Jenway 7305 - Manual (Page 20)

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 minimal operating menu enables
calibration to zero absorbance/100% transmittance
and simple readings to be taken without changing any
measurement parameters. Pressing the key adjacent to
the
JW icon opens the expanded operating menu.
The photometrics expanded 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.

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.
