Probe Offset Adjustment

NOTE
Keysight N2818/9A Differential Probes User Guide
The N2818A/19A differential probes can be adjusted for zeroing out the
probe's offset voltage using the trimmer tool supplied with the probe.
Follow the procedure described below to perform the offset zero
calibration.
Allow the oscilloscope and probe to warm up for 20 minutes before
performing the adjustment.
1 Connect the probe to an oscilloscope channel input. Turn on the
oscilloscope and wait for 20 minutes to allow the oscilloscope and
probe to warm up.
2 If the oscilloscope needs calibration, perform a user calibration before
the probe calibration.
3 Using the probe's connection accessories, short the + and - inputs
together.
4 Press Default setup and Autoscale of the oscilloscope.
5 Press the channel button for the probe and set the oscilloscope
channel to DC coupled mode.
6 Set the oscilloscope to Averaging mode (x8 or higher) to reduce
oscilloscope noise, if needed.
7 Set the vertical scale of the oscilloscope to 100 mV/div.
8 Using the offset adjustment tool that comes with the probe, adjust the
probe offset voltage to zero volts.
