Calibration Certificate included

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 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⏐X-TRA,

METRAHIT⏐O

UTDOOR, METRAHIT⏐TECH and METRAHIT⏐PRO instru-

ments 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 waveshape

independent RMS measurement (TRMS AC and AC+DC) for

voltage and current (METRAHIT⏐X-

TRA⏐OUTDOOR up to 20 kHz).

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.

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.
