Safety Information

Understand and follow operating instructions carefully.

WARNING
Identifies hazardous conditions and actions that could cause BODILY HARM or DEATH.

CAUTION
Identifies conditions and actions that could DAMAGE the meter or equipment under test.

WARNING

• When using test leads or probes, keep your fingers behind the finger guards.
• Remove test lead from Meter before opening the battery door or meter case.
• Use the Meter only as specified in this manual or the protection by the Meter might be impaired.
• 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.
• Only replace the blown fuse with the proper rating as specified in this manual.
• Use caution with voltages above 30 Vac rms, 42 Vac peak,or 60 Vdc. These voltages pose a shock hazard.
• To avoid false readings that can lead to electric shock and injury, replace battery as soon as low battery indicator.
• Disconnect circuit power and discharge all high-voltage capaci-tors before testing resistance, continuity, diodes, or capacitance.
• Do not use Meter around explosive gas or vapor.
• To reduce the risk of fire or electric shock do not expose this product to rain or moisture.

CAUTION

• Disconnect the test leads from the test points before changing the position of the function rotary switch.
• Do not expose Meter to extremes in temperature or high humidity.
• Never set the meter in A function to measure the voltage of a power supply circuit in equipment that could result in damage the meter and the equipment under test.
