SAFE TESTING (READ BEFORE USING)
Electricity is dangerous and can cause injury and death. To avoid possible
electric shock, personal injury or damage of instrument, 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 noncompliance 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 only intended for single phase operation at 230V AC
+10%, -15% phase to earth or phase to neutral operation, and then only for
Loop, RCD and Uc testing. For use in the continuity testing and insulation
testing modes this instrument must be used ONLY on circuits
which are de-energized.
4. Verify the tester's operation by measuring a known voltage before and
after using it.
5. When conducting tests do not touch any exposed metalwork associated
with the installation. Such metalwork may become live for the duration of
the test.
6. 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.
7. If the overheat symbol appears in the display "
instrument from the mains supply and allow to cool down.
8. 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.
9. 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.
10. 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.
11. When testing, always be sure to keep your fingers behind the safety
barriers on the test leads.
12.
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.
13.
The sliding shutter on the back of the instrument is a safety device. The
instrument should not be used if it is damaged or impaired in any way, but
#

returned to your distributor for attention.
14.
Do not operate the function switch while the instrument is connected to a
circuit. If, for example, the instrument has just completed a continuity test
and an insulation test is to follow, disconnect the test leads from the circuit
before moving the function switch.
15. Do not rotate function switch when test button is depressed. If the function
switch is inadvertently moved to a new function when the test button is
depressed or in lock-down position the test in progress will be halted. To
reset, release test button and press again to restart testing on new function.
16.
THE WIRING CHECK LED (P-E, P-N) of this instrument is to protect the user
from electrical shock resulting from incorrect connection of Line and Neutral
or Line and Earth.When the Neutral and Earth conductors are incorrectly
wired, the WIRING CHECK LED function cannot identify the incorrect
connection. Other procedures and test must be conducted to check and
confirm that the wiring is correct prior to making measurement. Do not use
this instrument to check the correct wiring of the power supply. Kyoritsu will
not be held liable for any accident that may result from incorrect wiring of
the power supply line.
17.
Use a damp cloth and detergent for cleaning the instrument. Do not use
abrasives or solvents.
