waveforms
When performing FFT analysis of data measured with
the memory function, you can use the jog shuttle to
specify analysis points while also viewing the calculation
results at the same time. You can also display both the
raw data measured with the memory function and the
calculation results for storage waveforms at the same
time, which improves operability during analysis by
displaying spectrum waveforms while checking the
results of window functions.

MEMORY HiCORDER MR8847A
X-Y RECORDER
Now even easier to use with independent pen up/
down control. Saving data in chronological order
allows records to be saved as digital data, rather than
paper hardcopies that need to be stored.
Pen up/down control
Pen up/down during X-Y recording is controlled
independently. Press the function button or use an
external control terminal (EXT. IN 1, 2, 3) for external
control.
Replaces mechanical pen recorders
Use pen up/down control to record only the required
data. T his allows you to reduce the amount of
unnecessary data that is recorded, and lower the
running cost for paper.

Control terminals
Determine waveform quality
Use the waveform judgment function, which monitors
whether a waveform extends beyond the given area,
to easily determine the quality of signal waveforms
that are normally difficult to judge.
For time axis ranges that are slower than 100 msec/
div, you can even make judgments while loading
waveforms. This allows you to take the appropriate
action the moment a poor waveform is detected on
the production line. You can stop the line as soon as
an abnormality is detected.
Judge FFT analysis waveforms
Judge FFT analysis waveforms in the same way.
Judge waveform quality by area
Judge X-Y waveforms
In addition to time axis signals, the MR8847A also
has a waveform judgment function for X-Y waveforms
built in. Use this to detect:
- Displacement and pressure of presses
- Pressure and flow rate of pumps
The X-Y waveforms of the above and other data can
be tested automatically based on area judgment.
