	The 1135 measures the differential voltage between the input terminals and outputs the difference proportionally. The maximum differential voltage that can be measured accurately is ±30V. When the positive and negative inputs are equal, the voltage output value is 2.5V. When the positive input is 30V greater than the negative input, the voltage output is 4.5V and when the positive input is 30V less than the negative input, the voltage output is 0.5V.

	When measuring voltage levels below 5V, you'll have more accuracy if you connect the leads directly to the [[Phidgets_Connectors\|voltage input]] of the HUB0000 (or [{{~~SERVER~~}}~~/?view=comparetable&rel=Analog%20Inputs compatible product]~~).

	Since the 1135 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 a 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, 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.

			::<math>V_{diff} = \frac{V_sens - 2.5}{0.0681}</math>

	where V<sub>diff</sub> is defined as V<sub>positive</sub> - V<sub>negative</sub>.		where V<sub>diff</sub> is defined as V<sub>positive</sub> - V<sub>negative</sub>, and V<sub>sens</sub> is the voltage returned by the 1135.
