Working with the instrument:
• Equipment under test must be switched off (i.e. de-energized) before test leads are con-
nected to the equipment.
• Do not touch any conductive parts of equipment under test during the test.
• Make sure that the tested object is disconnected (mains voltage disconnected) before start-
ing the Insulation Resistance measurement!
• Do not touch the tested object whilst testing it, risk of electric shock!
• In case of a capacitive test object (long tested cable etc.), automatic discharge of the object
may not be done immediately after finishing the measurement – “Please wait, discharging”
message will be displayed.
Handling with capacitive loads:
• Note that 40 nF charged to 1 kV or 9 nF charged to 5 kV are hazardous live!
• Never touch the measured object during the testing until it is totally discharged.
• Maximum external voltage between any two leads is 600 V (CAT IV environment).
Important Safety Information
