range

The horizontal axis (time axis) range is calculated
from the frequency and cycle.

f [Hz] =1/t [s] (f: frequency, t: cycle)

Example: When the meas urement frequenc y is 50 Hz.
E.g. 1 cycle is t= 1/50 [s], i.e. 20 ms.
When the horizontal axis (time axis) is set to 20 ms/

Convenient functions

What is a pre-trigger?

It is a function which allows waveforms before the trigger point to be recorded.

Merit Useful to detect signs before abnormal occurrences happen because parts

before the trigger point are recorded.

If the pre-trigger
is not used...

Using the pre­trigger allows
the user to
observe the part
before the
abnormal
occurrence.

If the pre-trigger is not used, only the parts after the trig ger point are recorded.
User will be able to see the abnormal occurrence but will not be able to detec t
any signs before that.

When the pre-trigger is used, the parts before the trigger point are recorded,
allowing the user to detect signs before the abnormal occurrences happen.

Signs are very likel y to be present b efore any abnor mal occ urrence or dist ortion
happens.
Using the pre-trigger of the Memory HiCorder, users can observe the parts
before any abnormal oc currences, and find out the reason why accidents an d
production faults happen during which type of waveforms.
The trigger funct ion is recom mended to p reven t acci dents a nd faul ts and loss es
due to such occurrences.

About the Screen

The inst rum ent’s LC D pr ovi des SVG A ( 800 × 6 00) reso lut ion . Th e wa ve­form display area consists of 625 horizontal dots and 500 vertical dots.
The waveform display area is divided into 25 divisions horizontally, and
20 divisions vertic ally, with each d ivision comp osed of 25 d ots ho rizont ally
and vertically.
Each data frame (one division) represents 100 samples horizontally, and
80 to 1600 data bits vertically. (depending on the input module)
Each displayed data frame (one division) changes in accordance with
expansion and compression of the time and voltage axes.

Recording Length Setting

Set the length (numb er of divisions) to recor d each time data is acq uired. Each division of the recording
length consists of 100 data points. The number of data points of the whole recording length is the specified
recording length (d iv is io ns ) × 100, + 1.
Example. The number of data points when the specified recording length is 50 divisions:
50 div × 100 data points + 1 = 5001 data points
