SPECTROPHOTOMETER MENU OPTIONS
SECTION 5 – Photometrics
The photometrics measurement mode enables simple measurements of absorbance and % transmittance
to be performed. The sample is measured at one wavelength and at one point in time. There are no post
measurement calculations available in this measurement mode.
5.1 MODE SPECIFIC PARAMETERS
The photometrics operating menu enables measurement
parameters to be changed. The utility toolbar on the left
hand side of the screen enables access to printing, print
setup options, results, methods and autologging options.
For more details on the different functions of the utility
toolbar refer to section 17.

5.2 METHOD SET UP
This measurement mode is very simple and the only
parameters which can be adjusted are the wavelength and
the display format.
The toggle icon enables the large primary display to be set
to show the absorbance or % transmittance.
To change the primary and secondary displays press the
key adjacent to the toggle icon. Repeat presses will cycle
the display between absorbance and % transmittance.
5.2.1 Selecting a Wavelength
The wavelength can be adjusted by using the keys adjacent to the arrow icons to increase or decrease
the wavelength. Once the required wavelength has been selected a calibration can be performed.
