Other Considerations
Component heating caused by changes in ambient tempe rature or
high voltage will cause a slight change in calibration accuracy.
With high-frequency signa ls, such as fast transients, ringing ma y
occur which will distort the actual waveform . This ringing is due to
resonance occurring between t he capacitance of t he probe and the
ground lead inductance.
Problems Encountered Using the Probe
If you experience probl ems making me asurements with the probe,
consider the following remedies:
H Check low frequency compensation and adjust as nec essary.
H If you have the probe connected to an oscilloscope, check the
front panel controls of the oscilloscope to verify that the signal is
displayed properly.
H Use a ground lead.
H Don’t use ground leads tha t are t oo long (causing ringing).
H Because of probe characteristics, small differences in i nput
capacitance between oscilloscopes and scope channels can affect
the voltage measurement. The probe com pensation should be
checked each time the probe is connected to a different input
channel or to a different oscilloscope.
