Digital ohmmeter IND 43

bench-topsecurity4-wire

This safety ohmmeter 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
