Operation Electromagnetic compatibility (EMC) Electromagnetic compatibility refers to the ability of the Hilti PD 20 to function correctly in an environment where it is exposed to electromagnetic radiation and electrostatic discharge, without causing electromagnetic interference to other devices. WARNING There may be a possibility of interference with other equipment due to electromagnetic radiation. Although the Hilti PD 20 complies with the strict requirements of the relevant directives and standards, Hilti cannot entirely rule out the possibility of interference with other equipment. CAUTION Measurements may exceed tolerances in the event of interference caused by electromagnetic radiation. Although the Hilti PD 20 complies with the strict requirements of the relevant directives and standards, Hilti cannot entirely rule out the possibility of the Hilti PD 20 being subject to interference caused by very intense electromagnetic radiation, e. g. in the immediate vicinity of radio transmitters, radio communication equipment, diesel generators, etc. Check the readings for plausibility when measuring under these conditions. 3.
