Abstract
A high flow calibration test point has entry, inlet, and outlet ports and a spring-biased plunger that in one position provides communication between the entry port and both the inlet and outlet ports, in another position provides communication between the entry port only with the outlet port, and in yet another position allows communication only between the inlet and outlet ports.
