Changing the control mode is done through the menu by changing the Mode
parameter to T Mode, R Mode, or Ite Mode.
Constant temperature mode uses the sensor constants to calculate the
resistance of the thermistor at the desired or actual temperature.
While most users will only need the temperature control mode, the constant
resistance mode allows you to bypass the sensor equation and directly select
the sensor set point. This can be useful when only the desired sensor value is
known, or when the sensor-to-temperature conversion values are not available
for your sensor.
Main Display Screen
The top of the main display will be the temperature of the active sensor, except
when adjusting the set point. The bottom half of the display can display one of
three sets of data:
1. Set point and TEC current and voltage
2. Sensor readings for the non-active primary sensors
3. Sensor readings for the auxiliary sensors
4. Digital input and output status
Example displays are shown below:
Main Display: Set Point and TEC Current and Voltage
Main Display: Additional Primary Sensors
T=25.000°c
Sens 2= 25.000°c
Sens 3= Disabled
T=25.000°c
TSET= 25.000°c
I= 3.25A V= 6.72V
