DANGER
● This instrument is intended only for use in single phase operation
at 230V +10% -15% AC phase to earth or for use in OLD-TT
system phase to neutral.
● When conducting tests do not touch any exposed metalwork
associated with the installation. Such metalwork may become live
for the duration of the test.
● When testing, always be sure to keep your fingers behind the
safety barriers on the test leads.
● Be sure to remove the test lead from the mains power supply
promptly after measurement. Do not leave the instrument
connected to the mains power supply for a long time.
WARNING
●
Never open the instrument case
- there are dangerous voltages
present. If a fault develops, return the instrument to your distributor
for inspection and repair.
● If the overheat symbol appears in the display (
) disconnect the
instrument from the mains supply and allow to cool down.
● 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.
● Never attempt to use the instrument if the instrument or your hand
is wet.
CAUTION
● For those testers without the D-LOK circuitry (models 4116A,
4118A) all RCD's (RCCB, ELCB) in the circuit must be by-passed
for the duration of the test (except on loop-2000Ω range).
Do not operate the RCD Test Button with the RCD by-passed.
● 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.
● Use a damp cloth and detergent for cleaning the instrument. Do
not use abrasives or solvents.
