Page 10: Setup
Sampling Data Logger User’s Manual 1. Turn the meter ON. 2. The meter must be started at least 1 minute prior to deployment and data logging to allow the CO2 sensor time to warm‐up and calibrate. 3. Set the logging interval as desired and commence logging by depressing the “Log” button on the right side of the meter. 4. When data logging is completed, turn the “Log” OFF. NOTE: Refer to the GasLab User’s Manual for more information. ® Setup CO2Meter, Inc.’s sampling meters will require minimal setup since they are designed to be portable. The most 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. Data Logger Models These models feature an internal memory capable of storing data when not connected to a computer. These units will allow you to simultaneously read and store CO2 concentration level data. Due to the nature of their design, these units should be connected to your computer first, before operation, in order to initialize and set the logging interval and real‐time clock. Insert four (4) AA size batteries into this unit or connect the unit to the included power supply. 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 10‐second period. For the pump period, we recommend 10 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. 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.

Turn the meter ON by pressing the power switch once. 4. Turn logging ON by pressing the LOG switch once. Once the sampling process is completed, data can be downloaded to your computer using our GasLab software. ® Calibration All units are factory‐calibrated with multiple reference points of gas, and have been verified to be accurate within their specific functionality before shipment. However, if the unit is severely jolted or otherwise mechanically disturbed, the sensor can drift requiring recalibration. All calibration procedures follow a single‐point calibration routine that effectively shifts the zero‐point of the CO2 sensor. Supply calibration gas to the unit and connect the unit to a personal computer. Open the calibration screen in the GasLab software. Click the CALIBRATE button in the calibration tab for the desired gas, located in the ® CONFIGURE SENSOR screen. As long as the gas concentration is stable, the unit should instantly reflect the calibrated value. This can be confirmed by watching the display. To see the calibration value in real time, click in the COLLECT REAL‐ TIME button to capture these values before opening the configuration screen. PAGE 12 of 17... -
Page 13: Calibration Procedure
Sampling Data Logger User’s Manual 1% or 30% Sampling Data Logger Calibration can be performed using either 100% CO2 calibration gas (typically nitrogen, argon, etc.), or using a fresh source of air, assumed to be approximately 400ppm. NOTE: Refer to the GasLab User’s Manual for complete instructions. ® Calibration Procedure To calibrate your meter, follow these steps: 1. Turn ON the meter. 2. Expose the meter to ambient air (assumed to be at 400ppm) or supply calibration gas bottle/cylinder (100% nitrogen or argon) with the appropriate demand regulator. 3. Wait 25 seconds to collect a sample. Write down this value as the “before” value. 4. Click the CALIBRATE button after selecting your calibration gas. 5. Wait 25 seconds again. This time, the meter will take a sample and use this data to adjust zero values. The displayed measurement will show the new calibration value (0 or 400ppm, depending on method used). 6. Disconnect the Calibration gas and wait 25 seconds. All displayed data will now be based on the new calibration value. Repeat this procedure if the sensor is still operating outside of its specified range or if readings vary greatly. 5%, 60%, and 100% Sampling Data Logger These models do not feature Automatic Background Calibration (ABC) algorithm due to the CO2 scale they measure. To ensure the highest accuracy, we recommend calibrating these units with calibration gas (Nitrogen for ZERO or CO2), close to the concentration being measured. Alternatively, a 100% or ambient calibration can be performed. To perform a calibration, attach the unit to your computer, power it with the wall adapter and either expose it to atmosphere or supply it with your calibration gas, fed with a demand‐based regulator. Open the GasLab software on your personal computer and click the CONFIGURE SENSOR button. Cick the TURN ® PUMP ON CONTINUOUSLY button to ensure continuous flow. (To apply any changes, the meter has to be restarted). Zero or Fresh Air Calibration Supply gas and select the appropriate concentration in the screen. Click the CALIBRATE button. The sensor reading should instantly reflect the calibration. High‐Concentration Calibration Write down the original Zero Value before adjustment for future reference. Apply the desired concentration calibration gas; adjust the Zero Value in increments of 10 pressing the large SAVE button on the right until the unit... -
