Security megohmmeter IND 44

digitalbench-topfor pyrotechnic devices

This safety megohmmeter was developed to carry continuity and isolation measurements on pyrotechnical elements where user safety is at stake. Two types of conditions define the user safety: Measurement conditions: - Measuring current much lower than the current of non-fire - Connection to the test line only for the activated period of measurement - Discharge of residual electrical charges Safety conditions: - 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
