overview
model td3100, a high-precision single-phase reference multimeter, can simultaneously measure multiple electrical parameters in an ac circuit, such as voltage, current, frequency, phase, harmonic, active power/electric energy, reactive power/electric energy, apparent power, power factor, etc.
the optional accuracy classes of voltage or current are 0.01, 0.02 and 0.05, the corresponding optional accuracy classes of power and electric energy are 0.02, 0.05 and 0.1.
applied to calibrate ac standard source, and can be used as a reference meter for ac electric energy metering.
applications (class 0.02)
● calibrate single-phase ac voltage or ac current standard sources (class 0.05 and below)
● calibrate single-phase ac active power sources (class 0.1 and below)
● calibrate single-phase ac electric energy meters (class 0.1 and below)
functions
● electrical parameter measurement: the ac voltage is from 12 v to 792 v, the ac current is from 2 ma to 120 a, automatic or manual switching on all ranges.
● waveform display: oscilloscope function can display the waveform of the measured electrical parameters in real time.
● harmonic analysis: measure 2nd to 64th harmonic, analyze harmonic content and total harmonic distortion, and draw harmonic histogram.
● phase measurement: measure phase difference between voltage and current, and intuitively display by phasor diagram.
● energy metering: standard energy pulse i/o function can be used as a standard for single-phase ac energy metering.
● other function: stability test, trend curve display, data statistics and analysis, etc.
features
● a wide range of ac currents can be measured by connecting each phase current input just with a pair of terminals.
● no shifting on the primary side of the transformers, it will not cause damage or change the measurement accuracy no matter which range suddenly enters a large current.
● high reliability, the switch will not damage the instrument in a limit state (e.g. 500 v, 100a), but can also ensure the value accurate.
● good electrical isolation and protection between ac voltage and ac current measurement loop.
● large lcd touch screen, more intuitive of value display and easier operation.
● easy to build automatic detection system with the built-in rs-232 interface.
