6) Rotate the Solid Standards until
they set into position.
Note: You will feel/hear a click
when the Solid Standard is
positioned.
7) Adjust the Solid Standard to
produce the same fluorescence
output value from the sensor as in
step 1.
To adjust each solid standard, use
the green screwdriver to unscrew
the locking nut as far as it will go.
To change the signal level, insert
the green screwdriver through the
hole in the locking nut. Rotate it
until it engages with the
adjustment screw that is beneath
the locking nut.
The signal can be adjusted to
desired reading by turning the
screw.
Once the desired reading has
been obtained, the locking nut
should be screwed down so that
the adjustment screw is held firmly
in place.
Note: The response of every
solid standard is unique.
Hence, a new correlation must
be determined for every sensor.
8) Now your Solid Secondary
Standard has been correlated to a
known concentration and as long
as it is no longer adjusted and is
stored and used properly that
signal will remain a stable
reference point.

fluorescence please refer to the
