4.1.3 Different measuring modes
There are three different measuring modes available using the Piranha. They are as follows:
The Normal mode is used for short and long (fluoro) exposures. In this mode, your
meter will sense automatically if there is a signal and when it is above a certain
trigger level. If the signal is long, the displays/grid will be updated with new data
every 2 seconds data. If the signal is short, the results are displayed after trigger is
off.
The free run mode has no trigger level. As soon as the meter is told to begin
measuring, it starts to measure even if there is no signal. This measuring mode is
useful when the signal you want to measure is very low. Free run is recommended
for light measurements, especially when measuring "ambient" light (when no
shutter is present).
The Timed mode setting measures during a pre-defined time period.
Measurements in Timed mode must be started manually. This measuring mode is
very useful when you want to measure a very low signal. You can use the "very
high" sensitivity setting in Timed mode and it will further improve the meter's
