AL 308 Secondary voltage drop and load tester
Implementation of standards:
JJG169-1993, JJG314-1994
Features:
1, the integrated secondary and secondary load pressure drop tester in one, user-site testing.
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, can transfer data with the computer on-line.
5, apparatus, instruments used lithium batteries as the power supply.
6, the instrument can measure ambient temperature and humidity.
Product parameters:
1, measurement 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.
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.
