¡ñ 0.1%portable
single-phase electric source integrative function
¡¡ Voltage is 220V, with
largest current 10A. It is possible to input different
current and
angles.To chose different checking points by using
¡¾0¡¿keying to check single-phase device.
This device also can set checking point unit that
makes this device calibrate itself autom-
atically and save and print checking results.
¡ñ Single-phase field use checking function
¡¡ When it is used as a
field testing device, it is a high-accuracy field
use checking dev-
ice (¡À0.1%).But there are essential differences
between this device and single-phase field
use checking device with electric meter chip. Through
16 bit A/D and high-speed 32 bit DSP
processor, it samples signals of voltage and current
and calculates electric parameter. Me-
anwhile, its current output function can be used
as analog virtual load, largely convenient
for filed measure of single-phase watt-hour meter.
¡ñ Transformer¡¯s self-calibration function
¡¡ This device utilizes
our company¡¯s patent technology, automatically measuring
transfor-
mer¡¯s error and calibrating it, with the purpose
to guarantee the constant stability of t-
ransformer¡¯s error.
¡ñ Waveform showing function: directly
display U, I waveform;
¡ñ Harmonic testing function: show
all data of 2nd ~25th harmonic waveform in forms
of
histogram;
¡ñ Save and query function: able
to save 1000 pieces of checking records. Able to
inqu-
ire in different ways, including fuzzy query;
¡ñ Distant upgrade function: through
download updating package, able to upgrade the so-
ftware system of HA and enjoy new function and characteristics
of HA constantly;
¡ñ Bilingual-language function:
able to read both Chinese and English in the screen;
¡ñ Help function: when press ¡¾F1¡¿,
help interface will pop out;
¡ñ Multi-ways of electricity supply: three
ways to supply electric energy, using batt-
ery, electricity input online or external. |
