iTest Pro ST007 - Correct Result; Fail Result; RCD in the Wiring Under Test; Maintenance

Note: The ST 007 should operate satisfactorily on
circuits protected by most 30mA or higher RCDs or
RCBOs. Factors which should be considered are where
equipment, such as computers may introduce Earth
leakage currents due to internal noise filter circuits. This
Earth leakage current can approach the trip threshold of
an RCD or RCBO, and the ST 007 test current will add to
it with the possibility of the protective device tripping.
Warning:
Before using the ST 007 on critical circuits which supply
computers, medical equipment, or other systems where
loss of supply is unacceptable, ensure these are not
being operated, in line with normal practice when using
electrical test equipment.
7. MAINTENANCE
7.1 Preserve long product life
For long maintenance of the product, pull out the ST 007
from the socket in the end of each test and do not keep
it plugged in the socket for long time.
6.3 RCD in the wiring under test
6.1
Correct result
the RCD will be tripped.
6.2 Fail result
the RCD will not be tripped.
