About Gossen Metrawatt M240A TRMS System Multimeter

TRMS System Multimeter with Infrared Interface, +-12,000 DigitsOur new STARLINE generation instruments, including METRAHIT BASE, PRO and X-TRA, are rugged, reliable digital multimeters with housings made of impact-resistant plastic. They feature a new design and are equipped with state-of-the-art technology.ApplicationsThe multimeter is suitable for universal use in electricalengineering, electrical installation, laboratory applications,telecommunication, training etc.The instrument can be used in the field and is equipped withinternal, mains-independent supply power.Features in detailThree Connector Jacks with Automatic Blocking Sockets (ABS)((Patented (patent no. DE 10 2005 062 624, US 7,439,725))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 ProtectionThe instrument 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.RMS Value with Distorted WaveshapeThe 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 MeasurementA 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 with the METRAHITThis function makes it possible to test circuits and tran
