AL307 Secondary voltage drop tester
Implementation of standards
JJG169-1993, JJG314-1994
1, three-phase three-wire, three-phase four-wire, single phase and fully automatic measurement of zero means.
Features:
2, the measurement is completed, automatic calculation of composite error and drop error.
3, the complete elimination of lead, isolation mutual inductor and Interference caused the error.
4, data storage and browsing capabilities with power-down, online delivery of data with the computer.
5, can be equipped with more than 200m pay-off vehicles used in tandem to facilitate the long-distance use.
Product parameters:
1, range: ratio error: 0.001% ~ 19.99%, angle difference: 0.01 '~ 599';.
2, Resolution: ratio error: 0.001%, angle difference: 0.01 '.
3, the basic error: DX = ± (1% × X +1% × Y ± 2 counts).
DY = ± (1% × X +1% × Y ± 2 counts).
two words: quantization error of the instrument.
4, the voltage meter accuracy: 0.5%.
5, scope of work: Voltage 50 ~ 120V.
6, direct action values: worse than the angle difference greater than 20% or greater than 600 ', voltage <2.0V;.
7, the environmental conditions: temperature of -5 ° C ~ 40 ° C, relative humidity "95%, Altitude <2500m.
