Gossen Metrawatt M242A Offers

With its wide range of functions, this advanced multimeter is an ideal tool for many tasks and areas of work. Additionally, the ergonomic design ensures maximum ease of use and safety.

Features

  • TRMS measurement up to 10 kHz with digital display (12,000 digits) and analog scale
  • Measurement of voltage and current, DC, AC and AC/DC, resistance, temperature, frequency, continuity/diodes
  • Automatic measuring range selection and measured value storage
  • Voltage measurement with a basic accuracy­ of ±0.05% (V DC)
  • Automatic storage of measured values: DATA/MIN/MAX
  • Large, light-blue illuminated display with extra-large characters (0.6" [15 mm]) and an analog bar graph for dynamic processes
  • Separate battery and fuse compartments
  • IP52 protection against dust and water
  • Safety for the user and the instrument in measuring categories CAT IV up to 600 V and CAT III up to 1000 V

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.

Overload protection

It 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 lowpass filter is activated. The FUSE display appears 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.

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.

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. It can be switched back and forth between bar graph and pointer display.

Automatic or 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 fixed manually with a key.

Fast acoustic continuity test

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

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 minimum/maximum values

Comparable to the slave-pointer function of an analog instrument, this multimeter 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.

Battery charging status - power saving circuit

The battery charging status is indicated by means of four symbols. This multimeter is switched off automatically if the measured value remains unchanged for a period of between 10 and 59 minutes (adjustable), and if none of the controls are activated during this time. Automatic shutdown can be deactivated by switching it to continuous operation.

Protective cover for harsh conditions

This multimeter is protected against damage in the event of impacts or dropping by means of a soft rubber cover with tilt stand and test probe holder. The rubber material also assures that it does not wander if it is set up on a vibrating surface.
