Information about the device

Device description

• The multimeter is a battery-powered, mobile hand-held measuring device with an extensive range of measurement possibilities. The true RMS measuring function allows for the precise measurement of sinusoidal and non-sinusoidal signals generated due to faults, e.g. by frequency inverters or switching power supplies of computers.
• The device is equipped with the following functional properties and equipment features:
• Automatic/manual range selection
• LCD display
• Can also be operated while wearing gloves
• Fold-out stand and holding fixture for measuring tips
• AC and DC voltage measurement
• Measurement of direct and alternating currents
• Resistance measurement
• Capacitance measurement
• Frequency/duty cycle measurement
• Diode testing function
• Acoustic continuity testing
• Hold function
• Calling the maximum and minimum value
• The integrated Bluetooth function makes it possible to connect the device to a terminal device via the Trotec MultiMeasure Mobile app.
• The measurement results can be displayed and saved on the terminal device either numerically or in form of a chart. Then, the measurement data can be sent in PDF or Excel format.
• The app also includes a report generation function, an organiser function, one for customer management and further analysis options. Moreover, it is possible to share measurements and project data with colleagues in another subsidiary. If MultiMeasure Studio Professional is installed on a PC, you can even use report templates and ready-made text blocks for various fields of application to turn the data into professional reports.

Overvoltage protection and measurement category

• The power grid is permanently subjected to short-time voltage peaks, the so-called voltage surge, which can be very low, for instance when a light switch is actuated, but also very high when a network operator switches over power lines. The height of the surge voltage depends on the position within a low-voltage network in which a device/machine is operated. The closer this position is to the supply line, the higher is the surge voltage to be expected. This means that an electricity meter of a house must be able to absorb a higher surge voltage than a Wlan router.
• For the purpose of simplification, the power grid is divided into four overvoltage categories. A rated surge voltage is assigned to overvoltage categories in each case, indicating the voltage peaks for which a device has to be designed:

printers, laboratory equipment, telephone system
CAT III| 4000 V| Devices without a plug:

e.g.: sub-distributions, cables, sockets, CNC machines, construction cranes, energy storage systems

CAT IV| 6000 V| Devices at the feed point:

e.g.: electricity meters, primary overcurrent protection devices, main switches

• In line with the overvoltage categories there are measurement categories defining the permissible scope of application of measurement and testing devices for electrical equipment and systems in low-voltage networks.
• The design of a measurement device determines in which environments and for which voltages it can be safely used. What is important in this connection for example is the touchability of live parts, anti-kink protection guards on the measuring lines or the insulation. Depending on the design details, the measurement device can carry out safe measurements up to a specific voltage in one or several overvoltage categories. The measurement category is specified on the measurement device as well as in the operating manual.
• The measurement category is indicated including the maximum voltage height, which can either be 300, 600 or 1000 Volt. The designation CAT III/1000 V for example means that the measurement device may be used in low-voltage indoor installation for voltages up to 1000 volts.
• Often several values are indicated on the device, for instance CAT III/ 1000 V and CAT IV/600 V. In these cases, different maximum voltages apply to the stated scopes of application. If no measurement category is specified, the measurement device is only considered as safe in measurement category CAT I.
• This measurement device is suited for category CAT III (600 V).
