Informationen
The PHILIPS Digital multimeter PM 2421 is a universal
instrument with digital display for the accurate measurement
of electrical quantities.
The instrument permits of measuring direct and alternating
voltages in a level range of more than 1:10 . The frequency
range in the case of alternating voltage measurements
extends form 10 Hz to 1 MHz.
In conjunction with a measuring probe (optional) it is
possible to carry out HF voltage measurements at frequencies
up to 700 MHz.The PHILIPS Digital multimeter PM 2421 is a

In conjunction with a measuring probe (optional) it is
possible to carry out HF voltage measurements at frequencies
up to 700 MHz.
Current and resistance measurements are possible with the PM
2421 in a range greater than 1:10^.
Range and mode selection is effected with the aid of simple
and conveniently arranged push-buttons. An automatically
controlled measuring range selector switches a voltage
divider within 3 decades so that the most favourable display
value is obtained. If desired, the range selector can also
be operated manually.
The measuring data (polarity of the direct voltage,
automatically selected range and the digital measuring
quantity) are available from the memory in encoded digital form.
With the aid of an additional printed circuit board which
can be plugged into the digital section, the digital
information is converted into standard levels, thus enabling
the connection of a printer or recorder.
Apart from the digital output signal a conventional analogue
output signal is also available for continuous recording of
the measuring quantity.
The circuit zero is isolated from the housing and from the
mains by means of a double screening so that floating
measurements are also possible.
The instrument is provided with integrated circuits and
silicon semiconductors.
On account of its high sensitivity, its great accuracy and
its rugged construction, the PM 2421 is suitable for
research and development as well as for educational
purposes, repair service, testing, general industrial
applications etc.
