Applications
The instruments of the E- and high resolution series are extremely
rugged, reliable digital multimeters with housings made of impact
resistant ABS.
With a resolution of 60,000 counts and up to 26 different measur-
ing functions, they’ve been developed for professional use.
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. Auto-ranging is
available in all current measuring ranges.
Also the automatic blocking sockets prevent incorrect connection
of the measurement cables, as well as selection of the wrong
measured values. Danger to the user, the instrument and the
device under test resulting from operator error is eliminated.
* Patented (patent no. DE 10 2005 062 624)
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 METRAHIT E
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 a waveshape
independent RMS measurement (TRMS AC and AC+DC) for
voltage and current (METRAHIT E
Selectable Filter for V AC Measurement
A 1 kHz low-pass filter can be selected if required, for example to
measure the 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. A high-voltage symbol appears at the display if
dangerous voltage is present.
Measuring 5 V Square-Wave Signals with the METRAHIT E
This function allows to test circuits and transmission cables by
measuring the frequency and the duty cycle of pulses with ampli-
tudes 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 via the menu.
Automatic or Manual Measuring Range Selection
Measurement functions are selected by a rotary dial and a func-
tion key. The measurement range selection is done automatically
according to the input signal. Manual measurement range selec-
tion is possible via function key.
