3.1 Unpacking the Stand
When you first receive the stand please check that there is no obvious damage to the
packaging. If there is any sign that the packaging or the test stand itself has been damaged,
please contact Mecmesin or your authorised distributor immediately. Do not use the stand
until you have done so.
We strongly recommend that the packaging is retained, as this can be useful if the machine
needs to be returned for calibration or shipped between sites.
Section 1 lists items that should be included with your test stand. Please contact Mecmesin or
your authorised distributor if any items are missing or damaged.
3.2 Lifting the Test Stand
The unpackaged weight of the test stand is given in the specification table at the back of this
manual. Do not try to lift heavy loads unaided. It is advised to use suitable lifting equipment
when moving your OmniTest-5.0 system.
3.3 Environment Conditions
In line with BS EN 61010-1 it is recommended that your Mecmesin OmniTest-5.0 test stand is
operated in an environment that matches the following conditions:
•Indoor use only, recommended to be operated in a lab environment.
•Altitude up to 2 000 m;
•Temperature range between 10 °C to 40 °C. Please note that the instrument should not be
used for long durations at higher temperatures.
•The maximum relative humidity is 80 % for temperatures up to 31 °C decreasing linearly
to 50 % at 40 °C. It is crucial that the surrounding environment does not cause water to
form on the device.

3.6 ELS: Enhanced Load Sensor
Enhanced load sensors or ELS for short, are smart devices used to capture load readings for
OmniTest-5.0 test stands, all calibration information is held on the individual load cell
meaning they can be swapped from system to system and the calibration will follow with no
input required.
These load cells are available in a range of sizes and designs to best suit your requirements.
See the specifications section of this document for details relating to capture rate and accuracy.

3.7 Fitting an ELS to your Test stand
The OmniTest-5.0 has a dovetail bracket attached to the moving crosshead, which tightens by
using an Allen key on the embedded screw.
To fit your ELS to your test stand slide the load cell sideways onto the dovetail and tighten
the grub screw (circled below in red) located in the dovetail using a suitable Allen key.
To prevent damage, do not over-tighten the grub screw in the dovetail when a gauge bracket
is not present.
OmniTest-5.0 Dovetail, note the grub screw circled in red
Note: Take care when handling low capacity ELSs such as a 5N cell, as damage can easily
occur from mishandling.
It is also important to ensure that attached grips and fixtures do not overload the ELS. If in
doubt please check the weight of any addition grips and fixtures prior to fitting these.

10 Mecmesin OmniTest-5.0 Operating Manual
Connecting an ELS to the OmniTest-5.0
To connect your ELS to your OmniTest stand simply plug the 6-pin connector located on the
machines crosshead into the ELS fitted.
Connecting the 6-pin plug to the ELS
As enhanced load sensors are ‘smart’ devices all calibration and capacity information is
passed to the stand automatically as the sensor is connected.
3.8 Connecting the OmniTest-5.0 to a PC
To connect your OmniTest-5.0 test stand to VectorPro™ MT software, connect the USB B port
to a PC using cable part no. 351-093.

3.10 Setting the Limit Stops
Limit stops help prevent damage to load cells and fixtures by stopping the crosshead
movement before the moving fixtures come into contact with static parts of the stand. Their
positions are adjusted after the fitting of fixtures and test samples.
There are two manually-set limit stops, located for your convenience, on the front of the
OmniTest-5.0. These are set by loosening the thumb-screw, moving the stop to a new position
and retightening. When the crosshead meets a stop, it activates a switch. This will stop
crosshead movement at an upper or lower limit.
Limit stops on an OmniTest-5.0
3.11 Test Stand States
The test stand can be in one of five states:
1. Test readiness - ready to start, or complete,
2. Testing – test operation sequence is running,
3. Stopped - test interrupted or emergency stop pressed,
4. Jog mode - for jogging or positioning the crosshead manually,

Jog Mode
When in jog mode the wheel drives the crosshead directly up (clockwise) or down
(anticlockwise). This offers more variable control when compared to the two fixed speed jog
control buttons (circled in red below).
The scroll wheel can also be used as a speed controller. The jog buttons move the crosshead
at the set speeds (configured in the ‘Jog Settings’ menu picture below), but rotating the wheel
clockwise whilst holding a jog button will increase the speed and rotating the wheel
anticlockwise whilst holding a jog button will decrease the speed.
OmniTest-5.0 test stands also feature a precision jog mode, rotating the scroll wheel while
holding the central scroll wheel button moves the test stand at its minimum speed, this is
useful when fitting specimens into grips for example.
Navigational Control
The scroll wheel can also be used to navigate the menus. When in a selection menu, the scroll
wheel cycles through the selections and their values. This is an alternate navigational option
to using the up and down arrow buttons.
The Button
The central button is used to confirm a menu selection. It is equivalent to the tick button.
It can also be used to activate fine jog control, by rotating the scroll wheel while holding the
central scroll wheel button moves the test stand at its minimum speed.

5. Automatic ELS Firmware Update
All OmniTest-5.0 test stands with firmware 3.1.0.0 and above have the ability to update the
firmware of any ELS device. This feature is seamlessly managed through the front panel and
ensures that the latest firmware is on your ELS devices.
Step 1 - Connect Your ELS Device
To start the update connect your ELS to your test system, then switch the test stand on.
Note: Analogue short travel extensometers can also be updated in a similar method, simply
plug the extensometer device in to the corresponding connector on the rear of your OmniTest.
Step 2 – Starting the Upgrade
On the display located on the front panel of the test stand you will be presented with the
following screen.
The new ‘Stored’ firmware is listed at the top of the display and the current ELS firmware is
display below. In this instance the ELS current firmware is 1.0.4.7, starting the update will
flash the device to version 1.0.6.1. If more than one ELS is connected (load cell and a short
analogue extensometer) the additional device will be listed below ELS 0. To start the update
of the first ELS device press the ‘tick’ icon.

Step 3 – Flashing the Device
The flashing of the device is carried out automatically and progresses through several stages.
It is important that the test stand is not turned off or disconnected. Disconnection of the ELS
could lead to irreversible damage.
In the image above initial programming is taking place. You can monitor the progress using
the bar and percentage readout below.
Within the final stage of the process the firmware upgrade is verified to check that is has
completed successfully.
Once the process is at 100% the display will indicate that the firmware upgrade has been
successful. You will then either be prompted to update the next ELS device currently connect
or the display will return to the start screen, if no additional ELS devices are connected.
You can check the version of the ELS firmware manually by accessing the ‘Information’ screen
located in the ‘Settings’ menu, See Section 6 for more information.
