Performing a Measurement
Having selected the required wavelengths from the SET UP menu the instrument is now ready to
perform a measurement.
Open the sample chamber lid and place the blank sample in position. Close the sample chamber lid
and press the Cal key. The display will momentarily show - Calibrating Dark Level, Calibrating
Light Level and then Reading Sample at the set wavelength. This will be repeated for the second
wavelength measurement. The display will then update to show 100.0%T or 0.000Abs, depending
on mode selected.
Remove the blank sample from the sample chamber.
The instrument is now ready to perform a measurement.
Place the unknown sample into the sample chamber and close the lid. Move the cursor to SAMPLE
using the RH key and press to confirm. The instrument will now measure the sample at the
selected wavelengths and, when completed, the lower portion of the instrument display will update
to show the sample value directly as %T or Absorbance, as appropriate.
