'''You should have received:'''
* A PhidgetTemperatureSensor 4 input
* A Mini-USB Cable
|
'''In order to test your new Phidget you will also need:'''
* Thermocouples with stripped end
||}}

===Connecting the Pieces===
{{UGbox|
# Connect the thermocouples to the terminal blocks on the 1048. Make sure that the thermocouple ground wire goes into the ground terminal. For example, if you are using a 3107 - Phidget K-type Thermocouple, the white wire is the ground wire.
# Connect the 1048 to your PC using the Mini-USB cable.

{{UGbox|
Double Click on the [[File:Ph.jpg|link=]] icon to activate the Phidget Control Panel and make sure that the Phidget Temperature Sensor 4-Input is properly attached  to your PC.

# Double Click on Phidget Temperature Sensor 4-input in the Phidget Control Panel to bring up TemperatureSensor-full and check that the box labelled Attached contains the word True.
# Select input 0
# Select the thermocouple type (we're using K-type in this example)
# Touch a source of heat (light bulb, candle or lighter flame) with the thermocouple probe and watch the Thermocouple temperature increase.
# The potential value will also increase as the thermocouple temperature increases.
# The ambient temperature gives you the board temperature.
# You can adjust the data sensitivity by moving the slider pointer.

==API==
{{UGapih}}

===Functions===

{{UGapi|int TemperatureInputCount () [get] : Constant
|Returns the number of thermocouples that can be read by the PhidgetTemperatureSensor.
}}

{{UGapi|double Temperature (int ProbeIndex) [get] : Celsius
|Returns the temperature of a thermocouple. This value is returned in degrees Celsius but can easily be converted into other units. This value will always be between TemperatureMin and TemperatureMax.  Please refer to the device specifications for noise and accuracy details.
}}

{{UGapi|double TemperatureMax (int ProbeIndex) [get] : Constant, Celsius
|Returns the maximum temperature that can be returned by a thermocouple input. This value depends on the thermocouple type.
}}

{{UGapi|double TemperatureMin (int ProbeIndex) [get] : Constant, Celsius
|Returns the minimum temperature that can be returned by a thermocouple input. This value depends on the thermocouple type.
}}

{{UGapi|double TemperatureChangeTrigger(int ProbeIndex) [get,set] : Celsius
|Sets the change trigger for an input. This is the amount by which the sensed temperature must change between TemperatureChangeEvents. By default this is set to 0.5. Setting TemperatureChangeTrigger to 0 will cause all temperature updates to fire events. This is helpful for applications that are implementing their own filtering.
}}

{{UGapi|double Potential (int ProbeIndex) [get] : Millivolts
|Returns the potential of a thermocouple input. This value is returned in millivolts, and will always be between getPotentialMin and getPotentialMax. This is the value that is internally used to calculate temperature in the library.
}}

{{UGapi|double PotentialMax (int ProbeIndex) [get] : Constant, Millivolts
|Returns the maximum voltage that can be measured by the 1048.
}}

{{UGapi|double PotentialMin (int ProbeIndex) [get] : Constant, Millivolts
|Returns the minimum voltage that can be measured by the 1048.
}}

{{UGapi|double AmbientTemperature () [get] : Celsius
|Returns the temperature of the 1048 board, measured near the thermocouple connector. This temperature is used as a reference for the thermocouple voltage.  This value will always be between getAmbientTemperatureMin and getAmbientTemperatureMax. 
}}

{{UGapi|double AmbientTemperatureMax () [get] : Constant, Celsius
|Returns the maximum temperature that can be returned by the ambient sensor.
}}

{{UGapi|double AmbientTemperatureMin () [get] : Constant, Celsius
|Returns the minimum temperature that can be returned by the ambient sensor.
}}

{{UGapi|int ThermocoupleType(int ProbeIndex) [get,set]
|Returns/sets the thermocouple type for an input. The possible values are J, K, E, and T, corresponding to K, E, J and T-Type Thermocouples.  Support for other thermocouple types, and voltage sources other than thermocouples in the valid range (between getPotentialMin and getPotentialMax) can be achieved using getPotential.

:Note that this function will vary widely between APIs.  Please refer to the Manual for the API you are programming against for exact calling conventions.
}}
===Events===

{{UGapi|OnTemperatureChange(int ProbeIndex, double Temperature) [event]
|Event that fires whenever the temperature changes by more than the TemperatureChangeTrigger.
}}

{{UGapi|OnError(int code, String description) [event]
|PhidgetTemperatureSensor returns EEPHIDGET_OUTOFRANGE when an input goes out of the range specified by PotentialMin-PotentialMax or TemperatureMin-TemperatureMax. The event is reported once per input per out-of-range type, until the value has gone back into range. The description specifies the input, the type of out-of-range error and the out of range value that was read. This should only happen for inputs which don't have a thermocouple attached.
