Flex current clamps A 1446

3 Safety

Read the operating instructions before use and follow all safety instructions.
If the test equipment is used in a manner that is not specified in this user manual,
the protection provided by the equipment might be impaired!
Adhere to local and national safety codes. Individual protective equipment must
be used to prevent shock and arc blast injury where hazardous live conductors
are exposed.
Before each use, inspect the Current Clamps and its latching system for any
damage. Pay particular attention to the insulation surrounding the flexible
measuring head. Look for cracks or missing portions of the clamp housing or
output cable insulation. Also look for loose or weakened components. Don't use
a flexible current sensor if the wear indicator of the JAW END or wear indicator of
the flexible cord used for the JAW of the flexible current sensor is visible.
Do not use a clamp that is cracked, damaged, or has a defective cable.
Never use the clamp on a circuit with voltages higher than 1000 V CAT III or
600V CAT IV.
De-energize the installation on which current will be measured or adopt safe
operating procedures during application and removal of the current clamp.
Use extreme caution when working around bare conductors or bus bars.
Do not use the Current Clamp to measure bare conductors carrying a voltage
from 30V up to 1000V unless you are wearing protective clothing suitable for
high-voltage work. Contact with the conductor could result in electric shock.
Always use appropriate equipment for personal protection.
Do not apply around or remove from UNINSULATED HAZARDOUS LIVE
conductors, which may render electric shock, electric burn, or arc flash.
Use caution when working with voltages above 60 V dc, 30 V ac rms or 42 V ac
peak. Such voltages pose a shock hazard.
