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.
In order to display the version of the 3470, hold down while pow- ering up. The version will be displayed after the model name (3470). 8.4 Cleaning To clean the instrument, wipe it gently with a soft cloth moistened with water or mild detergent.
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).
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.
