Infrared Gas Analyzer Operation 4

If the concentration detected is over range, the first line of the display blinks continuously.

4.8Programming

CAUTION: The programming functions of the Set Range and Curve Algorithm screens are configured at the facto- ry to the users application specification. These func- tions should only be reprogrammed by trained, qualified personnel.

To program, you must:

1.Enter the password, if you are using the analyzer’s password protection capability.

2.Connect a computer or computer terminal capable of sending an RS-232 signal to the analyzer RS-232 connector. (See chapter 3 Installation for details). Send the rp command to the analyzer.

Now you will be able to select the APPLICATION and ALGORITHM setupfunctions.

4.8.1 The Set Application Screen

The Set Application screen allows reprogramming of the three analysis ranges and the calibration range (including impurity gas, background gas, low end of range, high end of range, and % or ppm units). Original programming is usually done at the factory according to the customer’s application. It must be done through the RS-232 port using a computer running a terminal emulation program.

Note: It is important to distinguish between this System program- ming subfunction and the Range button function, which is an operator control. The Set Range Screen of the Application function allows the user to DEFINE the upper and lower limits of a range AND the application of the range. The Range func- tion only allows the user to select or define the limits, or to select the application, but not to define the application.

Normally the Model 7300A is factory set to default to manual range selection, unless it is ordered as a single-application multiple-range unit (in which case it defaults to autoranging). In either case, autoranging or manual range selection can be programmed by the user.
