Functional check
Using accessories that are shipped with your probe and a source that supplies AC line voltage, perform the following procedure:
WARNING: T
o reduce risk of shock or fire, ensure that the accessories are fully mated before you connect to voltage sources
above 42 Vpk.
1. Connect the output of the probe to the oscilloscope input channel.
2. Connect the probe inputs to the AC voltage source.
3. Connect the inputs, set the voltage range, and perform the check as each row of the following table indicates.
