Page 6: General Overview
Pressure demands from a Beamex pressure calibrator via an RS232 interface are converted by POC4 into a regulated pressure supplied from a line or bottle source. Option B provides negative pressure calibration. -
Page 7: Unpacking And Inspection
1.1 Unpacking and Inspection At the factory each new POC4 passes a careful inspection. It should be free of scrapes and scratches and in proper operation order upon receipt. The receiver should, however, inspect the unit for any damage that may have occurred during transit. -
Page 8: Safety
Do not apply a pressure greater than the maximum pressure stated. * A qualified person must have attended a product training course given by the manufacturer or appointed agent and successfully completed the training course on this equipment. POC4 - General A - 3... -
Page 9: Functional Description
When using POC4 together with Beamex pressure calibrators, no programming or specific commands are required. The calibrator supervises the use of POC4. POC4 can be configured in a number of different ways as detailed in Section C. This section also details the installation procedures. -
Page 10: Analogue Circuit Operation
Setpoint demand and the actual output of POC4. This error is first processed by an Error Signal Processing circuit, under the control of the microprocessor, to drive a pulse width modulator. The output of the pulse width modulator drives the Apply and Release valves to change the output pressure in an appropriate direction to correct the error i.e. - Page 11 As the desired pressure is reached the pressure calibrator shuts POC4 off. This is done in order to have as few disturbing variables as possible while measuring the calibration point.

Page 12: Installation
3 INSTALLATION Usually POC4 is already installed in a MCS100 Bench or Table Top system or separately in a 19" rack. Also all the necessary connections are already done. These following chapters are only necessary during uninstallation and reinstallation of POC4. -

Switch off the power supply to the instrument. 3.3 Communications Interface Connections Only the RS232 connector in the rear panel of POC4 is used when connecting a Beamex pressure calibrator to POC4. Use the RS4 cable supplied with POC4. Also remember to set the switch labeled STACKING on the rear panel to the 0 position. -

Note: POC4 measures the output pressure only for its own needs. When the requested pressure level is reached, according to POC4, the pressure calibrator measures the actual pressure and this value is used when the calibration point is stored. - Page 18 B - OPERATION...

1 GENERAL POC4 may be controlled with any computer with a suitable software for serial communication installed. This manual includes only the simplest way of utilizing POC4: in connection with Beamex pressure calibrators. No special skills are needed when using POC4 the aforementioned way; just make the necessary connections described in the next chapter and perform the calibration using the calibrator at hand. -

Usually it is on the rear panel. On POC4 it’s a 9-pin RS232 connector and on the pressure calibrator it is a 25-pin RS232 connector marked options or RS232. -
Page 21: Serial Communication
2.1 Serial communication Both POC4 and the Beamex pressure calibrator to be connected to POC4 need to have suitable settings. Otherwise the communication will not succeed resulting in an unsuccessful calibration. 2.1.1 Beamex pressure calibrator settings Pressure calibrator (PC104, PC106 or PC106P):... -

Setup mode is used to set up the instrument's default control parameters to those required for the particular mode of operation. When the instrument is delivered, the parameters are preset. Normal use of POC4 does not require any changes in configuration settings.
