Applications

The multimeter is suitable for universal use in electrical 

engineering, electrical installation, labor

atory 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. EP 1801 598, US 7,439,725)

Overload Protection

The instrument is safeguarded for up to 1000 V in all measuring

fun

ctions 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 indicat

ed when the 1 kHz low-

pass filter is activated. 

The FUSE display appears at METRA HIT AM XTRA / X-TRA / OUTDOOR,

METRA HIT AM TECH / T

ECH and METRA HIT AM PRO / PRO instruments

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 (METRA HIT AM XTRA / X-

TRA / OUTDOOR up to

20 kHz).

Activatable Filter for V AC Measurement

A 1 kHz low-pass filter can be activat

ed if required, for example

when measuring motor voltage at electronic frequency 

converters. The input signal is ch

ecked by a voltage comparator

for dangerous voltages as long as the low-pass filter is activated.

Measuring 5 V Square-Wave Signals with the

X-

TRA

UTDOOR

This function makes it possible to test circuits and transmission

cables by measuring the frequency and the duty cycle 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 fast

er recognition of measured

value fluctuation than is possible with a digital display.

The instrument can be switched back and for

th between bar

graph and pointer display.
