Page 11: Setup
CO2/CH4 Sampling Data Logger User’s Manual NOTE: Refer to the GasLab User’s Manual for more information. ® The sampling meters will require minimal setup since they are designed to be portable. The most Setup important aspect of the setup involves connecting the sampling hoses and ensuring proper setup. The Instrument Overview section on page 8 shows the labeled components of these meters, as referenced throughout the rest of this manual. Insert four (4) AA size batteries into these units or connect them to the included power supply. All models have an internal coin cell CR‐2032 3V battery backup for the real‐time clock. This battery is inserted in the factory for your convenience and should last the lifetime of the product. Sampling Data Logging Besides including all the features of our sample draw model above, this model also features an internal memory capable of storing data when not connected to a computer. This unit will allow you to simultaneously read and store CO2/CH4 concentration levels data. Due to the nature of their design, this unit should be connected to your computer first, before operation, in order to initialize and set the logging interval and real‐time clock. In order to initialize data logging functionality, the unit MUST be connected to the computer with data logging switched to OFF, and the GasLab software started. Once the unit has been connected, ® click on the “Configure Sensor” button in the GasLab interface, set the data logging interval and ® pump periods as desired. We recommend leaving the pump interval to the default 5‐second period. For the pump period, we recommend 5 or more seconds. The pump PWM period can also be adjusted for advanced applications, with 1 being full duty cycle, and values approaching 255 being the shortest duty cycle. The pump mode should always be set to “Data logging” for proper operation of the unit.
