Appendix A. EC150 Settings

A.2.12 Heater Control

When set to automatic, this setting applies a voltage between 0 and 4600 mV to

heaters near the optical windows of the analyzer. Heated windows inhibit the

formation of condensation, such as dew and frost, and help the analyzer

recover more quickly when precipitation has blocked the optical path.

The

Heater Control setting is stored in non-volatile memory in the EC150

head.

A.2.13 Head Power Off

When enabled, the EC150 gas head is turned off. The head may be turn on/off

under datalogger control to conserve power or under EC100 control if the gas

head temperature is outside the operating range. The EC100Configure()

Instructions in the CRBasic program is used to turn the gas head on/off under

datalogger control.

The

Head Power Off setting is stored in non-volatile memory of the EC100.

A.3 ECMon

Settings for the EC150 are easily verified and/or changed by using the

Windows PC support software ECMon (ECMon is short for Eddy Covariance

Monitor), which is found on the EC150 & EC155 Support CD (pn 27007) or at

www.campbellsci.com/downloads

.

Before installing ECMon, read the file named Read.me.text found on the

EC150 & EC155 Support CD. This will direct the user to install USB drivers

(also found on the Support CD) which are required for communications

between the PC and the EC100 via the EC100 USB cable (pn 26563). Some

newer PC operating systems will automatically find and download the USB

drivers from the internet when the USB cable is connected to the PC.

Once the drivers are installed, download and run the ECMon.exe install file.

Launch ECMon and connect the EC100 electronics to the PC with the included

EC100 USB cable (pn 26563). The USB connection for the EC100 electronics

is found on the bottom of the enclosure (see FIGURE 6-12). Once connected,

select the appropriate communications port in the ECMon Main Page and click

Connect (see FIGURE A-4). Next click on the Setup button. All of the above

settings are now available for the user to change (see FIGURE A-5).

Besides changing settings, ECMon is also a useful tool for other common tasks

such as:

Monitoring real-time data from the EC150 using the Main window

Performing a manual zero and span of the instrument (see Section 7, Zero

and Span)

Troubleshooting and monitoring diagnostics using the Status window
