Handheld Analyzers

JLG has made two different shaped analyzers over the years—square and T-shaped. Our handheld analyzers 2901443 are used for diagnostic programming and troubleshooting on aerial work platforms. Both will perform the same functions and work on all machines that accept an analyzer. These should not be confused with the “calibrator” that is used on Sevcon motor controllers, as that is totally different and not compatible.
