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.
