Fluke 77 User Manual page 4

To avoid possible electrical 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. If in doubt, have the
Meter serviced.
Always use the proper terminals, switch position, and range for measurements.
Verify the Meter's operation by measuring a known voltage.
Do not apply more than the rated voltage, as marked on the Meter, 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.
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 the test leads, keep your fingers behind the finger guards.
Remove test leads from the Meter before opening the Meter case or battery door.
