with damp and damaged.
"Regulation" provides that continuously test for 3 to 5 times, each action
should be normal, each time interval should be not less than 30s. After test
logger should be set to zero.
3.Operation method
1. Let the output terminal of instrument connect to the two ends of arrester
counter (the connecting lead should be as short as possible), red terminal
connect to upper end, black terminal connect to earth terminal.
2. Well connect power cord (use DC power, need not connect power), then
check whether the equipment and wiring are correct, confirm all is ok, you
can start test.
3. Close power switch (power light glows), wait the voltage exceeds 600V,
you can start test (Rated voltage of instrument is 1600V; higher voltage can
also be customized according to user
’
s requirements).
4. Press
“
Test
”
key, output voltage will immediately drop, at this time you
can observe the action of counter.
5. For multiple tests, please wait output voltage exceeds 600V, then press
“
Test
”
key and observe the action of counter.
6. After test, please immediately turn off power supply; remove the wiring
after output voltage has completely come back to zero.
7. If you pressing
“
Test
”
key, output voltage do not drop, you should turn
off power supply, wait voltage come back to zero, then check whether there
is a breakpoint on the circuit or the type of discharge counter is not suitable
for the specified technical specification type.
