 Instrument Controls and Key Pad for PE 3030B

 

303 Key PadThe instrument key pad controls and screen have the following functions.

1. POWER ON/OFF Switch to the left of the monitor and controls the line power to the instrument.

2. The READ key and Indicator light to the left of the key pad. Depression of this key activates a read or measurement cycle only when the instrument is in the RUN mode. The Read indicator lights when measurement begins and goes out upon completion of the cycle. The results are displayed on the CRT screen in a format selected by the operator.

3. ELEMent SELECT key begins at the top left of the key pad and is the first column. Depression of this key with on pending entry calls up the "cookbook" index to the screen. The index displayed is either FLAME, HGA, or MHS, depending on which system disk is being used. Entering the atomic number and then pressing this key displays the Flame Analytical Conditions for the element selected.

4. PROGram Key, is below the Element Select Key. Depression of this key calls up the Programming Mode screen were twenty-one instrument operating parameters can be entered.

5. SETUP Key is below the Program Key. Depression of this key calls up the Setup Mode screen for the element selected. Lamp alignment and wavelength adjustments can be performed in this move by using the bar graphics displayed on the screen.

6. CONTinuous Key is below the Setup Key. This key selects the continuous mode of operation for the element selected where the instrument continuously displays (both digital and graphically) the results of successive integration over a time period specified within the mode. Burner alignment, nebulizer adjustment, HGA alignment, and gas flow adjustments can be performed in this mode.

7. DISPlay GRAPH begins the second column. Pressing this key causes the tracing of the absorbance signal being measured to be displayed on screen.

8. DISPlay CALIBration Key is below Display Graph. Pressing this key displays the calibration curve for the analysis being run.

9. DISPlay SUPPLemental Information Key is below Display Calibration. This key is used to display two types of information; the absorbance data underlying the values on the main display and the individual readings and statistics when averaging. The second use is to show the individual readings when averaging. Up to twenty readings can be shown along with the standard deviation and coefficient of variation.

10. RUN Key is below Display Supplemental Information. Pressing this key places the instrument in the Run mode where calibration and analytical work are carried out.

11. RESCALE Key begins the third column. Pressing this key allows the user to rescale the absorbance axes of peak plots, calibration plots, and flame graphics.

12. USER INDEX key is below Resale. Depression of this key calls up an index of the user's methods to the screen. Entering 2 and depressing this key calls up the second page of the index.

13. GAIN Key is below the User Index. In the Setup mode pressing GAIN initiates an automatic gain control (AGC) cycle, in which the high voltage applied to the photomultiplier tube is adjusted to provide the optimum photomultiplier output signal level, as well as an automatic intensity control.

14. STORE Key begins the fourth column. Pressing this key with a pending entry (1 to 30) stores the current method on disk at the location designated. The cookbook file references, the Programming mode entries and the calibration data are all stored. In the PROGRAM RS232C mode, this key when pressed (with no numerical entry), stores the interface conditions on the system disk. The RS232C conditions are automatically reloaded during the power-on sequence.

15. RECALL key is below Store. Pressing his key with a pending entry (1-30) recalls the designated method to the active buffer of the instrument memory.

16. PRINT SCRN (screen) Key is below Recall. Pressing this key causes the complete screen, or a portion of the screen, to be printed on a printer. The entire screen with the exception of the soft keys is printed in the Element Select, User Index, Programming, and RS232C modes. Only the center section of the screen is printed in the Run mode. In the Setup and Continuous modes, PRINT SCRN does not function.

17. PRINT Key and Indicator is below Print Screen. Pressing this key (the PRINT indicator illuminates) causes data to be printed on printer at the end of each READ cycle.

19. CE (Clear Entry) Key

20. Screen Intensity Control Knob

21. Cathode Ray Screen (CRT)

22. Eight Soft Keys

DATE/TIME -- Calls the prompt for he entry of the current date and time to set the internal clock.

DISK DUPL

PROGRAM RS232

DISPLAY -- Displays the Analytical Conditions page for the element last entered without having to re-enter the atomic number.

ENTER -- Pressing this key after keying in the atomic number of an element listed on the Element Select screen loads and then displays the Analytical Conditions for that element.

FORMAT  -- Sets up the formatting of a new user disk.

COPY  -- Duplicates both System disks and User disks. Duplicates the disk in drive "Zero" (left) onto the one in drive "One" (right).

NEW DISK -- Displays the contents of the disks currently in drive "Zero" and drive "One". Used if new disks are inserted for duplication to check that they are correct.
