Press the CAL key to set the display to 0.000ABS or 100%T. Insert the
filter or standard in the sample chamber and close the lid.
Press the up arrow key to increase the wavelength by 1nm and check that
an Absorbance value has increased or a Transmission value has
decreased.
Repeat the above until the first Absorbance value decreases or the first
Transmission value increases. At this point press the down arrow key and
check that the previous value is attained again. Then record this
wavelength as the reported peak.
Repeat the above and check that the same value is reported.
NOTE:
1.) If it is known that there are other peaks closer than 10nm
to the certified peak then the start wavelength should be moved closer to
the certified peak just past any others.
2.) If the Absorbance display goes over range during the test
then carry out the Calibration at the initial wavelength with the filter or
standard in the sample chamber.
Calculate the adjustment required to correctly align the reported figure
with the certified value from the following...
Certified Value – Reported Value = Correction factor (can be negative or
positive, maximum correction permissible is 3.0nm)
Switch the unit off and re-start it in the Diagnostics Mode by holding
down the right hand arrow key <>> while turning power on.
The display should show a mV reading on the top row, followed by the
wavelength on the 2
nd
row and %T at the bottom left hand side.
Pressing the right arrow key again [>] should operate the dark shutter
solenoid. Press this key to ensure that the shutter is in the open position
(the position that gives a maximum reading on the display)
Press the down arrow key until the wavelength display reads 0.0. Press
the left arrow key to dim the lamp.
Use the up and down arrow keys to set the display to the correction factor
calculated above (observe polarity)
