3.6 KINETICS MODE
Having selected Kinetics Mode from the Main Menu options the following display will be shown:
Kinetics Pre-Measurement Menu
Mode
Takes the instrument back to the operating mode menu.
Set-up
Allows access to the kinetics mode set up menu and instrument set-up menu.
Start
Begins a kinetics run. This commences with a lag time wait or wait for the absorbance or transmittance
to reach a user set level (if this feature is enabled). After the lag time, or when the level is reached (if
enabled) then the run time commences. Readings of absorbance or transmittance are taken and displayed
graphically at a time interval of 0.5% of the user set run time, until the total run time has expired. For
example, if the run time is set to 60 seconds, readings will be taken every 0.3 seconds.
It is recommended that set-up parameters be reviewed prior to calibration or measurement to ensure
the selected measurement mode and values are correct.

mode using the key and press
Kinetics Set-up Menu
Measure Mode
Selects between transmittance or absorbance display on the kinetics graph Y-Axis.
Lag Time
The time in seconds that the instrument waits to commence taking run time readings after the user
starts a kinetics measurement. If the instrument is set to start on a level, then this time is ignored.
Run Time
The time period over which the instrument records and displays absorbance or transmittance. Results
taken during this period are used for the post measurement statistical calculations.
