4.2.1.2 Setup Mode

The MAIN MENU consists of 14 functions you can use to customize and check the operation of the analyzer. Figure 4-1 shows the functions available with the 7300A. They are listed here with brief descriptions:

1AUTO-CAL:Used to define and/or start an automatic calibration sequence.

2PSWD: Used to establish password protection or change the existing password.

3LOGOUT: Logging out prevents unauthorized tampering with the analyzer settings.

4MODEL: Displays Manufacturer, Model, and Software version of the instrument.

5SELF-TEST: The instrument performs a self-diagnostic routine to check the integrity of the power supply, output boards, cell and amplifiers.

6SPAN: Set up and/or start a span calibration.

7ZERO: start a zero calibration.

8ALARMS: Used to set the alarm setpoints and determine whether each alarm will be active or defeated, HI or LO acting, latching or not, and failsafe or not.

9RANGE: Used to set up three analysis ranges that can be switched automatically with auto-ranging or used as individual fixed ranges.

10HARDW-VAR: This function displays parameters used by the software for some calculations. It is a troubleshooting tool to be used by qualified technicians.

11FILTER: This function sets the digital filter from 0 to 10, 0 being faster response time, and 10 being the slowest. The default is 4.

12CAL_OUTPUT: Calibrate Analog Output

13APPLICATIONS: Restricted function, not generally accessed by the end user. Used to define up to three analysis ranges and a calibration range (including impurity, background low end of range, high end of range, and % of ppm units).

14ALOGORITHM: Arestricted function, not generally accessed by the end user. Used to linearize the output for the range of interest.
