PKPK?
Obtains the stored value representing the difference between the maximum and minimum
signal values to be measured since the most-recent general reset, store reset or function
change.
Response Format
(Nr3) Max or Min:
The returned value represents the signal with two exceptions:
When an overload has occurred, and thus the maximum is not measurable, the
response is +200.000000E+33.
When no measurement has been made since a reset, the response is -
20.0000000E+36.
(Nr3) PkPk:
The returned value represents the difference between the max and min signals with
two exceptions:
When an overload occurs in one or both stores, the computation is still performed
and thus the response indicates a numeric difference which has an obviously
overlarge exponent.
When no measurement has been made since a reset, the response is -
40.00000000E+36.
Function Change, Power On and Reset:
These automatically clear Max, Min, and thus PkPk values.
Reset Max and Min Memories
MAX / MIN
Resets the specified store only.
PKPK
Resets both the MAX and MIN stores.
Function Change, Power On and Reset:
These automatically clear Max, Min, and thus PkPk values.
