• This document is not a supplement to the operating manual! The operating manual can be found on the product website of the BENNING IT 115 for free download in PDF format. http://tms.benning.de/it115

• If the test equipment is used in a manner not specified in this user manual, the protection provided by the equipment could be impaired!

• Read this user manual carefully, otherwise the use of the instrument may be dangerous for the operator, the instrument or for the equipment under test!

• Do not use the instrument or any of the accessories if any damage is noticed!

• Consider all generally known precautions in order to avoid risk of electric shock while dealing with hazardous voltages!

• If the fuse F1 has blown, please follow the instructions of this operating manual to replace it! Only use a fuse complying with the specification (see chapter 7.1) as replacement.
  If one of the fuses F2 or F3 has blown, the device must not be used anymore. In this case, the device must be sent to BENNING for inspection and repair.

• Do not use the instrument in AC supply systems with voltages higher than 550 V AC.

• Service, repairs or adjustment of instruments and accessories is only allowed to be carried out by a competent authorized personnel!

• Please use standard or optional BENNING accessories only which are available from your authorized specialty retailer!

• Consider that protection category of some accessories is lower than of the instrument.
  Test tips and Tip “Commander” have removable caps. If they are removed the protection falls to CAT II. Check markings on accessories!
  cap off, 18 mm tip: CAT II up to 1000 V to earth
  cap on, 4 mm tip: CAT II 1000 V / CAT III 600 V / CAT IV 300 V to earth

• The instrument come supplied with rechargeable NiMh battery cells. The cells should only be replaced with the same type as defined on the battery compartment label or as described in this manual. Do not use standard alkaline battery cells while the power supply adapter is connected, otherwise they may explode!

• Hazardous voltages exist inside the instrument. Disconnect all test leads, remove the power supply cable and switch off the instrument before removing battery compartment cover.

• All normal safety precautions must be taken in order to avoid risk of electric shock while working on electrical installations!

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 (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 deenergized 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!
