1、Outline
WXYJ-100 wireless pressure drop and load tester wirelessly auto-complete phase three-wire or four-wire three-phase voltage transformer secondary voltage drop measurement is not required in the normal way to the distal end of the instrument to test the laying of a long test line voltage, thus avoiding unnecessary short circuit caused because the line is too long, and this is the voltage transformer should be avoided; but sometimes this voltage test leads need to cross the road, such as unattended dealings the vehicle will roll bad line, wireless secondary voltage drop tester effectively avoid such a situation. Automatic calculation of three-phase ratio error, phase error, integrated error.

3、Features
1)、High precision GPS time synchronization module test timing accuracy up 0.5uS, can effectively ensure accuracy angle difference.It can automatically detect and store data in a variety of measurement error caused by a wiring test leads, etc., and automatically corrected in subsequent tests.
2)、Specially designed software correction, the accuracy can be achieved without hardware adjustment correction in electricity Experimental research departments at all levels are field test.
3)、When in satellite signal shielding region, can be dedicated to the sync cable testing, this approach also has to ensure accuracy, reliability and safety, compared with other manufacturers of fiber mode, fiber-optic sync cable is very fragile, easily damaged, and I special cable company with the rugged toughness, and increasing reliability.
4)、With harmonic test function, you can always monitor harmonic pollution test users.
5)、With waveform display and vector analysis, can effectively detect wiring test metering device to prevent measurement errors caused by wrong wiring.
6)、Built-in high-capacity rechargeable battery pack, AC 220V outdoor no case may the instrument battery pack built fast automatic charger, fast charge the battery pack.
7)、The percentage of remaining battery power indicator, not a simple loss of power alarm.
8)、Large screen, high brightness LCD display, full Chinese menu and operation tips to achieve a friendly man-machine dialogue, touch buttons make operation easier, wide LCD with brightness adjustment, can be adapted to winter and summer seasons.
9)、The user can at any time test data via a mini printer will print out the results.
