Atec Zimmer-LMG450 - Manual (Page 2)

General The four-channel LMG450 power
meter is another advanced
product from ZES ZIMMER
LMG series of precision power
meters, tried and tested and
with great acceptance in the
market. It is designed as a uni-
versal meter for the entire field of power electronics and net-
work analysis. It can be used in
practically all power electronics
applications, in development
and test systems, in quality as-
surance and maintenance.
It is fully frequency inverter
compatible. Of course, it can also be used
for measurements in motors,
transformers, conventional and
switched power supply units.
It is also suitable for mains
analysis measurements.
Easy operation thanks to
colour graphics display and
hotkeys for important
measured values
Various value tables can be
called on the colour graphics
display at the press of a key,
either with six values in large
letters, which can also be read
at a glance from a greater distance, with twelve values
or with up to 40 values e.g. in
range setting or in harmonics
table. The graphics display
allows scope and plot functions
for waveform and timing dia-
grams, as well as xy diagrams or
bar charts for the harmonics.
The status bar at the top of
each display menu shows the input level of the four voltage
and the four current inputs – an
important item of information
for the quality of the measure-
ment.
The display also indicates what
groups, A and B, the input
channels are switched to and
which signals the groups are
synchronised to.

Measurement inputs The direct measurement inputs
for voltage and current have a
very wide dynamic range:
Eight voltage ranges from 6V to
600V, and six ranges for current
from 0.6A to 16A.
A further voltage input (six ranges from 0.12V to 4V),
designed for isolating current
sensors, extends the current
measuring range almost in-
definitely. With the help of the
special current clamps supplied
by ZES ZIMMER and designed for the LMG450, current can be
measured during running opera-
tions, without interrupting the
current path.
