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:

(Cont’d)

1 2 ... 18 19 20 21 22 23 24 25 26 27 28 ... 51 52
