The

application

program

"DMM"

permits

you

to

use

the

CMT-300

system

as

a

digital

multi-

The

front

panel

of

the

multimeter

is

defined

by

the

keyboard

overlay

provided

with

your

CMT-300.

The

multimeter

labels

are

on

the

right-

hand

side

of

the

keys.

To

"turn

the

multimeter,
