9.2.4 Digital signal output
Frequencies
For frequencies and pulses socket P3 is pro-
vided. In submenu P3 the following can be se-
lected : 4
frequency ranges
1 to 4000 Hz,
1 to 10.00 kHz
1 to 40.0 kHz
1 to
100 kHz
Within these ranges the pulse width and the
pulse / pause ratio can be set in %.
pulse width:
50.0 %
Pulses
There are also two
pulse ranges
for which the
period duration
is specified :
2 µs to 99.999 ms
2 ms to 99.999 s
The
pulse duration
can also be set here.
Pulse duration: 01.000 ms
Pulse variables, an overview
For a clear and easy-to-understand overview of
these variables (frequency, pulse width, pulse
duration, pause duration) there is a further sub-
menu; this can be accessed by pressing the
►
F
key again.

9.2.5 Continuity check
The test cable connected at socket P4 provides
a continuity check. The threshold above which
continuity is reported (by visual and acoustic
signals) can be set between 1 and 1000 mV.
The displayed measured value indicates the
voltage drop, e.g. the voltage flowing through a
diode.
