To select Rate highlight the RATE option on the MENU PAGE and press ENTER.
The RATE Methods page is displayed and from here the instrument and analysis
parameters can be set up.
Move the cursor to the required parameter using the Up/Down Arrow keys.
Press ENTER to enable a parameter to be changed.

The Deuterium lamp will be switched on if a wavelength less than 325.0 nm is
selected for a Gamma. Any current data will be lost if the wavelength is changed.
MEASURE TIME
This sets the time over which the sample will be measured. The range is from 5
seconds to 99 minutes and 59 seconds in steps of 1 second.
If the cell programmer is ON then the measurement time sets the time between
individual measurements on the first cell (i.e. the time for each cycle).
DELAY TIME
This sets the time between pressing RUN and the start of the measurement. The
range is from 0 to 99 minutes and 59 seconds in steps of 1 second.
