Page 78: Shipping Check
In particular, check the accessories, panel switches, keys, and terminals. If the unit is damaged, or fails to operate according to the specifications, contact your dealer or HIOKI representative. Check the 3284 Unit and the Supplied Accessories...
Page 79: Safety
Safety DANGER This instrument is designed to comply with IEC 61010 Safety Standards, and has been thoroughly tested for safety prior to shipment. However, mishandling during use could result in injury or death, as well as damage to the instrument. Be certain that you understand the instructions and precautions in the manual before use.
Page 80 The following symbols in this manual indicate the relative importance of cautions and warnings. Indicates that incorrect operation presents an extreme hazard that could DANGER result in serious injury or death to the user. Indicates that incorrect operation presents a significant hazard that could WARNING result in serious injury or death to the user.
Page 81: Safety Symbols
Safety Symbols symbol printed on the instrument indicates that the user should refer to a corresponding topic in the manual (marked with the symbol) before using the relevant function. In the manual, the symbol indicates particularly important information that the user should read before using the instrument.
Page 82 Signifies the smallest display unit on a digital measuring instrument, i.e., the value displayed when the last digit on the digital display is "1". Safety...
Page 83 Measurement categories This instrument complies with CAT III safety requirements. To ensure safe operation of measurement instruments, IEC 61010 establishes safety standards for various electrical environments, categorized as CAT II to CAT IV, and called measurement categories. These are defined as follows. CAT II : Primary electrical circuits in equipment connected to an AC electrical outlet by a power cord (portable tools, household...
Page 84 viii Using a measurement instrument in an environment designated with a higher-numbered category than that for which the instrument is rated could result in a severe accident, and must be carefully avoided. Use of a measurement instrument that is not CAT- rated in CAT II to CAT IV measurement applications could result in a severe accident, and must be carefully avoided.
Page 85: Attentions During Use
When using an AC adapter, use only the specified HIOKI model 9445-02 or 9445-03 (for EU). WARNING To avoid electric shock, do not allow the product to get wet, and do not use it when your hands are wet.
Page 86 WARNING Do not input voltage exceeding 600 Vrms (1000 V max). To avoid electric shock when replacing the batteries, first disconnect the clamp portion from the object to be measured. Also, before using the product after replacing the batteries, replace the cover and screw.
Page 87 If you find any damage, contact your dealer or HIOKI representative. To avoid damage to the product, do not exceed the maximum input current rating, which depends on the frequency of the current being measured (see Fig.4) Be...
Page 88 CAUTION Do not store or use the product where it could be exposed to direct sunlight, high temperature or humidity, or condensation. Under such conditions, the product may be damaged and insulation may deteriorate so that it no longer meets specifications. Removable sleeves are attached to the metal pins at the ends of the test leads.
Page 89 xiii Accurate measurement may be impossible in NOTE locations subject to strong external magnetic fields, such as transformers and high-current conductors, or in locations subject to strong external electric fields, such as radio transmission equipment. Gently wipe dirt from the surface of the unit with a soft cloth moistened with a small amount of water or mild detergent.
Page 90 ― ― ― ― ― ― ― ― ― ― ― ― ― ― ― ― ― ― ― ― ― ― ― ― ― ― ― Due to the offset peculiar to elements from a hall NOTE effect, the display may sometimes not show 0 immediately after it is turned on, but this is not a malfunction.
