BENNING IT 130
Warnings related to safety – measurements
Insulation resistance
Insulation resistance measurement should only be performed on de-energized objects!
Do not touch the test object during the measurement or before it is fully discharged! Risk of
electric shock!
When an insulation resistance measurement has been performed on a capacitive object,
automatic discharge may not be done immediately! The warning message
voltage (Udisch) are displayed during discharge until voltage drops below 30 V.
Do not connect test terminals to external voltage higher than 600 V (AC or DC) in order not to
damage the test instrument!
Low-impedance resistance/continuity test
Low-impedance resistance measurements/ continuity tests should only be performed on de-
energized objects!
Parallel loops may influence on test results.
Testing PE terminal
If the phase voltage is detected at the protective conductor connection PE, immediately stop all
measurements and ensure that the fault of the installation will be eliminated.
Warnings related to safety – batteries/ storage batteries and fuses
Disconnect all test cables / accessories from the tester and from the installation and switch the
tester off before opening the cover of the battery / fuse compartment. Dangerous voltages
may be applied to the interior of the tester!
Please make sure that the storage batteries are inserted correctly, because otherwise the tester
is not ready for operation and the storage batteries will discharge.
Do not recharge alkaline battery cells!
The storage batteries must be charged only by means of the charger included in the scope of
delivery!
Warnings related to safety – "Commander" probe tip (included in delivery)
Measuring category of commanders:
"Commander" probe tip (cap off, 18 mm tip)
"Commander" probe tip (cap on, 4 mm tip)
"Commander" test plug for shock-proof socket CAT II 300 V to earth
Measuring category of commanders can be lower than protection category of the instrument.
If dangerous voltage is detected on the tested PE terminal, immediately stop all measurements,
find and remove the fault!
Disconnect the "Commander" from the tester and from the installation and switch the
"Commander" off before opening the cover of the battery compartment. Dangerous voltages
might occur inside the "Commander"!
