Necessity of Phase Correction of the Probe When using the oscilloscope with a probe, the probe phase must be corrected by adjusting the variable capacitor inside the probe so that the gain is constant relative to the frequency. Measurements will not be accurate unless this adjustment is made, therefore you should make sure to perform this phase correction when using the probe for the first time. The input capacitance differs depending on the oscilloscope. It can also vary slightly from channel to channel, even on the same oscilloscope. Even if the phase has been previously corrected, you must perform the correction again if you move the probe to a new oscilloscope or a different channel.
