!Safety Information

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

capacitors before testing resistance, continuity, diodes, or

capacitance.

• Do not use Meter around explosive gas or vapor.

WARNING

Identifies conditions and actions that could DAMAGE the meter

or equipment under test.

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 Ω, , , , mA, 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.

CAUTION

Making Basic Measurements

Preparation and Caution Before Measurement

: Observe the rules of Warnings and Cautions

The figures on the following pages show how to make basic

measurements.

Caution

When connecting the test leads to the DUT (Device Under

Test) connect the common test leads before connecting the

live test leads; when removing the test leads, remove the live

test leads before removing the common test leads.
