It can be released by turning a
quarter of a turn clockwise. The machine will then restart if the ON/OFF switch is already ON.
8.3 SPLINTER SHIELDS
Transparent splinter shields are available as an option to enclose the test sample if there is any
danger of samples shattering as a result of the test. These shields can be fitted with an electronic
interlock so that the test cannot be started until the hinged shield is closed. While not mandatory for
many applications and countries, Lloyd Instruments strongly recommend that users consider fitting
this optional item.
If a shield fitted with electronic interlock is used, the following screen will appear if the door is opened
during a test.
Error Condition
Splinter Shield Open
Press Enter to Cancel
The test in progress will be aborted and the next test or a new test will have to be started.
8.4 LOWER ANCHOR PIN ADJUSTMENT
The Lower Anchor Pin has two locking collars, one to lock it in position in the lower (fixed) crosshead
and the other to screw upwards to lock the bottom grip / fixture firmly in position.
When the grips or test fixtures have been fitted to the loadcell and bottom anchor pin, carefully align
the top and bottom grips or test fixtures. Turn the bottom collar clockwise until it is locked against the
lower crosshead in the position required.
Extreme care must be taken when manoeuvring the crosshead, particularly when low force load cells
are being used as they can easily be damaged even at moderate speeds. As an additional precaution during compression testing the lower hardware limit stop should be set so that the compression
plates cannot come together either during or after a test.
Screw the bottom collar clockwise until it
is flush with the base plate and locks the
Lower Anchor Pin in position.

8.5 LIMIT STOPS
The Lloyd Instruments machines are fitted with two magnetically activating limit stops. These can
be used as extra protection to stop load cells, grips or fixtures coming into contact. The upper one
can be used to back up the software limit. Reaching magnetically activated limit stop will result in the
machine stopping.
Adjustable Upper Limit Stop
Adjustable Lower Limit Stop
Adjustable Top Limit Stop
To adjust the bottom limit stop, drive the moving crosshead to the lowest position that it is ever going
to get to safely without damaging any fitted grips or fixtures. When this position has been reached
drive the crosshead up by 3mm. Move the lower adjustable limit stop up to the crosshead actuator.
To adjust the top limit stop, drive the moving crosshead to the highest position that it is ever going to
get to safely without damaging any fitted grips or fixtures. When this position has been reached drive
the crosshead down by 3mm. Move the upper adjustable limit stop down to the cross head actuator.
If during a test or when manoeuvring the crosshead, a limit stop switch is activated, a display as
shown below or similar will be seen.
Error Condition
Lower limit switch
Press Enter to Cancel
When ENTER has been pressed and this display has been cleared the machine will only allow the
operator to drive the crosshead away from the limit stop.

10.0CLEANING AND MAINTENANCE
10.1CLEANING EXTERNAL FINISH AND TRIM
The finish and appearance of your machine can be maintained by regular cleaning with a damp cloth
containing a small amount of mild detergent. The machine should be turned OFF and disconnected
from the mains supply whilst cleaning is taking place. Strong proprietary cleaners and petroleum
based or other solvents should not be used.
10.2MAINTENANCE
In normal use and conditions, your machine should be serviced and calibrated annually by AMETEK
or one of their appointed Lloyd Instruments agents. There are no user serviceable or adjustable parts
within the machine, therefore service and calibration should only ever be undertaken by engineers
trained for the task.
If the machine is being used in a particularly arduous way or under extreme conditions, your
appointed service agent may recommend more frequent calibration/service.
CAUTION: Take care to use only a damp cloth. NO moisture must ever be allowed to
get into the machine. Wipe the machine dry before connecting to the mains supply and
restarting.
