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.

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 and
autologging options. For more details on the different functions of the utility toolbar refer to section 7.

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 displays between absorbance or % transmittance.
5.2.1
Selecting a Wavelength
The wavelength can be adjusted in the operating menu 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.
