Frequency measurements
Caution!
Before attachment of the measurement leads, the object being tested must
be de-energised, so as not to damage the device or the object being tested. In
cases of doubt, the freedom from energy must be proved by measurement.
• Place the function switch
.
• Insert the measuring leads

and
.
• Connect the measuring prods with the object being tested and apply the
voltage. Thereby, the maximum measurable voltage amounts to 10 V.
The frequency in kilohertz (kHz) or megahertz (MHz) can now be read
off in the display
• You can also call up the frequency measurement, in that you implement
the voltage measurement and then press the button
indicator Hz appears in the display
Impulse range measurement
With this function you can measure how long (duration in %) a signal within
a given period is low resp. high. The measured signal type must be periodic
(repeating itself in the same pattern in the same time intervals).
