(1) Able to realize three-phase three-wire, three-phase four-wire and single-phase full-automatic measurement;
(2) It applies engineering plastic machine box, solid and durable, which effectively ensures safety of testing personnel and system;
(3) The instrument has the function of automatic range switching, which ensures testing accuracy;
(4) Electronic principle wire combined with DSP technology gains satisfying test stability and better interference resistance;
(5) Able to automatically calculate all the load-related parameters after measurement for customer analysis and test.
(6) It has a large-screen Chinese LCD display, and all the operations have the Chinese menu prompt; with functions of power failure storage and browsing of data, able to be connected with a computer for data transmission.
(7) Large-capacity 7.2V11Ah lithium battery for power supply, which causes no influence to testing circuit and avoids the necessity for system protection. Meanwhile, it shall be used when there is no power supply on site.
(8) Secondary load test adopts clamp ammeter for current sampling without the need to disconnect the secondary circuit. It can realize on-line measurement without power outage. Automatic range switching: During measurement, it can switch to different positions according to different testing values, which ensures measurement accuracy and display digit.
(9) The working time can last 24 hours (at most).
(10) Attached with portable charger, convenient to measure, and able to be externally connected to the charger for measurement.
(11) Small volume, light weight.
(12) It has extremely wide secondary working current/voltage range. Under 50mA working current, it is able to identify 1mΩ resistance and impedance and measure actual on-line load of S class current transformer with 5A secondary rated current; under 5V working voltage, and is able to identify 0.001mS conductance and electrical susceptance.
(13) Able to reserve 480 sets of measurement data which can be saved for ten years after power outage
(14) Large-screen display in Chinese, with RS-232 communication interface
