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.
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 instrument in order to indicate that the
fuse for the current
measuring input has blown.
RMS Value with Distorted Waveshape
The utilized measuring method allows for wave shape independent
RMS measurement
(TRMS AC and AC+DC) for voltage and current up to 20 kHz.
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.
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.
