  • Alternating voltage measurement with reduced input resistance (low impedance: 1 MΩ), 1 kHz/-3 dB low-pass filter can be activated


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.

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.

Measurement with current clamps and sensors

Current clamps and sensors are used for current measurements without interrupting the circuit under test and for high currents above 16 Amps. All E series multimeters offer convenient measurement with current clamps. The measured current value is automatically calculated for the user with the help of the adjustable clamp factor.

Fast Acoustic Continuity Test

Testing for short circuiting and interruption is possible with the selector switch in the position. The threshold value for acoustic signaling can be set to 1, 10, 20, 30, 40 or 90 W

Automatic Storage of Measured Values

The DATA function automatically saves the digitally displayed measured value after settling in. Acoustic signaling is also used to indicate whether the new measured value deviates from the initial reference value by less or more than 0.1% of the measuring range.

Storage of Min-Max Values

Comparable to the slave-pointer function of an analog instrument, the device saves the highest and lowest measured values after the MIN/MAX function has been activated or reset. These extreme values can be queried at the display.

Infrared Data Interface

The device can be remotely configured, and momentary and stored measurement data can be read out via the bidirectional infrared interface. The USB X-TRA interface adapter and METRAwin10 software are required (see accessories). Interface protocol and device driver software for LabVIEW ® (National Instruments™) are available upon request.

DAkkS Calibration Certificate

The multimeters are furnished with an internationally valid DAkkS calibration certificate (recognized by EA and ILAC). After the specified calibration interval has elapsed (recommended interval:
1 to 3 years, the multimeters can be inexpensively recalibrated in our own DAkkS calibration laboratory.
