1. SAFE TESTING
#
Electricity is dangerous and can cause injury and death. Always treat it with
the greatest of respect and care. If you are not quite sure how to proceed, stop
and take advice from a qualified person.
●
The symbol
#
on the instrument means that the user must refer to the
relevant section of this instruction manual for safe operation of the
instrument.
●
Pay particular attention to all WARNINGS and CAUTIONS in this instruction
manual.
WARNING indicates warnings to avoid electric shock and CAUTION indicates
cautions to avoid damage to the instrument.
1
．
This instrument must only be used by a competent and trained person and
operated in strict accordance with the instructions. KYORITSU will not
accept liability for any damage or injury caused by misuse or non-
compliance with the instructions or with the safety procedures.
2
．
It is essential to read and to understand the safety rules contained in the
instructions. They must always be observed when using the instrument.
3
．
This instrument is intended only for single phase operation at 230V AC
±
10% phase to earth or phase to neutral operation, and then only for loop
and RCD testing. For use in the continuity testing and insulation testing
modes this instrument
must be used ONLY on circuits which are de-
energised.
4
．
When conducting tests do not touch any exposed metalwork associated
with the installation. Such metalwork may become live for the duration of
the test.
5
．
Never open the instrument case
(except for fuse and battery replacement
and in this case disconnect all leads first) because dangerous voltages are
present. Only fully trained and competent electrical engineers should open
the case. If a fault develops, return the instrument to your distributor for
inspection and repair.
6
．
If the overheat symbol appears in the display ( ) disconnect the
instrument from the mains supply and allow to cool down.
7
．
For loop impedance tests to prevent unwanted tripping during loop testing
all residual current devices RCD'smust be taken out of the circuit and
temporarily replaced with a suitably rated MCB unit. The RCD must be
replaced after the loop test is completed.
