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.
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 these instructions.
They must always be observed when using the instrument.
3 This instrument is designed to work in distribution systems where the line to earth has a
maximum voltage of 300V 50/60Hz and for some ranges where line to line has a
maximum voltage of 500V 50/60Hz.
Be sure to use it within this rated voltage.
For use in the continuity testing and insulation testing modes this instrument
must be
used ONLY on circuits which are de-energized.
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 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 your
distributor for repair.
8 For safety reasons only use accessories (test leads, probes, fuses, cases, etc) designed
to be used with this instrument and recommended by KYORITSU. The use of other
accessories is prohibited as they are unlikely to have the correct safety features.
9 When testing, always be sure to keep your fingers behind the finger guards on the test
leads.
10 During testing it is possible that there may be a momentary degradation of the reading
due to the presence of excessive transients or discharges on the electrical system under
test. Should this be observed, the test must be repeated to obtain a correct reading. If in
doubt, contact your distributor.
