MEMORY OPERATION
The
Ultra Measure Master
has ten storage
registers (0 through 9). Memory 0 is a
cumulative memory which operates similar
to a standard
µ
key, while the other
memories are used for storage only. A
value can be stored in any format, but
attempts to add mixed conventions will
result in an error (the value in memory will
not be revised). Memory 0 will keep its
value until it is revised (as shown below),
or the calculator is shut off. Memories 1
through 9 will keep their values even when
the calculator is shut off. Keystrokes for
operation are as follows:
