Temperature Control
Cuvette Temperature [
o
C] is the reading of the cuvette air temperature sensor. Cuvette temperature
control (0-255) can be used to alter the current through the temperature controlling peltier element. The
direction of current flow and therefore whether there is cooling or heating is altered by the SET to
HEAT/COOL buttons. Used for testing cuvette temperature control.
Apply Lamp 1 LEDs
To check Lamp 1 or an LED light unit after entering values, click on the button to verify that they are
working properly. Lamp 2 only applies to the quartz halogen light source (smaller bulbs).
Batteries & Voltages
Board Voltage
Voltage available to CIRAS-2 board. This should be several hundred millivolts less than the battery
voltage.
Cuvette Voltage
Voltage of the external cuvette power source. When an Automatic type of leaf cuvette is connected, this
is the voltage measured on the PLC circuit board.
Left Battery Voltage
Refers to the current state of charge of the left battery. When fully charged, it should read > 13V.
