Property reference

	Properties
	Themistor
	Ohms Value at 25C
Thermistor resistance at 25C is usually found on the thermistor datasheet. If you have a 10K thermistor, that that will be the value at 25C
	Beta Value
Beta value is usually found on the thermistor datasheet
	Fixed Resistor
	Ohms Value
Value of pullup or pulldown fixed resistor in ohms
	Resistor Biasing
Pullup - Fixed resistor is connected to + of the supply Pulldown - Fixed resistor is connected to 0V of the supply
	ADC
	Channel
Analogue Input Channel - Which pin is the analogue input connected to?
	VRef voltage
Used by the GetVoltage or GetString component macros to take an ADC reading and convert it into a Voltage. +VRef voltage x 10mV Default 500 = 5.0V
	VRef option
Defines what is used as the ADC maximum reference. ADC Range = GND to VRef Voltage VDD - Defines the microcontrollers power supply pin as the max reference, VREF+ Pin - Dedicated pin on the microcontroller to allow for a variable reference voltage.
	Conversion speed
Clock setting to select how fast the ADC peripheral will perform an ADC conversion. The FRC setting is based on a RC time base and so will vary with temperature and pressure. Other settings are generally based on divisions of the master clock.
	Acquisition cycles
Number of micro seconds to wait for the ADC input to charge before starting the analogue sample.
	Bit Depth
Maximum number of digital bits the ADC can sample. 8 bit = ADC range 0 - 255 10 bit = ADC range 0 - 1023 12 bit = ADC range 0 - 4095
	Temperature
	Offset x 100
+/- x100 Enter temperature offset x 100 For example, temperature measured with an accurate thermometer is 22.0. Returned is 23.4, which is 1.4 degrees too high. For offset enter -140.
	OffSet

	Result Decimal Places
Number of decimal places (0 to 4) for temperaure results
	Simulation
	Highest Temperature

	Lowest Temperature

	Temperature Units
