AL422 Type electroscope manual
Implementation of standards:
GB776-76、IEC/IC78
It adopts capacity sensor technique，electron integrated digital circuit，Language and light display at the same time．The language is：“High voltage，be dangerous”，light adopts super brightness，and is not affected by sunshine，This product is with acute sense，stable performance， light volume，and convenient using．
1、the use of electroscope：
（1）Insulating pole shall be pulled tightly and firmly．press the self-detection button of signal indicator will speak out “High voltage，be dangerous”．
（2）According the figure fix the signal indicator
to the first section of insulating pole．
（3）Test the electroscope on electriferous conductor to see weather it is fine，during the operation，touch current conductor from far to near，then test it on cut-off equipment．
（4）Electroscope shall abide by（ DL408-91）regulation，test it once half a year．
（5）After long time using，when the sound
volume is decreased，can replace one 9V battery in the equipment．
