	When measuring voltage levels below 5V, you'll have more accuracy if you connect the leads directly to the [[Analog Input Primer\|analog input]] of an interface kit.		When measuring voltage levels below 5V, you'll have more accuracy if you connect the leads directly to the [[Analog Input Primer\|analog input]] of an interface kit.

	Since the 1135 Voltage Sensor can measure a differential voltage, the common mode rejection (CMR) is an important specification. CMR refers to the amount of voltage that both input terminals of an differential amplifier can be offset without affecting the output gain. For example, if the positive terminal sees a voltage of 7V and the negative terminal sees a voltage of 5V, then the CMR would be 5V and would output a value of 2V at unity gain. For the 1135 Voltage Sensor, it is able to measure the differential voltage of +/-10V with a CMR of 40V while keeping the accuracy within 2%. Please note that the error specifications do not include the error introduced by the Analog to Digital Conversion on the Analog Input. (if you are using the 1135 with a PhidgetInterfaceKit) The majority of error introduced by the Analog to Digital conversion is from the error in the voltage reference (0.5% max), and the limitation of resolution in the SensorValue property.

	~~===Coding for your Sensor===~~
	Phidget analog sensors do not have their own API, but instead their output is a voltage that is typically converted to a digital value and accessed through the SensorValue properties and events on a Phidget InterfaceKit. It is not possible to programmatically identify which sensor is attached to the Analog Input. Your application will need to apply the formula from this manual to the SensorValue to translate it into usable data. Please see the Phidget InterfaceKit product manual for code samples, an overview of its API, and a description of our architecture.
