• Use proper protective equipment, as required by local or national authorities when working in hazardous areas. • Comply with local and national safety requirements when working in hazardous locations. WCaution To avoid possible damage to the Meter or to the equipment under test, follow these guidelines: • Disconnect circuit power and discharge all high-voltage capacitors before testing resistance, continuity, diodes, or capacitance. • Use the proper terminals, function, and range for all measurements. True-rms Digital Multimeters Hazardous Voltage • Do not remove batteries while the Meter is turned on or a signal is applied to the Meter's input jacks. • Before measuring current, check the Meter's fuses. (See "Testing the Fuses" in the Users Manual on the accompanying CD.) • Do not use the LoZ mode to measure voltages in circuits that could be damaged by this mode's low impedance (≈3 kΩ). (Model 289 only) Hazardous Voltage To alert you to the presence of a potentially hazardous voltage, when the Meter detects a voltage ≥30 V or a voltage overload (OL), the Ysymbol is displayed. 3 MyFlukeStore Shop for Fluke products online at: www. .com 1.888.610.7664
