content: Below sequence of photos showing how to hack the lock used to prevent unauthorized calibration.It works with Datron 1271/81 but should also be suitable for most instruments with white front panel.It is fine unless the equipment is used in student's lab.Open the top cover to access to internal side of the rear panel.Use screwdriver to unlock two plastic holders. Do this VERY gently not to break old material.Use pilers to unscrew the nut.Mark the proper position before removing the lock from the panel.
