9. Method of Starting Measurement
The following conditions should be met for the F395 to display input signals from the
strain gauge sensor as a waveform on the screen and start measurement. (For details of
input and output signals, see "4-3-2. Input and Output Signals" P25.)
i. The START signal turns from ON to OFF.
ii. The input signal crosses over the Waveform Start Level.
(Only "i." when the signal "Capture start by external signal" is ON.)
Waveform drawing ends when the STOP signal turns ON, or when 2048-point sampling
is exceeded, or when the input signal crosses over the Waveform Termination Level with
the signal "Waveform termination level operation" ON.
The relationship between the input signal, START / STOP signal, and waveform drawing
(sampling) is as shown in Example 1 ~ 5 below.
Example 1
* If a HI or LO alarm is given at the same time when waveform capturing ends, the
waveform is registered in the Rejected Waveform Area.
