�DANGER!: identifies conditions and actions that most likely pose
hazard(s) or death.
�WARNING!: identifies conditions and actions that will pose hazard(s) or
death.
�CAUTION: identifies conditions and actions that will pose hazard(s) or
damage to the Tester.
�DANGER!
• Do not use the Tester around explosive environment. It may cause fire
and explosion.
• To avoid possible electric shock or personal inquiry, do not use the test
instrument or test leads if they appear to be damaged or if metal part is
exposed, or if test instrument is not operating properly.
• Do not touch the cables during testing.
�WARNING
• Do not open or disassemble the tester during testing.
• If the test instrument appear abnormal ( for example, no completed
display, incorrect calculation, housing damage, noise issue during the
measurement etc….), please contact our service department for repair.
• Do not use the tester if your hands are wet.
• Any test and measurement procedures in circuits equipped with residual
current devices should only be performed after having consulted the
operator terminals (data processing systems, material processing,
motors, etc.).
• The protective earth must be free of external voltage for the RCD test.
However if an extraneous voltage is present (>50V fault voltage),
the instrument only indicates Uf HI having been generated by the
measurement. The measurement interruption caused by excess of Uf
is only generated by the actual voltage present between the neutral
conductor (N) and the protective earth (E).
