Displaying and saving minimum and maximum peak values
The peak values recorded (minimum and maximum) are saved in the in-
strument’s nonvolatile memory, and are available after any power failure.
You can reset the peak values by means of the corresponding RES com-
mand in the programming menu.
When you change the value of the CT the maximum and minimum alarm
threshold are automatically disabled.
