With our V100 and V200 Fail Freeze positioners, users need to be aware that the Fairchild 6100 series Fail Freeze I/P is orientation sensitive. This means that if the positioner is calibrated at one orientation in the shop, and installed in a complete different orientation the zero and span can shift. If this does occur it is a very simple process to calibrate the I/P back to it’s correct parameters. We have developed a simple calibration sheet (PDF) that can be found by CLICKING HERE.
