The Voltage sensor BT32i is designed for measuring voltages between -500 and +500 mV. The sensor has diff erential inputs; measurements can be done directly across circuit elements without the constraints of common grounding. It has two 4-mm plugs for easy connection.

Range: -500 ... +500 mV
Resolution (12-bit): 338 μV

Can be used to:
• measure small voltages in AC and DC circuits,
• record characteristics of a light bulb or a diode,
• measure voltages in series and parallel electrical circuits.
