Operation
For safe and reliable operation of your GaugeCalXP Pressure Comparator, please spend a few minutes reading the following instructions.
1 Mount the comparator to your bench or table: At higher pressures the force required to rotate the handle may cause the base of the comparator to lift. We recommend that the comparator be bolted to your bench or table. Refer to Figure 1 for the hole pattern and suggested bolt sizes.
2 Install the flange stem or stem adapters:
There are two (2) stainless steel flange bases. Each base has a 1/4” female (tapered) NPT thread. These bases are intended to have either a flange stem (Figure 2) or stem adapter (Figure 3) for quick connectors installed. It is possible to install an XP2i reference gauge directly into the base, but this is practical if only one XP2i will be regularly used with the comparator.
