The LiMAR Spring Jar Calibration Sub is used to confirm the activation point or ‘trip’ setting of the LiMAR Adjustable Spring Jar prior to running in hole.
The LiMAR Calibration Sub is made up to the Adjustable Spring Jar and by simply rotating the tommy bar at the end of the Calibration Sub load is applied across the latch mechanism of the Spring Jar. Simultaneously, a hydraulic piston will compress a fluid filled chamber and the resultant pressure created is registered on the pressure gauge in psi. This reading is directly proportionate to the tripping force in pounds force and indicates the tension required to activate the Spring Jars down hole.
