Safety Information - Fluke 1550 User Manual

Safety Information

Before and after testing, confirm that the Meter does not indicate the
presence of a hazardous voltage. (See Figure 3.) If the Meter beeps
continuously and a hazardous voltage is shown on the display,
disconnect test leads and remove power from the circuit under test.
• To avoid possible electric shock or personal injury:
• Use the Meter only as specified in this manual, or the protection
provided by the Meter might be impaired.
• Do not disconnect the test leads before the test has been completed
and the test voltage at the terminals has returned to zero. This
ensures that any charged capacitance is fully discharged.
• Ensure there is no power to the circuit under test and that all circuit
capacitances are fully discharged prior to testing with this
instrument.
• Avoid working alone or around explosive gas, vapor or dust.
• Do not use the Meter in a wet environment.
• Inspect the test leads for damaged insulation or exposed metal.
Check test lead continuity. Replace damaged leads. Do not use the
Meter if it looks damaged.
• Be careful when working above 30 V ac rms, 42 V ac peak and 60 V
dc. Such voltages pose a shock hazard.
• When using the probes, keep your fingers behind the finger guards.
• Measurements can be adversely affected by impedances of
additional operating circuits connected in parallel.
• Place test leads in proper input terminals.
• Do not use the Meter with any parts or cover removed.
• Disconnect the test leads from the circuit under test and from the
Meter before changing the fuse.
• Use only Fluke approved replacement fuse(s), parts, and accessories
as specified in this manual.
• Do not use the Meter if the safety shutter is impaired in any way. The
safety shutter (see Frontispiece) prevents access to the test
terminals and charger terminals at the same time.
• There are no user replaceable parts inside the instrument.
•
Use the guard terminal only as specified in this manual. Do not allow
other accessories or foreign objects to come into contact with the
guard terminal as safety may be compromised.
