move to 10 mm above tared zero, followed by a final movement back to -20mm.

AFG Control/Force Control

The AFG control test operation consists of two main functions:

 AFG Control - Control of the test stand using the AFG’s limit or break settings,
 Force Control - Control of the test stand using the front panel to program limit,

break or cycle settings,

Within AFG Control/Force Control there are four subtests:

Sub-Test Description

AFG Control

Move in a set direction until a force limit or break condition is hit
and then stop. Configured using the AFG.

Force Limit

Move in the configured direction until a force limit is hit and then
stop. Configured using the front panel.

Force Cycle

Cycle between a limit force and a return force. Configured using
the front panel.

Break

Move in the configured direction until a break condition is detected.
Configured using the front panel.

AFG Control Test

With an additional cable (351-092), a Mecmesin AFG digital force gauge can be used to
set load limits to control crosshead movement.

Load setpoint, action (reverse/stop) are all set on the gauge under the ‘STAND’ menu.
Here you can select the action when the limit is reached; ‘REVERSE’ or ‘STOP’ and the
type of control limit ‘BREAK’ or ‘LIMIT’.

Please note for cyclic tests the front panel force control must be used. AFG cycling is not
compatible with MultiTest-dV test stands

Example Test Setup

1. On the test stand’s front panel under ‘Edit Test’ select the test type ‘AFG Control’
and sub-type ‘AFG Control’,

2. Configure the speed and direction settings located within the ‘Edit Test’ menu,

3. On the AFG gauge hold

4. On page one of the AFG menus select ‘STAND’ using the button,

5. Next select the action when the limit is hit, either ‘REVERSE’ or ‘STOP’. For

reverse you need to select the test direction either ‘UP’ or ‘DOWN’,

6. Once the action has been selected configure the limit control. This limit can be
either a ‘BREAK’ condition or force/torque ‘LIMIT’. For ‘BREAK’ set the break
threshold, for ‘LIMIT’ select the limit force/torque,

Force Control Test – Force Limit, Force Cycle and Move to Break

Force control tests can be used to set load limits or a break condition to control crosshead
movement.

Within the three sub-tests (Force Limit, Force Cycle and Move to Break) the following
settings are available, please note some of the settings are specific to the test type:

Setting Options

Up Speed 0-1200mm/min

Down Speed 0-1200mm/min

Examples

Force Limit

 Up Speed: 100 mm/min

 Down Speed: 100 mm/min

 Start Direction: Down

 Test Sub-Type: Force Limit

 Limit Force: 50 N

The crosshead moves down at 100 mm/min until the applied load is 50 N from tared
zero, once the limit force is reached the test stops.

36  Mecmesin MultiTest-dV Operating Manual

Force Cycle

 Up Speed: 100 mm/min

 Down Speed: 20 mm/min

 Start Direction: Down

 Test Sub-Type: Force Cycle

 Limit Force: 200 N

 Return Force: 50 N

 Cycle Count: 10

The crosshead moves down at 20 mm/min until the applied load is 200 N from tared
zero. Once the limit force is reached the crosshead moves upward at 100 mm/min until
a load of 50 N is reached, this cycle repeats 10 times at which point the test stops.

Break

 Up Speed: 50 mm/min

 Down Speed: 100 mm/min

 Start Direction: Up

 Test Sub-Type: Break

 Break Threshold: 5 %

The crosshead moves up at 50 mm/min until a break condition is detected. The break
event must also occur above 5% of the connected AFG’s capacity.

Data Capture within VectorPro™

To use AFG Control/Force Control tests in conjunction with VectorPro first program
the test settings using the stand’s front panel and/or AFG and then create a VectorPro
test using the AFG/Force control operation, ensuring the speed and test direction match
your configuration.

Please note the speed and test direction use the settings configured within VectorPro,
while other test settings are loaded from the front panel. For more information please
refer to the VectorPro user manual, part no. 431-955.

Limits

In a limit test, the crosshead cycles between the limit switches. To set your limit switches
loosen either screw, located on the rear of the test stand, and move the switch to the
required position.

A cycle starts when the crosshead is at the first limit switch and ends back at the same
limit switch. At the end of the test, the home button appears on the stand to enable the
crosshead to be moved back to the starting position.

Setting Options

Cycle Count 0-9999

Up Speed 0-1200mm/min

Down Speed 0-1200mm/min

Start Direction Choose whether the test direction is upward or downward.

Move to Start Select if the test moves to the start position first.

Example

1. Load your grips and sample,

2. Set the upper limit switch at the desired upper displacement point,

3. Set the lower limit switch at the desired lower displacement point,

4. Set the desired start direction and whether to move to start,

5. Configure the number of cycles,

6. Execute the test. The stand moves between the two displacements for the configured

number of cycles and then stop.

38  Mecmesin MultiTest-dV Operating Manual

Half Cycle

A half-cycle test is to a displacement relative to tared zero. A cycle starts when the
crosshead is at the first displacement position and ends back at the second position.

Setting Options

Cycle Count

0-9999

Up Speed

0-1200mm/min

Down Speed

0-1200mm/min

Upper Displacement

A positive displacement is above tared zero and a negative value is
below. Available displacement depends on the test setup.

Lower Displacement

A positive displacement is above tared zero and a negative value is
below.

Start Direction Choose whether the test direction is upward or downward.

Move to Start Select if the test moves to the start position first.

Example

Upper displacement: +30 mm

Lower displacement: –20 mm

Initial stroke: Down

Move to Start: Yes

Unless already at 30 mm above tared zero, the crosshead will travel to that point and
then move to 20 mm below tared zero, and stop.

MultiTest-dV Operating Manual Mecmesin  39

MultiTest-dV Operation Sequence and Move to Start

MultiTest-dV operations, such as the displacement cycle and half cycle consist of two
datum points, an upper displacement and a lower displacement.

For operations with the primary direction being down, the following is true:

 The ‘Upper Displacement’ is the start position for the test and the ‘Lower

Displacement’ is the finishing position.

For operations with the primary direction, being up the following is true:

 The ‘Lower Displacement’ is the start position for the test and the ‘Upper

Displacement’ is the finishing position.

Within the ‘Edit Test’ display on your test stands front panel there is an option called
‘Move to Start’, setting this feature to ‘Yes’ means that the stand always moves to the
start position.

In some instances, this means the first direction of movement is opposite to the primary
test movement.

For example, if the start displacement is +10 mm and the crosshead is at 0 mm, with
move to start enabled a downward test will first move up to +10 mm before moving
down to the end position. With this feature set to ‘No’, the stand moves straight to the
end position.

Settings: PIN Code

Within the PIN code menu, it is possible to set a four-digit number that can be used to
