Note:
– Use the "Hz%" button (11) to switch the display to frequency (Hz) and pulse length (%)� Each press switches
the function� Autorange is deactivated� This enables monitoring of possible ripple signal (superimposed fre-
quency)� In case of pure direct current, the frequency and % displays are "zero"� Without a measured signal,
phantom values may be displayed� They disappear when a direct current is measured�
