Product Description
GF211B Multi-function Double Clamp Digital Phase Current-voltage
Meter Application Applicable to relay protection, electric power
measure, electric power construction and conversion engineering and
other professional, is the electric power department, factories and
mines, the petroleum chemical industry, the metallurgy system for
the secondary circuit check ideal electric meters. GF211B
multi-function double clamp digital phase current-voltage meter is
a multifunctional measurement, touch-tone phones operation, to
switch range, the measured data storage, keep, measuring array with
communication software, but through the instrument interface upload
data storage, and realize the large capacity can be output print
report or phase diagram of the double clamp digital phase
current-voltage meter. GF211B very suimeter for electricity
measurement, electricity check, electric power substation
maintenance, inspection and relay protection, differential
detection, start experiment field use. And for all the power
colleges as wiring discriminant training tools and teaching
equipment. GF211B multi-function double clamp digital phase
current-voltage meter is A full digital, many parameters
measurement instrument power frequency, instrument to apply
advanced computer technology, using the high performance A/D
converter to direct exchange sampling method is realized power
parameters measurement of frequency thanked the [voltage RMS (U1,
U2), current RMS (I1, I2), phase (Ø U1U2, Ø I1I2, Ø U1I1, Ø U2I2, Ø
U1I2, Ø U2I1), active power (P), reactive power (Q), work rate (F),
frequent power factor (PF)]. Instrument circuit structure is
simple, less parts, high reliability, built-in high-performance
lithium ion rechargeable batteries without external power supply
can work. Host, accessories of integration of the pormeter
packaging, easy to carry. Products in the power supply management,
inspection and measuring equipment maintenance of power is widely
used, is the electric power system measurement, biotech,
electricity each branch such as one of the necessary instruments.
Main Features The 65 X50 LCD display, high brightness backlighting,
show intuitional clear. Automatic detection range, direct
measurement and display true RMS voltage, current, voltage and
voltage, and that the voltage and current, current and all kinds of
current phase relationship, real-time measuring active power,
reactive power, frequency and power factor. Built-in rechargeable
lithium battery power instrument, shut off the backlight can work
continuously 18 hours, open when backlit can for eight hours or
more. Current plain amplitude and phase characteristics, can be in
5 mA-10 A range accurate measurement phase. Double channel,
symmetrical design, mutual insulation, safe, reliable, and can
detect the discriminant transformer of wiring group, the U-U phase
value, two voltage input circuit insulation isolation, won't cause
measured short circuit and burned instrument. With pointed mouth
clamp ampere current transformer, clamp the tip, high accuracy,
strong anti-jamming ability, in the line of dense applications
particularly convenient. Instrument built-in ten thousand clock
chip can accurately record test time, for reference. The built-in
memory, can save 60 group measurement data, but through the panel
direct function keys access has saved data set. With USB conversion
interface, will the meter measuring data group uploaded to the PC
and form to print report archive, also can be equipped with micro
printer site print directly output. The instrument is simple to
use, easy to operate very applicable to the electric power colleges
as wiring discriminant training tools and teaching equipment. Super
small streamlined structure, handheld, small volume, light weight.
