8 Taking a reading with a Sola-Sure
8.1 Scan Settings
8.1.1 Intensity Range
The
Intensity Range
settings sets the maximum
Intensity
that the sensor can read
before
saturation
occurs. Set the
Intensity Range
to value just above the peak output
Intensity
of the lamp to be measured for optimum performance. If the peak output
Intensity
of the lamp is unknown an
Auto-Ranging Scan
may be performed (see
later).
(NOTE – The lower the
Intensity Range
the longer the
Sample Time
.)
8.1.2 Optimisation
The
Optimisation Level
sets the number of scans taken by the Sola-Sure during a
single reading to improve the accuracy of the lower
Intensity
sections of the
spectrum. The
Optimisation Level
can be set from 1 to 7, each scan taking half the
time of the scan before it. The first scan will take

For example if the

and the

is set to 3 then the overall maximum

seconds.
This is a maximum
Sample Time
because if the first scan does not
saturate
then the
Sola-Sure will not take any more readings as it already has all the data it needs.
As a general rule, the shorter wavelength accuracy can be improved by increasing the
Optimisation Level
. A faster reading can be obtained by reducing the
Optimisation
Level
. The default
Optimisation Level
is 5.
8.2 Taking a Standard Scan
A
Standard Scan
will scan using the currently set
Intensity Range
.
•
To take a
Standard Scan
simple press the
Scan Key
.
•
The
Clock
icon will count down the number of minutes and seconds left
before the scan finishes.
•
When the scan finishes the three LEDs on the front of the Sola-Sure will flash
twice.
8.3 Taking an Auto-Ranging Scan
An
Auto-Ranging Scan
is used to set the Intensity Range of the Sola-Sure if the
required
Intensity Range
is not known.
•
To take a
Auto-Ranging Scan
simply press and hold the
Scan Key
for two
seconds.
