Using Biomet Programs

This section describes how to select a pre-installed program and how to configure and install each sensor for each program. It also provides a basic summary of the maintenance required for each sensor, and how to retrieve the data. Refer to the sections listed below for a detailed explanation of setup for each sensor.

Biomet programs are configured to log data in a standardized format that is automatically captured by the LI-7500DS, LI-7500RS, and LI-7200RS software (version 6 and above) and embedded into .ghg files for processing in EddyPro software or the SmartFlux System.

Program Comparison

Each biomet program installed in the Sutron 9210B datalogger supports a corresponding sensor package. If you purchased a sensor package from LI-COR, this section describes how you assemble and configure the biomet station, datalogger, and sensors.

Supported Sensors

If you intend to use any of the basic sensor configurations given in Table 2‑1, simply wire the sensors to the datalogger, select the corresponding program, and enter the required sensor calibration information as described in the following pages of this section.

Table 2‑1. Sensor package components numbers and the corresponding program that supports the sensors for each Biomet program installed in the datalogger. See Installing Biomet Sensors for detailed wiring diagrams for each sensor and program.

Program Specifications

The programs are configured to sample unpowered sensors once every 5 seconds and powered sensors (the Stevens Probe and Vaisala HMP155) once every 15 seconds. Readings from each sensor are averaged over one minute and the average is logged. The power requirements of each biomet sensor package depend on the components in use. These are described below.

Sampling Frequency: One sample every five seconds for unpowered sensors; one sample every 15 seconds for powered sensors (Stevens Probe and Vaisala HMP155).

Logging Frequency: One record every minute

Power Requirements:

Biomet_100: 1.6 W Nominal (3.9 W Maximum)

Biomet_101: 1.6 W Nominal (3.9 W Maximum; 20 W Max with CNF4)

Biomet_102: 2.3 W Nominal (4.8 W Maximum)

Biomet_103: 2.3 W Nominal (4.8 W Maximum; 20 W Max. with CNF4)

Important note on Biomet Programs: Biomet programs released after May, 2014 are not compatible with biomet sensor packages that include the ML2x or with wiring diagrams for earlier Biomet sensor packages. Older programs are available from LI-COR on request.

Selecting a Biomet Program

In this section, you'll learn how to choose the program that is run by the datalogger. These steps describe how to select one of the preinstalled datalogger programs and how to choose a custom program.

  1. Connect to the Sutron (see Configuring the Biomet System).
  2. Under the Setup tab click the [+] next to Setup File, click on the Open option, and then click the Open button.
  3. Select the Program.
  4. In the subsequent dialog select from the four programs listed (BIOMET_100 to BIOMET_103). Click OK.
  5. Configure Sensors.
  6. Some sensors will require that you enter calibration coefficients before the system will log meaningful values. Click the Data tab, where you will be presented with a list of sensors that require calibration information. The contents of the data tab will vary depending upon which program you selected.

Instructions for entering calibration coefficients are given in the remainder of this chapter.
