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. It must
never
be connected phase to phase -
damage will result.
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 (approx.) 20ms).
1.4
Never open the instrument case
- 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 using the KT41 all RCDs in the circuit must be by-
passed for the duration of the test. Do
not
operate the
RCD Test button with the RCD by-passed.
1.8 This unit is designed to give minimum ‘splash’ when
connecting to an earth point when using the external earth
probe. To reduce the effect further, always connect the
