Inspection
To maintain operator safety and ensure reliability of the A 1398 PQA Iron Current Clamp, it is
good practice to inspect it on a regular basis. Check that the enclosure and optional connection
are without defects such as scratches or breaks.
Jaw surface must be clean. Pollution on jaw surfaces reduces the current clamp sensitivity.

No special maintenance is required for the housing. To clean the surface of the A 1398 PQA use
a soft cloth slightly moistened with soapy water or alcohol. Then leave the A 1398 PQA to dry
totally before use.
