Peak - Magnet-physik EF 14 Operating Instructions Manual

Electronic Fluxmeter EF 14
Fig. 4.2.2: Display of maximum, minimum and difference
Pressing Reset sets the readings back to zero.
Maximum and minimum are captured with the measuring rate of the EF 14. The Max./Min.
function is therefore used to capture exactly the extremes of normal, slowly changing magnetic
flux. For the measurement of fast changing pulses, the Peak function must be used instead.
If the Max./Min. key is once more pressed, the display of maximum, minimum, and difference
is switched off.

4.3 Peak

The peak values of fast changing pulses can be measured using the Peak function. This
function shows the highest positive and the lowest negative value since Reset has been pressed
the last time.
In DC mode the reading with the largest absolute value is shown, independently of the sign (+
or -) in large numbers in the center of the display. In the line below the absolutely highest value
with opposite sign is shown. This value is usually called valley.

In AC mode the Peak function shows the peak value of the flux waveform and not the peak
value of the RMS.
Pressing Reset sets all values back to zero.
Main application of the Peak function is the measurement of the maxima of magnetizing
pulses, see chapter 5.2.
