Yokogawa also provides a wide selection of high shock meters ( AB/DB 14 ) for most voltage and current applications. These meters meet military specifications MIL-M-16034 and MIL-S-901 for use in severe shock and vibration conditions.
The AB/DB 14 Switchboard meters conform to military specifications, namely MIL-S-901 and MIL-M-16034. Its primary application is for high shock conditions such as shipboaed control panels.
