Safety Information - Fluke 1550 Calibration Manual

Safety Information

In this manual, a Warning identifies conditions and actions that pose hazard(s) to the
user, a Caution identifies conditions and actions that may damage the MegOhmMeter or
the test instruments.
Before and after testing, confirm that the MegOhmMeter does not
indicate the presence of a hazardous voltage. If the MegOhmMeter
beeps continuously and a hazardous voltage is shown on the
display, disconnect test leads and remove power from the circuit
under test.
WXWarning: Read Before Using the MegOhmMeter
To avoid possible electric shock or personal injury:
•
Use the MegOhmMeter only as specified in this manual or the
protection provided by the MegOhmMeter might be impaired.
•
Do not disconnect the test leads before a 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 MegOhmMeter 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 MegOhmMeter if it looks damaged.
•
Take care 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 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 MegOhmMeter with any parts or cover
removed.
•
Disconnect the test leads from the circuit under test and from
the MegOhmMeter before changing the fuse.
•
Use only Fluke approved replacement fuses, parts, and
accessories as specified in this manual.
•
Do not use the MegOhmMeter if the safety shutter is impaired
in any way. The safety shutter 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 the Users Manual.
Do not allow other accessories or foreign objects to come
into contact with the guard terminal as safety may be
compromised.
