The triggering is switched on if any trigger type is chosen in the Trigger position: Slope +, Slope –, Level +,
Level –, Grad + or External. When the trigger is selected, additional parameters can be defined: the
measurement result that is checked for a trigger condition (Source), its threshold value (Level) and the rate of
its changing (Gradient).
Slope trigger
The Slope + / Slope - trigger starts the measurement/integration with the
duration of the Integration Period on condition: rising value of the measured
result (Source) integrated during 0.5 ms passes above/below the threshold
value (Level).
When a new measurement cycle begins (after pressing the <Start> key or automatically after previous
measurement cycle stop) the instrument checks a trigger condition every 0.5 ms and if condition is met the
instrument starts a continuous series of 1-second integrations, the number of which is equal to the number of
seconds in the Integration Period.
After ending the Integration Period, the new
measurement cycle can start with above logic.
The measurement can be stopped manually at
any moment with the <Stop> key.
Note: When a measurement is waiting for the slope trigger, the
“slope” icon appears alternatively with the „measurement” icon.
Level trigger
The Level + / Level - trigger starts the 1-second measurement/integration on
condition: value of the measured result (Source) averaged by 0.5 ms is
greater/lower than the threshold value (Level). In other cases, the instrument
continues checking the trigger condition every 0.5 ms.
When a new measurement cycle begins (after pressing <Start> key or automatically after previous measurement
cycle stop) the instrument checks the trigger condition every 0.5 ms and starts 1-second integration if condition
is met.
After 1-second integration, the instrument
repeats the trigger condition checking every
0.5 ms and starts next 1-second integration if
condition is met. Instrument does it as many
times as many seconds are within the
Integration Period and stops the measurement
cycle. Therefore, the series of 1-second
measurements may not be continuous, and the
duration of the measurement cycle may be
longer than the Integration Period.
The measurement can be stopped manually at any moment with the <Stop> key. Summary Results are
calculated on the base of series of 1-second results measured during each measurement cycle and saved in a
logger file.
