Specification

Features of the device

• Fast and easy reading is provided by a colour display with a counting range of up to 50,000 digits, a resolution of 320×240 pixels and a diagonal of 3.5 “. Additionally, the display allows reading at a wide angle also in poor lighting conditions;
• over 14 measurement functions, including AC / DC voltage measurement, AC / DC current measurement, resistance, capacity, temperature, pulse width, fill factor, frequency
• The AC + DC function allows you to simultaneously display the value of the constant and variable component or the sum of both components during voltage measurement
• The 4~20mA function used for, among others, measurement of the control circuits of temperature, pressure, pH or flow sensors.
• True RMS for AC voltage and current allows to measure the effective value of distorted waveforms;
• Built-in low-pass filter, thanks to which the voltage measurements will be more accurate by eliminating the influence of interference generated by machines and electronic devices;
• saving the results of fast 1ms waveforms thanks to the PEAK value measurement function
• the relative REL measurement function allows, among others, elimination of resistance values of test leads
• Displaying simultaneously the result of the measurement of the constant and alternating component of the signal for quick reading of two results at the same time;
• real-time clock that allows adding date and time of measurement to each sample
• Recalling measurement results from the built-in memory for 2000 measurements with recording of the name and date of measurement;
• possibility of quick  detection of irregularities due to the registration of measurement results in graphical form of the trend, thanks to the Trend Capture function and the built-in recorder with the possibility of recording up to 10.000 samples;
• Registration of maximum and minimum values and calculation of the average of current measurements
• Built-in Bluetooth module for sending live measurement results to Android mobile devices
• HELP function to quickly explain the meaning of a given measuring function and buttons
• Optional strap with a hook allows easy operation with both hands;
• Protection against water flooding and penetration of dust into the electronic system due to its extremely robust housing with IP67 protection level;
• The rotary switch has been designed for easy handling even when working in thick gloves in dangerous and difficult conditions;
• Dedicated lithium-polymer battery allowing long-term operation of the device;
• A dedicated charger and power supply for charging the battery without removing it.
