Push INT button (interval) to cycle through the choices for how often to 5.

log a data point. Stop when the desired interval is displayed. Notice how

much time can be covered with the remaining free memory.

Push and hold the START button until the screen goes blank (two seconds) 6.

to begin a new data logging session. The unit will now display the gas

concentration. The Lg symbol in the left side of the display indicates that

the unit is logging data. If you watch this symbol carefully, you will see it

change to an “s” each time a data point is stored.

Working with the “EC-P2” program:

The “EC-P2” program downloads the logging ﬁles from the Honeywell 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 Honeywell EC-P2 and connect it to your PC using the RS-232 cable

supplied. From Windows START menu, select “PROGRAMS,” then “Honeywell 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 Honeywell EC-P2. If the Honeywell 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 Honeywell EC-P2.

When you are ready to transfer data from the Honeywell 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.

4.5 Analog Output

The Honeywell 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.
