* Comparison with Yokogawa’s previous model WT1600
A new range configuration function is available. It allows you to select a
particular voltage and current input range (effective measurement
range). Eliminating unnecessary ranges has made it possible to achieve
optimal range setting that is faster than Yokogawa’s previous model*.
This allows more quicker tracking of signal changes.
If the peak goes over the limit, you can switch to a preset range. This is
effective in reducing the production time for a repeat test, such as
setting to OFF, 100 V, OFF and so on, which is performed frequently on
the production line.

A harmonic measurement option (/G5) makes it A
possible to display both numerical data and bar
p
graphs to help understand measurement data
g
visually.
v
In addition, a dual harmonic measurement
I
function (/G6) makes it possible to measure
f
and display two-line harmonic bar graphs (dual
a
harmonic) simultaneously.
h
A high resolution display makes is possible to
split the waveform display into up to 6 split
screens. This makes it possible to split the
display of signals between the input and output
of a three-phase inverter and display them
simultaneously.
Waveform display allows you to display
waveforms for the voltage alone or the current
alone, or arbitrarily set the display position, so
you can also display only the signals you want
to compare one above the other.
The /G5 or /G6 option is required T

Fundamental harmonic voltage and current F
signal phase vectors can be displayed. With
s
Yokogawa’s previous model, vector display is
Y
limited to a single line. With the WT1800, Dual
l
vectors can be displayed.
v
In addition, combination display of vectors and
I
numerical values is also possible. This allows
n
you to view the numerical parameters and
y
voltage and current phase status visually.
v
The screen can be split into two, with one
above the other, and two types of screens can
be displayed simultaneously. Screen can be
selected from Numerical, Waveform, Trend, Bar
Graph, and Vector displays.
Another new function allows you to press the
NFO button on the Numerical screen to display
the setting information in the upper row and
automatically scale down the numerical
nformation displayed in the lower row.
mage data can be loaded onto the screen and
the position and size of the numerical data can
be specified.
The display screen can be customized so that
the corporate logo of your company is displayed
on the screen, or only the measurement items
you want to view, such as input and output
efficiency or frequency, are displayed one above
the other.
When evaluating inverter efficiency, sometimes
small efficiency changes can hardly be
recognized with just numerical values.
Trend display makes it possible to display
measurement values and measurement
efficiency as trend data in time series to help
capture even small changes visually. Trend data
over several minutes or several days can be
displayed.
*Trend display can be saved with the screen hardcopy function.
To save numerical data, a store function is used.
