Fluke 87V EX Calibration Manual page 11

• Do not open function buttons inside the Meter. Interference or
damage to any of these elements removes the Ex-protection.
• Observe the tolerances or threshold values found in the
"Specifications" section of this manual.
• Use only allowed accessories with this Meter in Ex-hazardous areas.
See a listing of allowed Fluke accessories at www.Fluke.com.
• Avoid using the Meter in aggressive acidic or alkaline solutions.
• Do not use the Meter in zone 0.
• Never measure voltages greater than 65 volts in an Ex-hazardous
area.
• Never measure currents greater than 5 amps while using the Meter in
an Ex-hazardous area.
• Servicing not covered in this manual should be performed only by the
manufacturer. Repair or service by others may void the ATEX
certification of this Meter.
To avoid possible electric shock or personal injury in ALL areas
of operation, follow these guidelines:
•
Use this Meter only as specified in this manual or the protection
provided by the Meter might be impaired.
•
See the "ATEX Safety Information" section for additional warnings on
meter use in hazardous areas.
•
Do not use the Meter if it is damaged. Before you use the Meter,
inspect the case. Look for cracks or missing plastic. Pay particular
attention to the insulation surrounding the connectors.
•
Ensure the battery door is closed and latched whenever operating the
Meter.
•
Replace the battery as soon as the battery indicator (M) appears.
See "Replacing the Battery" section for instructions and a list of
approved batteries.
•
Remove test leads from the Meter before opening the battery door.
•
Inspect the test leads for damaged insulation or exposed metal.
Check the test leads for continuity. Replace damaged leads before
using the Meter.
•
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 when working with voltages above 30 V ac rms, 42 V ac
peak, or 60 V dc. These voltages pose a shock hazard.
•
Use only the replacement fuses specified in this Users Manual. See
"Replacing the Fuses" section for instructions and a list of approved
fuses.
•
Use the proper terminals, function, and range for measurements.
•
Avoid working alone.
•
When measuring current, turn off circuit power before connecting the
Meter to the circuit. Remember to place the Meter in series with the
circuit.
•
When making electrical connections, connect the common test lead
before connecting the live test lead; when disconnecting, disconnect
the live test lead before disconnecting the common test lead.
