3.3 LEARN mode
70 Metrohm 838 Advanced Sample Processor, Appendix
3.3 LEARN mode
The LEARN mode is used for three types of application:
• Interactive setting of lift and robotic arm positions
• Rack adjustment
• Interactive parametrizing sequence commands
3.3.1 Setting lift and robotic arm positions
The fine adjustment of defined positions, such as the working height of
a lift, can be made by entering the height in mm. But it is recommended
to use the LEARN function to run a lift or a robotic arm to a certain posi-
tion by using the arrow keys of the keypad.
Example: procedure for setting the 'Work height at Tower 1’
• Use manual operation to move to a rack position (at Tower 1).
• Open configuration menu (with the <CONFIG> key).
• Open submenu
>rack definitions and load the data of the rack
which is currently on the turntable.
• Select
work position T1.
LEARN mode
The quicker an arrow key
is repeatedly pressed, the
higher the speed of the lift
or the longer the particu-
lar movement path.
• Press <LEARN> key.
• Use the <> and <> keys to move the lift to the re-
quired position.
• Accept the lift position with the <ENTER> key.
• If necessary modify the position (in mm) by entering num-
bers.
Example: procedure for setting 'External position 1 at Tower 1’
• Use manual operation to move to a sample beaker (at Tower 1)
and move the lift to a suitable lift position.
• Open configuration menu (with the <CONFIG>) key.
• Select submenus
>tower 1 / swing head 1 and external pos.1.
LEARN mode
The quicker an arrow key
is repeatedly pressed, the
higher the swing rate or
the larger the particular
swing angle.
• Press <LEARN> key.
• Use the <> and <> keys to move the robotic arm
until it is in the required position.
• Accept the robotic arm position with <ENTER>.
• If necessary modify the position (in °) by entering numbers.
