    6.1 Outputting Waveform and Resultant RMS Values Advanced Measurements 6.1 Outputting Waveform and Resultant RMS Values Do not simultaneously connect the USB and output terminals of the tester to external devices. If the ground potential of the device connected to the USB terminal differ from that of the device connected to the output terminal, a short circuit current could flow via the FT3470-50 and damage the device connected to the USB terminal by fire.
  • Page 102 6.1 Outputting Waveform and Resultant RMS Values • Do not short circuit the output terminals or apply a voltage as this could damage them. • When connecting the tester to an insulation BNC, connect the 9759 Output Cable to a 9489 Extension Cable before connecting it to an insulation BNC.

  • Page 117: Maintenance And Service

    When sending the instrument for repair, remove the batteries and pack carefully to prevent damage in transit. Include cushioning material so the instrument cannot move within the package. Be sure to include details of the problem. Hioki cannot be responsible for damage that occurs during shipment.

  • Page 118: Error Indication

    We recommend that the calibration period be determined in accordance with the status of the instrument or installation environment. Please contact your Hioki distributor to have your instrument periodically calibrated. • Since the tester must be calibrated together with the magnetic field sensor, send in both the tester and the magnetic field sensor when re- calibration is required.

    Appendix 1 ICNIRP Guideline (Basic Restrictions) Appendix Appendix 1 ICNIRP Guideline (Basic Restrictions) The exposure levels set for this tester are based on the ICNIRP (Interna- tional Commission on Non-Ionizing Radiation Protection) Guidelines. Basic restrictions apply to current density, SAR and power density. Threshold values have been set on the levels of these physical quanti- ties that affect human health (for example, headaches).

  • Page 120: Appendix 2 Coupling Factor In The Icnirp Guidelines

    Appendix 2 Coupling Factor in the ICNIRP Guidelines Appendix 2 Coupling Factor in the ICNIRP Guidelines The degree of coupling (coupling factor) of the human body and a mag- netic field changes the effect on the human body. Coupling factor a is 0  a  1, where 0 is no coupling and 1 is maximum coupling.
