Basic operation

Probe offset

The probe offset is adjustable to permit operation within the linear range of the probe. To increase the sensitivity of the probe at
higher DC measurement voltages, you should adjust the offset for optimal probe performance.

Offset

NOTE.

See your oscilloscope manual for

speci

fi

c instructions on using the offset control.

1.

To set the probe offset, use the vertical
position control to set a zero reference
level on the oscilloscope display.
