OPERATING INSTRUCTIONS

The XP2i-DP operates just like all the XP2i Series products. The uniqueness of the dierential pressure capability comes from the integration of the dieren-

tial sensor and process tting system. The keypad and remote functions are the same as on all XP2i Series products. For further details about these common
