1 Safe Testing
1
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.
1 This instrument must only be used by a competent and trained person
and operated in strict accordance with the instructions. Kewtech 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%-15% phase to earth or phase to neutral operation, and then
only for loop, prospective short circuit current (PSC) 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 Kewtech 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 (RCDs) must 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.
8 If abnormal conditions of any sort are noted (such as a faulty display,
unexpected readings, broken case, cracked test leads, etc) do not use
the tester and return it to Kewtech for repair.
9 For safety reasons only use accessories (test leads, probes, fuses,
cases, etc) designed to be used with this instrument and
recommended by Kewtech. The use of other accessories is prohibited
as they are unlikely to have the correct safety features.
10 When testing, always be sure to keep your fingers behind the safety
barriers on the test leads.
