Adjustments

Offset Zero

Use this procedure to adjust the probe's offset zero.
NOTE. If your oscilloscope supports a probe calibration routine,
clear the probe calibration constants at this time.
If the offset zero is adjusted, perform a functional check of the offset
range before closing the compensation box.
1. Ground the probe tip by connecting the probe tip to the probe
ground socket.
2. Set the channel's vertical offset to 0.00 V.
3. Measure the displayed DC level.
4. Adjust Offset Zero for 0.00 ± 50 mV. (±5 mV when measured
directly without attenuation factor.)
