Cleaning and storage
Tester does not need any special maintenance if used according to user manual.
Remove tester from all test points before cleaning.
Use a lightly damp cloth with neutral detergent for cleaning the instrument. Do
not use abrasives or solvents. After cleaning, do not use device until completely
dry.
Do not expose the instrument to direct sun light, high temperature and humidity
or dewfall.
Remove batteries when the instrument will not be in use for a long period to
prevent danger or damage due to possible battery leakage.
Safety advices
• Depending on the internal impedance of the voltage detector there will be a
different capability of indicating the presence or absence of operating voltage in
case of the presence of interference voltage.
• A voltage detector of relatively low internal impedance, compared to the reference
value of 100 kΩ, will not indicate all interference voltages having an original
voltage value above the ELV level. When in contact with the parts to be tested,
the voltage detector may discharge temporarily the interference voltage to a level
below the ELV, but it will be back to the original value when the voltage detector
is removed.
• When the indication “voltage present” does not appear, it is highly recommen-
ded installing earthing equipment before work.
• A voltage detector of relatively high internal impedance, compared to the
reference value of 100 kΩ, may not permit to clearly indicate the absence of
operating voltage in case of presence of interference voltage.
• When the indication “voltage present” appears on a part that is expected to be
disconnected of the installation, it is highly recommended confirming by another
means (e.g. use of an adequate voltage detector, visual check of the disconnec-
ting point of the electric circuit, etc.) that there is no operating voltage on the
part to be tested and to conclude that the voltage indicated by the voltage
detector is an interference voltage.
• A voltage detector declaring two values of internal impedance has passed a perfor-
mance test of managing interference voltages and is (within technical limits) able to
distinguish operating voltage from interference voltage and has a means to directly or
indirectly indicate which type of voltage is present.
