ROC800-Series Instruction Manual

Revised Jul-14

General Information

1-17

The AGA 8 method calculates the compressibility factor based on the

physical chemistry of the component gasses at specified temperatures

and pressures.

The firmware supports liquid calculation methods ISO 5167 and API

12. You must supply factors for API 12 correction through a Function

Sequence Table (FST) or user program. For more information, refer to

the

Function Sequence Table (FST) User Manual

(Part Number

D301058X012).

Note

:

For a complete and current listing of all supported liquid and/gas

calculations on the ROC800, refer to the technical specifications

ROC800-Series Operating System Firmware

(ROC800:FW1).

1.5.5 Automatic Self Tests

The operating system firmware supports diagnostic tests on the ROC800

hardware, such as RAM integrity, Real-Time Clock operation, input

power voltage, board temperature, and watchdog timer.

The ROC800 periodically performs the following self-tests:
