oscilloscope only, and Probes attenuation set as 10X. Only if the oscilloscope
fulfills the following two conditions at first, these specification standards can be
reached.
 This instrument should run for at least 30 minutes continuously under the
specified operating temperature.
 If change of the operating temperature is up to or exceeds 5 ℃ , do a
"Self-calibration" procedure (see "How to Implement Self-calibration" on
P13).
All specification standards can be fulfilled, except one(s) marked with the word
"Typical".
