Use the keys at the bottom of the screen to select the digit
to be changed and use the keys adjacent to the
arrow
icons to increase or decrease the number. To change the
sign press the key below the
+ or - icon. Repeat presses
will cycle between + and –. Once the required absorbance
or % transmittance value has been entered press the key
adjacent to the
tick icon.
To change the maximum absorbance or % transmittance
value press the key adjacent to the maximum y-axis
value, this opens a number entry screen. Use the keys
adjacent to the
arrow icons to increase or decrease the
number. To change the sign press the key below the
+ or
- icon. Repeat presses will cycle between + and –. Once
the required absorbance or % transmittance has been
entered press the key adjacent to the
tick icon.
9.2.1.2 Setting Lag time or Start on Level
In this measurement mode starting the kinetics measurements can be delayed by setting a lag time or
a start on level. The lag time is the amount of time that the instrument will wait before starting the
kinetics measurements. The start on level is the absorbance level that must be reached before starting
the kinetics measurements. Both options can be set using the set lag time/start on menu. This function
is accessed by pressing the key below the
start time pause icon on the far left side of the x-axis. This
opens the lag time/start on level menu.
To set the lag time press the key adjacent to the
clock
icon. Use the keys at the bottom of the screen to select
the digit to be changed and the keys adjacent to the
arrow icons to increase or decrease the number. The lag
time can be reset to zero by pressing the key adjacent to
the
000 icon.
Once the required lag time has been entered in seconds
press the key adjacent to the
tick icon to save and return
to the settings menu.
To set the start on level press the key adjacent to the
Abs/%T icon. Use the keys at the bottom of the screen
to select the digit to be changed and the keys adjacent
to the
arrow icons to increase or decrease the number.
The positive sign can be changed to a negative sign by
pressing the key below the symbol
+ icon.
On the left hand side of the screen the symbol can be changed to read
greater than (>) or less than
(<) the absorbance level that has been entered. The start on level can also be
turned off (). Once
the required absorbance or % transmittance level (depending on the operating mode selected) has been
entered press the key adjacent to the
tick icon to save and return to the settings menu.
9.2.1.3 Selecting Absorbance or % transmittance
The operating mode is displayed on the left hand side of the screen. The default parameter is absorbance
and pressing the key adjacent to the
ABS icon cycles the operating mode between the absorbance or
% transmittance.
