True-rms Digital Multimeters

Hazardous Voltage

• 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.

• 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.
