2.4.2 Memory Button - AEMC 3910 User Manual

The Model 3910 stores all the measurements present when peak is
selected. The first four measurements (V, A, W, PF) are displayed on page
1 and the following three measurements (Var, VA, Hz) on page 2 (press
the PAGE button). For example, you can find the voltage, the power, etc.,
at the moment when current is at a peak.
In PEAK mode, the typical acquisition time is 400ms. Each new peak is
taken into account as long as the PEAK button is activated. To exit PEAK
mode, press the PEAK button.
