Safety Information

"Warning" and "Caution" Statements

A “XW Warning" identifies hazardous conditions and actions that could cause bodily harm or death.

A "W Caution" identifies conditions and actions that could damage the Meter, the equipment under test, or cause

permanent loss of data.

XWWarnings and Precautions

To avoid possible electric shock or personal injury, follow these guidelines:

• Use the Meter only as specified in this manual or the protection provided by

the Meter might be impaired.

• Do not use the Meter or test leads if they appear damaged, or if the Meter is

not operating properly.

• Always use proper terminals, switch position, and range for measurements.

• Verify the Meter's operation by measuring a known voltage. If in doubt, have

the Meter serviced.

• Do not apply more than the rated voltage, as marked on Meter, between

terminals or between any terminal and earth ground.

• Use caution with voltages above 30 V ac rms, 42 V ac peak, or 60 V dc.

These voltages pose a shock hazard.

• Disconnect circuit power and discharge all high-voltage capacitors before

testing resistance, continuity, diodes, or capacitance.

• Do not use the Meter around explosive gas or vapor.

• When using test leads or probes, keep your fingers behind the finger

guards.

• Remove test leads from Meter before opening the battery door or Meter

case.

• Comply with local and national safety requirements when working in

hazardous locations.

• Use proper protective equipment, as required by local or national authorities

when working in hazardous areas.

• Avoid working alone.

• Use only the replacement fuse specified or the protection may be impaired.

• Check the test leads for continuity before use. Do not use if the readings are

high or noisy.

• Do not use the Auto-V LoZ function to measure voltages in circuits that

could be damaged by this function’s low input impedance (≈3 kΩ) (114, 116

and 117).
