5. Use 1) To prevent differential gauge measuring set damage, operate the differential gauge along with the 3-way or 5-way manifold all the time and check both the high and low sides before it is installed on the manifold. 2) The differential gauge should be installed as a higher position than the pressure diffuser during gas differential pressure measurement and lower than it during liquid differential pressure measurement. -

6. OPERATIONS 6-1) Operation of the 3-way valve ① Equalizing Valve ② Low Pressure Valve (LP Valve) ③ High Pressure Valve (HP Valve) Fig. 6-1 (1) For initial setup, all the valves must be closed (2) After complete installation, first release Equalizing valve, then replease HP valve at this point check whether the pointer is pointing at "0", if there is an error, must perform zero adjustment. - Page 9 6-3) Operation of the 5-way valve ①② Equalizing Valve ③ Low Pressure Valve (LP V/V) ④ High Pressure Valve (HP V/V) ⑤ Bleed Valve (Vent valve) Fig. 6-2 (1) For initial setup, all the valves must be closed (2) After complete installation, first release Equalizing valve, then replease HP valve at this point check whether the pointer is pointing at "0", if there is an error, must perform zero adjustment.
