Overview
INTRODUCTION
Thank you for choosing the XP2i-DP Digital Test Gauge from Crystal Engineering Corporation. The XP2i-DP is a combination of leading edge
technology, double-sided isolated dierential pressure sensing, and rugged industrial design.
Overview 1
Based on the XP2i S
0.1% of reading accuracy wet/wet dierential transducer
•
Excellent performance in long term high vacuum applications
•
OPERATING INSTRUCTIONS
The XP2i-DP operates just like all the XP2i Series products. The uniqueness of the dierential pressure capability comes from the integration of the dieren-
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
eatures, refer to the XP2i Operation Manual (P/N 4870).
f
eries platform, the –DP has all the key features of the product line with additional capabilities that include:
