Pre and post trigger logging
In the Pre Trigger position, you can define the number
of logger results which will be registered in the file before
fulfilment of the first trigger condition. This number can
be set in the range 0..10.
In the Post Trigger position, you can define the number
of logger results which will be registered in the file after
fulfilment of the last trigger condition. This number can
be set in the range 0..200.
Periods of logging the logger results before and after fulfilment of the trigger condition can be calculated
by multiplying the value set up in the Pre or Post positions by the value set up in the Logger Step
position (path: <Menu> / Measurement / Logging / Logger Setup). The result of this calculation is
presented in the same line for the Pre and Post parameters in the format 0m00s.
These parameters can perform double role. Firstly, when you wish to collect data right after or before the
event that caused logger trigger. Secondly, when it is necessary to have continuous logging, but the
source is oscillating near the threshold level. The extension of the registration window allows to avoid the
effect of pulsation.
4.5.4 Configuring signal recording – Wave Recording
The Wave Recording position enables activating and
configuring a waveform signal recording in the separate
file with the extension WAV. WAV files are saved
automatically in the working directory of the instrument’s
memory (SD-card).
Note: In the Simple interface mode, the Wave Recording position is hidden, but the
instrument will use settings previously defined in the Advanced mode or default settings
(Recording: Off).
Note: The Wave Recording function is optional and should be unlocked by entering the
activation code in the text editor screen, opened by the â–º key. Once unlocked this option will
be available permanently.
The Recording position, if it is not Off, defines the way a
signal recording should be done, continuously during
measurement (Continuous) or on trigger: Slope+,
Slope -, Level+, Level–, Gradient+, Trig.manual or
Integr. Per. Default mode: Off.
Note: The Wave Recording function is optional and should be unlocked by entering the
activation code in the text editor screen, during the first attempt to switch it on with the â–º key.
Once unlocked this option will be available permanently.
The File Name position enables editing the name of the
WAV file.
In the Format position, you can select the format of the
signal recording: PCM or Extensible.
