To Stop the Data Logging Session

7)Push the MENU button.

8)Push the LOG button.

9)Push and hold the STOP button until the screen changes to CLEAR / INT / START / MODE (two seconds).

10)Push the DONE button to get back into normal operation mode.

EAnalog Output

The Manning EC-P2 has a 0 to 1.0 volt DC analog output capability when used with the optional analog output cable. With the analog output cable plugged into the communication port of the EC-P2, the user can measure the voltage between the two wires and correlate it to gas concentration. The voltage output will be linear between zero and the full scale range of the SMART-CELL as programmed below. Each SMART- CELL has a wide range of choices of full scale values.

Working with the “EC-P2” program:

The “EC-P2” program downloads the logging files from the Manning EC-P2. It does not display the data. The files it downloads can be opened by or imported into Excel, Lotus 123 or other programs for graphing and analysis.

Turn on the Manning EC-P2 and connect it to your PC using the RS-232 cable supplied. From Windows START menu, select “PROGRAMS,” then “Manning EC-P2,” and then “EC-P2”. As soon as you start the “EC-P2” program, your computer will try to establish a connection to the Manning EC-P2. If the Manning EC-P2 is currently logging data, the “EC-P2” program will automatically stop the logging function.

The program contains two tabs, one marked “Download” and one marked “Configure”. Review the settings on the “Configure” tab, making changes as necessary.

From the “Download” tab, review the Link Status block in the lower right hand corner. It should indicate “Link OK”. Link Trouble can be caused by selection of the wrong Com port in the Configure Tab, improperly connecting the RS-232 cable, or not turning on the Manning EC-P2.

When you are ready to transfer data from the Manning EC-P2 to your PC, click on “get data” and the files will be downloaded to your computer. Note the file names in the destination window so you can locate the files.

These files can now be opened with Excel (use .csv filename), Lotus 123, or other user supplied programs.

The full scale range as programmed below only affects the analog output and the

data logging full-scale output. The display will always cover the entire operating range of the SMART-CELL. Changing the range can affect the display resolution for some SMART-CELLs.

Changing the full scale range on EC-P2:

To Enter RANGE Mode

1)Push power button to turn unit on. Wait for power up sequence to finish (30 seconds).

2)Push and hold the unnamed button (second from left) first, then Push and hold the MENU button. Hold both buttons until the screen goes blank (two seconds). Release both buttons and the unit is now in Programming Mode.

3)Push the MORE button.

4)Push the DISP (display) button.

5)Push the MORE button and the unit is now in the RANGE mode.

Adjusting the RANGE

6)Push RANGE button.

7)Push INC button (increase) or DEC button (decrease) until the display matches the desired full scale range.

8)Push SAVE button to store new full scale range.

To Exit RANGE Mode

9)Push DONE button twice slowly to get back into normal operation mode.
