21 The LCD/software facility
In addition, if the head is locked in a position which corresponds to
one which has been previously stored in memory, the memory number
will be displayed on lock-up. See section 6.3, ‘Simple mode’ in this
manual for step-by-step instructions.
6.1.3 Memory mode
The user can enter memory mode from simple mode by pressing
either the M+ or M- button. In this mode the MIH memory can be
programmed or used. In memory mode, chosen head positions can be
stored in up to 20 memory stores. Each position is allocated a memory
number (0 to 19). In use, a chosen memory number is selected and
direction arrows on the LCD lead the user to rotate the axis until the
position stored in that memory is achieved. If the user fails to achieve
the selected position, this condition is indicated by the fl ashing of the
direction arrows on lock-up. Once the correct position is reached, the
arrows disappear and the head position confi rmation symbol is shown.
Exit from memory mode will occur after a 10 second period of
inactivity and the head will revert to simple mode. A simple button
press will return the user to memory mode. See section 6.4, ‘Memory
mode’ in this manual for step-by-step instructions.
6.1.4 Sequence mode
Sequence mode can be entered by a 5 second press of both M+ and
M- buttons from simple mode.
In sequence mode, pre-memorised head positions can be arranged
in any order to suit a particular sequence of inspection. Up to 20
sequence position numbers are available and the sequence can be
edited as required. In use, the direction arrows lead the user through
the pre-programmed sequence and will confi rm that the head is locked
in a correct position. The display automatically indicates the next
position in the sequence when the head is next unlocked. See section
6.5, ‘Sequence mode’ in this manual for step- by-step instructions.
