Features
1) PWM (Pulse width modulation) technology
2) Modular design allows customized configurations on hardware and
software, customer-friendly
3) Perform all tests like creep test, starting test, basic errors,
dial test, standard deviation and etc...
4) Measurement of voltage, current, power (active, reactive,
apparent), phase angle and frequency
with real time display of vector diagram
5) Harmonic test (2-21 times) and analysis & display of harmonic
6) Measure all types of single phase mechanical meters and
electronics meters, able to test
close-link meter, meters with RF communication module with protocol
provided by end user
7) Mode of tests: Fully-automatic, or manual operate by touch
screen
8) Error calculation reset buttons in each meter position; error
LED display timely.
9) QCD for quick connect the meters on the rack
10) Soft start/stop output
11) Black mark search & capture for the rotation disk
12) Testing various meters with different cosntant on positions
13) Test records memory for later continued calibration
14) Store test data, inquiry and print out and also can change
format of report
15) Dial test for various kinds of electric meters
16) RS232 or RS485 communication
17) PC software for operation
18) Support inputting barcode and self-definition, convinient for
test management
19) Auto short-circuit function if meter absence
Optional for dual current channels test (phase current, neutral
current) at same time/separately
