Pyrotechnic ohmmeter / Safety megohmmeter

AOIP designed a pyrotechnic ohmmeter / safety megohmmeter particularly adapted to measurements on pyrotechnical elements.

The instruments perform 4-wire continuity and / or insulation measurements, allowing to annihilate line resistance and get accurate measured values.

Measurement conditions for pyrotechnics

  • Measuring current much lower than the current of non-fire
  • Connection to the test line only for the activated period of measurement
  • Discharge of any residual electrical charges

Safety conditions for pyrotechnics

  • No overshoot of maximum current even in case of instrument failure (electronics breakdown, internal short-circuit…)
  • Permanent self-checking of the instrument internal functions before connection to measurement channel
