Gossen Metrawatt M240O OffersWith 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
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 (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.
Measuring 5 V square-wave signals
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 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. The infrared interface can be switched off in the standby mode.
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.
Infrared data interface
This multimeter can be remote configured, and momentary and stored measurement data can be read out via the bidirectional infrared interface. The USBX-TRA interface adapter and METRAwin 10 software are required to this end (sold separately).
