Page 9: Introduction
Fluke 183 &185 True RMS Digital Multimeters Introduction The Fluke 183 and 185 True RMS Digital Multimeters (hereafter referred to as "the meter") are handheld, battery-operated instruments that measure and source electrical and physical parameters. These Meters comply with IEC 1010 edition for CAT III 1000 V and CAT IV 600 V environments. -
Page 10: Safety Information
183 & 185 Users Manual Safety Information Review the following safety precautions to avoid injury and prevent damage to the meter or any products connected to it. To avoid potential hazards, use the meter only as specified Safety Terms The following terms appear in this manual: Warning statements identify conditions or practices that could Warning result in injury or loss of life. -
Page 11: Safety Precautions
Do not use the meter within 1-inch (2.54 cm) of strong external magnetic fields such as that produced by the Fluke ToolPak hanging magnet accessory. Incorrect readings may result. If erratic behavior is noted, turn meter off to reset. - Page 12 183 & 185 Users Manual WWarning To avoid possible electric shock or personal injury, follow these guidelines: Before and after measuring hazardous voltages ( 30 V ac rms, 42 V peak, or 60 V dc), verify the meter’s proper operation by measuring a known voltage. Do not use the meter if it is damaged.
- Page 13 True RMS Digital Multimeters Safety Information Connect the common test lead before you connect the live test lead. When you disconnect test leads, disconnect the live test lead first. Remove test leads from the meter before you open the battery door. Do not operate the meter with the battery door or portions of the cover removed or loosened.
