1 LEARNT PROGRAM

CILITIES
The 1253 can store a sequence of measurement instructions for execution when required.
These Learnt programs are useful where test sequences must be duplicated a number of
times, for example in production testing.
One instruction is equivalent to a single menu selection. A typical comprehensive program
uses less than 50 instructions, each instruction using one memory block.
Section 2 describes the programming facilities that are available. A simple example is
given in Section 3, which provides a useful introduction to programming.
1.1 THE PROGRAM STORAGE AND SIZE
Up to 9 programs (numbered 1 to 9) can be stored in battery maintained memory along with
the front panel (menu) settings.
These programs remain in memory for typically 1000 hours after the main supply is
removed, but are ‘refreshed’ whenever mains power is re-applied. A full recharge takes up
to 12 hours.
The maximum amount of memory that is available for storing learnt programs is
approximately 300 blocks. The actual amount is determined by number of blocks allocated
to the History file.
