2.BT02Voltagesensor 

The CMA BT02Voltage sensor is ageneric

probethatcanbeusedtomeasurevoltage

between‐10..10Volts.Ithastwobanana

(4‐mm)plugsforeasyconnection.

Note that this sensor has a direct

connection to the inputs of CLAB. The

sensor does not have differential

inputs,

and will not behave like a traditional

voltmeter.

To measure a potential difference between two points in a circuit, connect the

redandblackplugstothetwopoints.Apositivereadingmeanstheredplugisat

1.Practicalinformation

The black lead is connected to the common ground of the interface. Therefore,
