8.3.1 Automatic 8 cell turret
When the automatic 8 cell turret is in use the 8 cell turret
icon is displayed in the bottom right hand corner of the
screen. The current cell position is displayed adjacent to
the 8 cell turret icon. The 0 position should always be used
for the zero calibration sample.
To perform measurements using the automatic 8 cell turret, insert the cuvettes containing the samples
into turret positions 1 to 7. Insert the cuvette containing the blank solution into turret position 0. Enter
the required measurement mode and set up the required measurement parameters. Press the key below
the
calibrate to zero icon. The instrument will automatically move the turret around to position zero to
perform the measurement. Once the calibration is complete the measure sample icon will appear and
the turret will return to its original starting position.
Press the key below the 8 cell turret icon to highlight
the icon and the two arrow icons above. Press the keys
adjacent to the
arrow icons to increase or decrease
the current cell position of the turret, until the required
sample position has been selected. Press the key below
the
measure sample icon. The instrument will perform a
reading and display the result on the screen.
To measure the next sample select the next turret position and press the key below the measure sample
icon. Repeat this process until all the samples have been measured. To adjust the wavelength press the
key below the
8 cell turret icon and use the arrow icons to adjust the wavelength.
8.3.2 Peltier

the bottom right hand corner of the screen. The current
temperature is displayed above the set point temperature
adjacent to the peltier icon. Below the peltier icon there
is an arrow icon to indicate if the current temperature is
below or above the set temperature. To adjust the set
point temperature hold the key below the
peltier icon
for 2 seconds.
This opens the peltier settings screen. 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. The temperature can be set in °C
or °F by pressing the key adjacent to the
°C icon. Repeat
presses will cycle between °C and °F.
Once the required temperature has been selected press
