MEMORY HiCORDER  MR8847 A

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. 
This allows you to reduce the amount of unnecessary 
data that is recorded, and lower the running cost for 
paper.

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 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.
