4.6 Service Test Points
Service tests points can be found on the PanaFlow Z3 Main board just inside the front cover. There are 6 pins found on
the bottom left front side of the main PCB that are accessible to service personnel. These test points are easily
connected by standard oscilloscope probes and allow the service person to look at critical signals.
Figure 42: Service Test Points
The test points are:
GATE: Gate connection is input to start and stop flow calibration process. This input detects an outside source
contact closure. A closure can be programmed to stop totals or clear totals. Use DRTN along with GATE.
RCV: Receive signal allows the user to look at the receive signal before it is processed by the meter. It is usually
looked at along with the TWIND and RWIND. Use ARTN with RCV signal.
