Ex Hazardous Areas
9
The safety features and integrity of the unit may be
compromised by any of the following:
• External damage to the housing
• Internal damage to the Calibrator
• Exposure to excessive loads
• Incorrect storage of the unit
• Damage sustained in transit
• Correct certification is illegible
• Functioning errors occur
• Permitted limitations are exceeded
• Functioning errors or obvious measurement
inaccuracies occur which prevent further
measurement by the Calibrator
• Opening the case
Safety Regulations
The use of the Calibrator meets the requirements of the
regulations providing that the user observes and applies
the requirements as stated in the regulations and that
improper and incorrect use of the unit is avoided.
• Use must be restricted to the specified application
parameters.
• Do not open the Calibrator.
• Do not remove or install the batteries within the
Ex-hazardous area. See “Ex Hazardous Areas”.
• Do not carry additional batteries within the
Ex-hazardous area. See “Ex Hazardous Areas”.
• Use only type tested batteries. The use of any other
batteries will invalidate the Ex-certification and
present a safety risk.
• Do not use the Calibrator in any circuit where the
voltage or transients may exceed 30 V.
• Only use the Calibrator in circuits with compatible
entity parameters. When the calibrator is used in an
Ex hazardous area, unless the area is known to be
safe, do not connect to any circuits that exceed the
entity parameters defined on Fluke 725Ex CCD
Control Drawing. See “Ex Hazardous Areas”.
