(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
