Faults And Damage; Safety Regulations - Fluke 707Ex Calibration Information Manual

XW Warnings and Cautions
To avoid electric shock, injury, or damage to the
mA Calibrator:
•
Use the mA Calibrator only as described in this
Calibration Information, the Users Manual, and
the Fluke 707Ex mA Calibrator CCD (Concept
Control Drawing) or the protection provided by
the mA Calibrator may be impaired.
•
Inspect the mA Calibrator before use. Do not
use it if it appears damaged.
•
Check the test leads for continuity, damaged
insulation, or exposed metal. Replace damaged
test leads.
•
Never apply more than 28 V between the input
terminals, or between any terminal and earth
ground.
•
Applying more than 28 V to the input terminals
invalidates the mA Calibrator's Ex Approval
and may result in permanent damage to the unit
so it can no longer be used.
•
Use the proper terminals, mode, and range for
your measuring or sourcing application.
•
To prevent damage to the unit under test, put
the mA Calibrator in the correct mode before
connecting the test leads.
•
When making connections, connect the COM
test probe before the live test probe. When
disconnecting, disconnect the live probe before
the COM probe.
•
Never use the mA Calibrator with the red
holster removed.
•
Never use the mA Calibrator with the case
open. Opening the case violates Ex Approval.
•
Make sure the battery door is closed before
using the mA Calibrator.
•
Replace the battery as soon as the M (low
battery) symbol appears to avoid false readings
that can lead to electric shock.
•
Remove test leads from the mA Calibrator
before opening the battery door.
•
This equipment is specified for use in
measurement category I (CAT I) pollution
degree 2 environments and should not be used
in CAT II, CAT III, or CAT IV environments.
Voltage transients should not exceed 300 V for
the CAT I applications where this product is
used. Measurement transients are defined in
IEC1010-1 as 2 µs rise time with a 50 µs
duration at 50 % of the maximum amplitude
height.
•
Measurement Category I (CAT I) is defined for
measurements performed on circuits not
directly connected to the mains.
•
Do not use in a damp or wet environment.

Faults and Damage

XW Warning
Applying a voltage greater than 28 V to the
input of the mA Calibrator invalidates its
Ex Approval and may impair its safe
operation in an Ex-hazardous area.
If there is any reason to suspect that the safe operation
of the mA Calibrator has been affected, it must be
immediately withdrawn from use, and precautionary
measures must be taken to prevent any further use of
the mA Calibrator in an Ex-hazardous area.
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 mA Calibrator
•
Exposure to excessive loads
•
Incorrect storage of the unit
•
Damage sustained in transit
•
Correct certification is illegible
•
Using the product with the red holster removed
•
Functioning errors occur
•
Permitted limitations are exceeded
•
Functioning errors or obvious measurement
inaccuracies occur which prevent further
measurement by the mA Calibrator

Safety Regulations

The use of this 707Ex mA Calibrator meets the
requirements of the regulations providing that the user
observes and applies the requirements as laid down 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 mA Calibrator.
•
Do not remove or install the battery within the
Ex-hazardous area.
•
Do not carry additional batteries within the
Ex-hazardous area.
•
Use only type-tested batteries. The use of any
other battery will invalidate the Ex-certification
and present a safety risk. Refer to Table 2.
•
Do not use the mA Calibrator in an Ex-hazardous
area unless it is completely and securely fitted in
its accompanying red holster.
