Functions and Advantages

Display Multiple Parameters Simultaneously

IT8600 provides 7 inch LCD display screen, easy user interface. Give full consideration to engineers' requirements in different tests, IT8600 not only can display multiple parameters simultaneously,but also has diversified display modes for choice, such as waveform, histogram and list etc.

Harmonic Measuring And Analysis Function

IT8600 provides powerful data measurement function, which can not only support measurement of conventional parameters such as Vrms, Vpk, Vdc, Irms, Ipk, Idc, W, VA, VAR, CF, PF and Freq, but also provide unique voltage harmonic analysis function to verify the harmonic interference of the object (UPS, generators, etc.) to be measured over the grid. The harmonic measurement function supports analysis up to the 50th voltage harmonic and it can display the percentage of each harmonic analysis results in different forms.

Functions and Advantages

Parallel/3-Phase Control

IT8600 provides parallel and 3-phase functions for three-phase and high-power applications. In 3-phase applications, users can make Y or connection according to their specific requirements. IT8600 is available for AC 380V input to meet diverse test requirements. ( *Only IT8615 and IT8615L are with this function)

Oscilloscope Function

The most unique highlight of IT8600 lies in the oscilloscope display function, which can display the input voltage and current waveform of the device under test
measured. Through the screenshot function key to save the current screen picture to peripheral storage disk by the front USB interface, easy for the second analysis.


I/V Monitor

IT8600 AC/DC electronic load is with I/V monitor and allow users to observe current and DUT output voltage through connecting to oscilloscope of BNC. The function is very useful for users to monitor the change of voltage and current by waveforms. Not only simplify the wiring, improve the measurement accuracy, but also save test cost without oscilloscope current probe
