Time waveform mode
Graph display:
X axis: 201 display points are used to represent
all waveform sample data
Zoom function allows expansion of display
according to number of samples, as shown
in table below.

2048 (800) ×1 to ×8
4096 (1600) ×1 to ×16
8192 (3200) ×1 to ×32
Y axis: Linear display only

Memory
Memory media SD cards (max. 2 GB)
Data store les Vibration meter data store le, waveform data store
le, FFT data store le
Up to 1000 data store les can be saved under one store
name, up to 100 store names allowed
WAV E les Stored by waveform recording function along with FFT
data
BMP les Screen capture data can be saved as BMP les.
Parameter setting memory
Up to ve sets of measurement parameter sets can be
saved in the memory of the unit. Five sets can be stored
as a group on SD card and loaded back into the unit.
Swapping the current settings for saved settings and
vice versa is possible.
Recall function Measurement data can be read from SD card and
redisplayed on screen.
FFT analysis of stored time waveform data on the
VA-12 is not supported.
