1 Safety
Notice
Electricity can cause severe injuries even with low voltages
or currents. Therefore it is extremely important that you
read the following information before using this Tester.
1.1 This instrument must only be used by a competent trained
person and in strict accordance with the instructions.
Kewtech will not accept liability for any damage or injury
caused by misuse or non-compliance with instructions or
safety procedures.
1.2 This instrument is only intended for single phase operation,
230V AC+10%-15% phase to earth or phase to neutral
operation. Although fully protected (no bangs), it must never
be connected phase to phase (400 VAC).
1.3 When conducting a test, particularly on earth spikes, do not
touch any exposed metal work. This is because the earth has
a current flowing through it for the duration of the test.
1.4
Never open the instrument case
(except for battery
replacement and in this case disconnect all leads first)- there
are dangerous voltages present. Only trained, competent
Electronic engineers should open the case. Send the unit to
Kewtech, if a fault develops.
1.5 This instrument is primarily protected by HRC Ceramic
fuses. Do not attempt to replace them if they fail. If they do,
contact Kewtech.
1.6 If the overheat symbol appears in the display, disconnect the
instrument from the mains and allow to cool down.
1.7 When testing, always be sure to keep your fingers behind
the safety barriers on the test leads.
1.8 Always inspect your Instrument and test leads before use for
any sign of abnormality or damage. If any abnormal
conditions exist (broken test leads, cracked case, display
faulty, inconsistent readings, etc) do not attempt to take any
