Daily Light Integral (DLI) Readings
The LightScout
®
Quantum PAR
Light Meter takes a light reading
every 3 minutes to use in calculat-
ing a 24
-
hour Daily Light Integral
(DLI). Every 15 minutes the previ-
ous 24 hours of stored readings
are used to recalculate the DLI.
Readings are automatically taken
whether the meter is on or off, as
long as there is a battery in the
meter. The current DLI value will
be displayed on the LCD for 3 sec-
onds every time the meter is
turned on, including after a power
cycle (off and on).
The DLI calculation can be reset to zero by pressing and holding
both the POWER and SCAN buttons simultaneously until you the
DLI value changes to 0.0. The integration and calculation of DLI will
start accumulating a new 24 hours
’
worth of 3
-
minute readings from
that point forward.
