AEMC ALS-1 [2121.05] Line Splitter. The AC Line Splitter Model ALS-1 increases the sensitivity of clamp-on current probes and clamp-on meters. The Model ALS-1 provides temporary separation of conductors (avoiding splitting of the line) to facilitate measurement of current. Simply plug the Model ALS-1 into a connector for a safe measurement. Two clamp positions are available: X1 for direct readings, and X10 for actual reading multiplied by 10. Also features voltage checking.
