3.6. PEAK function (1 ms)
This function enables 1 ms voltage or current PEAK signals to
be captured.
Before a signal is captured, the clamp must first be calibrated
by holding the PEAK button down for more than 2 seconds,
until "CAL" is displayed, indicating that the offset has been
correctly taken into account.
Choose the positive or negative sign of the peak (P+ or P-)
with short presses on the PEAK button.
To quit the manual range, you must hold the RANGE (MX 650)
or the / (MX 655) button down for at least 2 seconds; the
clamp then returns to normal mode.
3.7. MAX MIN function (500 ms)
To activate the MAX MIN function, press on the MAX MIN
button. The MAX value is then displayed.
If you press on the button again, the MIN value will be
displayed.
If you press on the button a third time, the instantaneous
measurement is displayed (however, the "MAX MIN" symbol
flashes, indicating that the function is still active).
To quit the manual range, you must hold the MAX MIN button
down for at least 2 seconds; the clamp then returns to normal
mode.
