    • Read “Safety Information” before using this Meter. The Fluke 15B and 17B Multimeters (hereafter referred to as “the Meter”) are battery operated, 4,000 count instruments, with a digital display. Except where noted, the descriptions and instructions in this manual apply to both models of the Meter.

  • Page 10: Safety Information

    15B & 17B Calibration Manual Safety Information The Meters comply with IEC 1010-1 CAT I 1000 V, CAT II 600 V, and CAT III 300 V overvoltage standards. Refer to “Specifications” for more information. In this manual, a Warning identifies conditions and actions that pose hazards to the user.

  • Page 11: International Electrical Symbols

    Digital Multimeter Safety Information • For all dc functions, including manual or auto-ranging, to avoid the risk of shock due to possible improper reading, verify the presence of any ac voltages by first using the ac function. Then select a dc voltage range equal to or greater than the ac range.
