Periodic maintenance requirement
Periodic maintenance is required to ensure sensors perform to expectation, given the range of possible
operating conditions they can face. Semiannually, a standard 4130 steel target in the size shown in
the table below should be used to verify the “Maximum Sensing Distance” for every sensor. See the
table below for standard target sizes and rated maximum sensing distances. This measurement must
also consider the temperature in the sensing environment and account for the possibility of up to 10%
temperature drift as shown in the table below. Any sensor that fails this periodic Maximum Sensing
Distance test should be immediately replaced.

All units referenced in this document meet the requirements of MIL-STD-461G CS114 with the exception of DC
models under certain specific conditions. DC models meet the requirements of the bulk cable injection test under all
conditions, above and below deck, but do not meet the requirements when the power conductor is tested individually
above deck, outside of a shielded junction box, over the 2 MHz–30 MHz frequency range.
