Applications
The multimeter is suitable for universal use in electrical
engineering, electrical installation, laboratory applications,
telecommunication, training etc.
The instrument can be used in the field and is equipped with
internal, mains-independent supply power.
Features
Three Connector Jacks with Automatic Blocking Sockets (ABS) *
All current ranges are implemented via a single connector jack
which prevents any possibility of operator error.
Beyond this, the automatic blocking sockets prevent incorrect
connection of the measurement cables, as well as selection of the
wrong measured quantity. Danger to the user, the instrument and
the device under test resulting from operator error is thus ruled
out.
* Patented (patent no. DE 40 27 801 C2 and US 5,166,599)
Overload Protection
The instrument is safeguarded for up to 1000 V in all measuring
functions by overload protection. Voltages of greater than 1000 V
and current of greater than 10 or 16 A are indicated acoustically.
Dangerous contact voltages are indicated when the 1 kHz low-
pass filter is activated.
The FUSE display appears at
instruments in order to indicate that the fuse for the current mea-
suring input has blown.

RMS Value with Distorted Waveshape
The utilized measuring method allows for waveshape
independent RMS measurement (TRMS AC and AC+DC) for
voltage and current
Activatable Filter for V AC Measurement
A 1 kHz low-pass filter can be activated if required, for example
when measuring motor voltage at electronic frequency
converters. The input signal is checked by a voltage comparator
for dangerous voltages as long as the low-pass filter is activated.
Measuring 5 V Square-Wave Signals with the
This function makes it possible to test circuits and transmission
cables by measuring the frequency and the keying ratio of pulses
with amplitudes of 2 to 5 V and frequencies of 100 Hz to 1 MHz.
Analog Scale for Quick Trend Display – Bar Graph or Pointer
The analog scale (with additional negative range for zero-
frequency quantities) allows for faster recognition of measured
value fluctuation than is possible with a digital display.
The instrument can be switched back and forth between bar
graph and pointer display.
Automatic or Manual Measuring Range Selection
Measured quantities are selected by means of a rotary switch and
a function key. The measuring range is automatically matched to
the measured values. The measuring range can also be selected
and fixed manually with a key.
