3. Basic safety measures
The basic safety guidelines and regulations of the relevant professional
associations apply.
Before turning on the ISOTEST
®
test equipment, the workplace should be
checked for potential obstacles and safety hazards, e.g., tripping hazards.
Intentional or inadvertent touching of a metal part possibly carrying high
voltage and an uncontrolled action resulting from this electric shock must
not lead to hazard for personnel. This also applies to working on ladders
and scaffolds.
Before insertion or removal of testing electrodes, the ISOTEST
®
test
equipment must be turned off using the main switch.
After turning on the unit with the main switch, the area behind the red
insulator (electrode clamping device) as well as the testing electrode in
the handle must not be touched.
During the tests, suitable work clothes and shoes meeting the
requirements of industrial safety regulations should be worn.
If tests are performed in small rooms or containers, the relevant safety
regulations and guidelines must be observed
(e.g., safety guards).
High-voltage sparks lead to the formation of ozone. To avoid excessive
ozone concentrations in rooms or containers, sufficient ventilation must
be provided.
Special care should be taken when using high-voltage extension cords or
extension bars as this will tamper safety shielding against accidental
contact with hazardous live adjacent to the electrode clamping device.
When using circular electrodes for testing the inner side of cylindrical
parts, the ISOTEST
®
test equipment must be turned off during insertion or
removal of the electrode.
