6.2 KEYPAD OPERATION AND
DESCRIPTION
The keypad has 25 keys arranged into 4 groups.
The rst group contains 8 keys in the bottom
right hand corner of the keypad
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. 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.
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
a fast 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 nal 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.
NOTE: The STOP key is not to
be used for EMERGENCY STOP
conditions. The Emergency Stop
key is located on the left-side of the
machine base.
