CO2 Analyzer 2810/2815/2820 Notes: ii Instruction 19-9222
CO2 Analyzer 2810/2815/2820 1.0 INTRODUCTION 1.1 General Bacharach’s line of CO2 Analyzers are easy to use, but it is essential that these Operating Instructions be read and understood by all operators and maintenance personnel prior to using or servicing the instrument. The 2810/2815/2820 are compact and lightweight Carbon Dioxide analyzers that display the detected level of CO2 in the range of either 0–10,000 ppm (2810/2815) or 0–60% (2820).
CO2 Analyzer 2810/2815/2820 2.0 OPERATION 2.1 Important Note Always ensure that the analyzer’s gas inlet connector (Figure 1, Item C) and gas exhaust (Figure 1, Item B) are unobstructed and open to the atmosphere. Be careful not to breath directly on the analyzer while taking a measurement; otherwise, inaccurate CO2 readings will result. 2.2 Switching the Analyzer ON/OFF Switch ON the analyzer by pressing the button.
CO2 Analyzer 2810/2815/2820 2.3 Pump Operation (2815/2820) With the analyzer already switched on, momentarily pressing the button switches on the pump. Pressing the button again turns the pump off. The supplied sampling probe and hose assembly can be connected to the gas inlet connector on the top of the analyzer for drawing in gas samples from hard-to-reach locations. Particulate filter P/N 54-0548 is placed on top of the gas inlet to prevent dust or dirt from being drawn into the instrument.
CO2 Analyzer 2810/2815/2820 For those situations where water droplets may be present in the sample line, you will need to install a water trap between the Nafion tubing and the incubator’s sample port as described in Section 2.14. After completing a test, continue to run the pump while sampling fresh air until the reading is below 0.1. This will purge out any residual CO2 and moisture before proceeding to the next test. 2.
CO2 Analyzer 2810/2815/2820 2.8 Battery Charge Display The battery’s remaining charge is displayed by pressing the f2 button once. A bar graph in the lower part of this screen shows an approximation of the battery’s remaining charge. As the charge reduces, the bar graph decreases in size. Typical operating time from a full charge is 7 hours with the pump running, and 10 hours with the pump off. Battery Level = represents full charge = represents low charge 2.
CO2 Analyzer 2810/2815/2820 2.12 Powering Analyzer from Charger The analyzer can be continuously powered by its charger by connecting the charger as follows: 1. Switch ON the analyzer without the charger attached. Note: Connecting a charger to an analyzer that is switched OFF causes the analyzer to enter its charging mode, which in turn prevents the analyzer from being switched ON. 2. Plug the charger into the appropriate AC wall socket (or 12 VDC when using the optional cigarette lighter adapter).
CO2 Analyzer 2810/2815/2820 2.14 Testing Incubators (2820) When testing incubators with the Model 2820, it is important to keep moisture from entering the instrument. Moisture can contaminate the IR cell and affect the readings. A Gas Dryer Tube (Nafion) is supplied with the instrument to remove excess water vapor (humidity) – refer to Section 2.5. The Nafion tube must be used at all times when testing in high humidity environments.
CO2 Analyzer 2810/2815/2820 3.0 MAINTENANCE 3.1 Cleaning Keep the analyzer clean by wiping it with a soft cloth dampened with a mild detergent solution. 3.2 Sunlight The unit should not be left out in direct sunlight, or in other areas where excessive heat exists, for long periods since component damage due to overheating may result. 3.3 Servicing There are no user‑serviceable parts inside the analyzer. Unauthorized disassembly of the unit will invalidate the warranty. 3.
CO2 Analyzer 2810/2815/2820 Release the f2 button and follow the instructions from your local service representative. WARNING: After resetting the analyzer to its factory settings, it must be calibrated as described in Section 3.7 or erroneous gas reading may result. 3.6 Battery Charging When the ‘BattLow’ message is displayed (refer to Section 2.7), the analyzer must be recharged using the supplied battery charger.
CO2 Analyzer 2810/2815/2820 3.7 Calibration Calibration of a 2810/2815/2820 CO2 Analyzer consists of first performing either an Air Calibration on a 2810/2815 analyzer that zeros the instrument using fresh ambient air, or an N2 Calibration on a 2820 analyzer that zeros the instrument using 100% N2.
CO2 Analyzer 2810/2815/2820 2. Press and hold down the f2 button until the ‘User Cal’ screen is displayed. Note that battery status is first displayed for approximately 2 seconds. User Cal Wait until the analyzer automatically switches to its ‘Air/Gas’ screen before proceeding. f1-> Air f3-> Gas 3. Press the f1 button to zero the analyzer using fresh ambient air.
CO2 Analyzer 2810/2815/2820 3.7.1.2 Gas Calibration WARNING: This procedure assumes that you are using the Bacharach Calibration Kit as listed in Section 4.1, Calibration Accessories. When using a non Bacharach gas regulator, however, you must also use an in-line flowmeter to ensure that the gas flow to the analyzer is between 100 and 200 cc/minute. Improper flow can cause erroneous gas readings! Important! Always perform an Air Calibration first. 1.
CO2 Analyzer 2810/2815/2820 3. Using the Calibration Accessories listed in Section 4.1, attach a CO2 calibration gas cylinder to the inlet of the analyzer as shown in Figure 3. The applied CO2 concentration must equal the gas value displayed in the top line of the Gas Calibration screen. Important! Do not attempt to calibrate the analyzer if the pressure gauge closest to the tank reads below 5 psi. 4.
CO2 Analyzer 2810/2815/2820 3.7.2 2820 Calibration Procedure 3.7.2.1 N2 Calibration The following procedure uses 100% N2 to zero the analyzer. (Fresh ambient air that is assumed to contain 340 ppm CO2 can be used if N2 is not available.) Important! DO NOT perform an N2 calibration after sampling high concentrations of CO2 gas. Also, be careful that your breath does not affect this procedure. 1. Switch ON the analyzer.
CO2 Analyzer 2810/2815/2820 4. Press the f1 button to zero the analyzer using 100% N2 or fresh air. If the N2 Zero procedure was successful, the display will show N2 Cal OK If the procedure was unsuccessful, the message N2 Cal Failed will be displayed. If this happens, retry the N2 Zero procedure, ensuring that the analyzer is only exposed to either 100% N2 or fresh air. If the procedure is still unsuccessful, then the analyzer must be returned to a Bacharach Service Center for evaluation. 5.
CO2 Analyzer 2810/2815/2820 Wait until the analyzer automatically switches to its ‘N2/Gas’ screen before proceeding. f1-> N2 f3-> Gas 3. Press the f3 button to display the Gas Calibration screen. f1->05.0 00.0 The top line shows the preset calibration gas value that must be applied to the analyzer’s inlet. The bottom line shows the current CO2 reading. Note: The analyzer is most accurate around the calibration gas value.
CO2 Analyzer 2810/2815/2820 6. Allow the calibration gas to flow until the second line of the Gas Calibration screen stabilizes, then press the f1 button. If the gas calibration procedure was successful, the display will show GasCal OK If the procedure was unsuccessful, the message GasCal Failed will be displayed. If this happens, retry the Gas Calibration procedure, ensuring that the analyzer is exposed to the correct concentration of calibration gas.
