XWWarning

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

• Use the Tester only as specified in this manual or the protection provided by the Tester might be

impaired.

• Do not use the Tester or test leads if they appear damaged, or if the Tester is not operating properly. If

in doubt, have the Tester serviced.

• Always use the proper terminal, switch position, and range for measurements before connecting Tester

to circuit under test.

• Verify the Tester’s operation by measuring a known voltage.

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

• Replace the battery as soon as the low battery indicator (b) appears.

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

continuity, diodes, or capacitance.

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

• When using the test leads, keep your fingers behind the finger guards.
