the test process,we must pay attention to this terminal can’t fall off,if it fall off,the test object will
full of high pressure,that it may cause the occurrence of electric shock accident.
7
DC high voltage output port:The DC high pressure output port of test instrument will have
high voltage output when in the test,please don’t touch the high pressure port,the high voltage
output line, the high pressure probe alligator clip and the measured object.After the test is
finished,please confirm that the whole circuit is discharged completely then can replace the test
object.
8
AC high voltage output port:The AC high pressure output port of test instrument will have
high voltage output when in the test,please don’t touch the high pressure port,the high voltage
output line, the high pressure probe alligator clip and the measured object.
9
Power detection indicator lamp,"power supply grounding,safety"lamp:Connecting the
instrument and the power line use by city electric,the power switch of the tester is placed in the OFF
state;if the connection of N,L,G in city electric is correct,the power ground safety indicator lamp
will light;if the connection of N,L,G is wrong,then the green lamp doesn’t light,please check the
power supply.
10
High voltage output indicator lamp:This lamp is out of control of the electric circuit.If the
voltage in the high voltage output port is greater than 110V,this lamp will flash.If in the reset
state,the lamp will flash,then the high voltage output port may have high output,it is prohibited to
touch any part of the test circuit.
11
Super leakage indicator lamp This lamp is on when the test is not qualified.

Time display window:The range of time is 0.0s~999s.When the time is less than 100s,the
time resolution is 0.1s;when the time is greater than or equal to 100s,the time resolution is 1s.If the
time is set to 0.0s,then the test time to add count;when the time is not set to 0,the time to reduce
count.
