as Standard Feature

Applications

Instruments included in the so-called E and high-resolution series are

extremely rugged, reliable digital multimeters with housings made of

impact resistant ABS. With a resolution of 310,000 digits and roughly

30 different

measuring functions, they’ve been developed for profes-

sional use.

Features

RMS Value with Distorted Waveform

The utilized measuring method allows for waveform independent

RMS measurement (TRMS AC and AC+DC) for voltage (up to

100 kHz) and current (up to 10 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 convert-

ers. The input signal is checked by a voltage comparator for dan-

gerous voltages as long as the low-pass filter is activated. A high-

voltage symbol appears at the display if dangerous voltage

(> 45 V) is present.

Automatic / 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 locked manually with a key.

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.

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, US 7,439,725)

Overload Protection

Overload protection safeguards the instrument in all measuring

functions for up to 600 V. Voltages of greater than 600 V and cur-

rents of greater than 10 or 16 A are indicated acoustically.

Dangerous contact voltages are indicated when the 1 kHz low-

pass filter has been activated.

FUSE appears at the display if the fuse for the current measuring

input blows. Switching between high and low impedance mea-

suring functions is disabled in the vent of dangerous contact volt-

age.

Measurement with Current Clamp Transformers and Sensors

Current clamp transformer and sensors are used for current mea-

surements without interrupting the circuit under test, and for high

amperages (> 16 A). The measured current value is automatically

calculated and displayed for the user with the help of the adjust-

able clamp factor.
