Display Data and Event Data
The measured/computed data are first acquired to the FX100’s internal memory as two
types of data, display data and event data.

• Display Data
Display data are used to display waveforms on the FX100’s screen. The sampling
interval of display data is the time period corresponding to one dot on the screen.
This interval is determined by the display update rate. The relationship between the
display update rate and the sampling interval of display data is as follows:
Display Update 15 s* 30 s* 1 min 2 min 5 min 10 min 15 min 20 min 30 min 1 h 2 h 4 h 10 h
Rate (/div)
Sampling interval 0.5 1 2 4 10 20 30 40 60 120 240 480 1200
of display data (s)
* for the FX103 only
Display data consists of maximum and minimum values of the measured or computed
data sampled at the scan interval within the time period corresponding to one dot on
the time axis on the screen. Display data can be likened to the conventional
recording on the chart sheet and are useful for long-term observations.
See page 1-18 for the display update rate.
• Event Data
Event data is the measured/computed data at specified sampling intervals. The
sampling interval can be selected from the selections below. You cannot specify a
sampling interval that is faster than the scan interval.
FX103: 250 ms, 500 ms, 1 s, 2 s, 5 s, 10 s, 30 s, 60 s, 120 s, 300 s, and 600 s
FX106/FX112:1 s, 2 s, 5 s, 10 s, 30 s, 60 s, 120 s, 300 s, and 600 s
By setting the sampling interval equal to the scan interval, all measured or computed
data sampled at the scan interval can be saved. In addition, the event data generated
when an event occurs (an alarm, for example) can also be saved. This is useful when
you wish to observe the measured/computed data in detail.
