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 and the actual
voltage 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)
– "Commander" test plug for shock-proof socket (optional)
Measuring category of commanders:
Tip "Commander" (cap off, 18 mm tip) ... CAT II 1000 V to earth
Tip "Commander" (cap on, 4 mm tip) ..... CAT II 1000 V / CAT III 600 V / CAT IV 300 V to earth
"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"!
