BENNING IT 115 Short instructions 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

BENNING IT 115 Short instructions 1.4 Indications and meaning of symbols Terminal voltage monitor The terminal voltage monitor displays on-line the voltages on the test terminals and information about active test terminals in the AC installation measuring mode. The voltage applied is displayed by means of the testing terminal symbol. All three testing terminals L, N and PE are used for the selected measurement. The voltage applied is displayed by means of the testing terminal symbol.

BENNING IT 115 Short instructions The test cable resistance for the low-impedance measurement / continuity test has been compensated. High resistance to earth of test probes. Results may be impaired. Measured signal is out of range (clipped). Results are impaired. Fuse F1 is broken. Sound warnings Continuous sound Warning! Dangerous voltage on the PE terminal is detected. Evaluation of the measuring result Measurement result is inside pre-set limits (green LEDs).
