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 flashing
“slope” icon superimposes on the „wait” icon.

Level trigger
The Level+ / Level– trigger starts the 1-second measurement/integration under
the condition: value of the RMS result (Source) integrated 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 mc.
When the new measurement cycle begins (after pressing the <Start> key or automatically after stop of
the previous measurement cycle) 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 trigger condition checking every
0.5 ms and starts next 1-second
integration if condition is met. The
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 <Start/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.
Note: When a measurement is waiting for the level trigger, the flashing
“level” icon superimposes on the „wait” icon.
