Press “KEY 4 START/STOP LOGGING” to start and stop data logging. While in data logging mode, the instrument will automatically record data at the pre-set intervals including running the pump for a preset time period. Active logging mode is indicated on the “MAIN READ SCREEN” by its icon.
CO2 Analyzers 3100 & 3150 5.9.2.7 Reset The instrument can be reset by pressing “KEY 7 - RESET” accessed via the “UTILITIES” menu. Selecting this option will clear all user settings and any stored data including the event log. A confirmation code (12345678) must be entered to confirm that a reset is initiated. 5.9.3 Calibration The instrument is fully calibrated during manufacture and when returned for service. However, to improve accuracy between services, a user/field calibration can be performed.
CO2 Analyzers 3100 & 3150 4) Press the soft-key “MORE” to refine or filter the readings to view. Setting Use 1 Delete All Enables the operator to delete all the readings stored, (see below). 2 Filter Used to refine/filter the range of readings displayed by ID or date ranges.

Typically, a fully charged battery will last 8-10 hours.
CO2 Analyzers 3100 & 3150 6.0 Taking Readings 6.1 Preliminary Checks - Best Practice Prior to use, it is good practice to ensure that: Step 1 The instrument has the correct time and date set. Step 2 The sample filter is fitted and that it is clean and dry. Step 3 The battery has a good charge (minimum 25% charge, even if only a few readings are required). Step 4 The memory has sufficient space available. Step 5 The main gases have been auto-zeroed, without gas concentration present.
CO2 Analyzers 3100 & 3150 3) Connect the sample tube, if relevent (always use the sample filter) from the sample point to the inlet port of the instrument, ensuring that the filter is seated correctly. 4) Press the “PUMP” key to draw a sample into the instrument. Notice the main gas readings start to change. It is recommended to run the pump until the gas readings have stabilized (approximately 30 seconds) then press the soft-key “STORE” if desired.
CO2 Analyzers 3100 & 3150 6.3 Alternative Reading Methods There are three other reading types or methods which each require slightly different operating procedures. • Logged reading • Peak reading • Hold reading 6.3.1 Logged Reading Logged readings need to be configured and initiated via the “UTILITIES” menu by pressing “KEY 6.” During configuration, the user will be asked to supply an ID, reading interval, and pump run-time. These parameters are used to control the reading frequency in logging mode.
CO2 Analyzers 3100 & 3150 7.0 Calibration 7.1 User Calibration The instrument is fully calibrated during manufacture and when returned for service. However, to improve accuracy between services, a user / field calibration can be performed. User calibration is a means of optimizing the performance of the instrument to the current operating conditions, such as ambient temperature and pressure, as well as correcting for instrument drift caused by lamp and filter settling.
CO2 Analyzers 3100 & 3150 7.2 Calibration Gases User calibration of the instrument will improve the data accuracy in the range of the calibrated gases used. However, it may cause less accurate readings of concentrations outside this calibrated range. Users should select the correct calibration gas for the expected gas levels on their particular application. Only use gases with a known certified gas concentration. NOTE: Certified calibration gases can be supplied by Bacharach.
CO2 Analyzers 3100 & 3150 7.4 Calibration Equipment The diagram below displays the regulator and tubing equipment for user calibration: Calibration Kits are available through Bacharach Inc. Calibration Kit: P/N 19-8027 Cylinder of N2 Gas: P/N 23-4003 Cylinder of 5% CO2 Gas: P/N 24-1126 (Model 3100) Cylinder of 2500 ppm CO2 Gas: P/N 24-1130 ( Model 3150) • Contact your nearest Bacharach Service Center for further information.
CO2 Analyzers 3100 & 3150 7.5 Calibration Method Before you begin, ensure that the unit is stabilized at its working temperature before performing any of the calibration operations. To achieve the processes set out in this section, press “KEY 3 CALIBRATION” from the “MAIN” menu. The first screen displayed provides the option to select the gas that requires calibration. The exact calibration method can vary depending on the gases used. 7.5.
CO2 Analyzers 3100 & 3150 2) Press either “KEY 1 - ZERO WITH N2” (recommended) or “KEY 2 ZERO WITH AIR” from the menu. Then, either attach the 100% N2 or sample pipe to allow access to fresh air. 3) Press the “START” key. The instrument will now wait approximately 60 seconds for the gas reading to stabilize at the correct level. Ensure the pump is on (pump icon appears in lower middle of screen when on). 4) The instrument will then indicate a successful zero has been completed.
CO2 Analyzers 3100 & 3150 3) Once a stable reading is shown, press the soft-key “ACCEPT.” A successful span calibration message will then be displayed. Press the soft-key “ACCEPT” again to confirm the calibration and “STORE” the new user span. Alternatively, press soft-key “REJECT” to exit without change. NOTE: If the calibration failed then try again using a longer purge time or different target gas. 7.5.3 Zero O2 Channel It is not necessary to zero the O2 channel.
CO2 Analyzers 3100 & 3150 7.5.5 Reset Factory Settings This option will reset the instrument to its factory programmed calibration characteristics and will clear the user calibration points for both gas channels. 1) To reset to factory settings, press “KEY 1 - FACTORY RESET” from the “CALIBRATION” menu. 2) To prevent the user calibration data being accidently erased the user must confirm the action by pressing the soft-key “ACCEPT” or soft-key “REJECT” to exit without change. 7.

CO2 Analyzers 3100 & 3150 8.0 Problem Solving This section outlines various warning and error messages which the operator may receive during general operation of the instrument. For further assistance please contact your nearest Bacharach Service Center. 8.1 Warnings and Errors When switched on, the instrument will perform a predetermined self-test sequence taking approximately 60 seconds. During this time many of the instrument’s working parameters and settings are checked.
CO2 Analyzers 3100 & 3150 Under and Over Range Codes If a reading is over range (i.e. above the maximum allowed reading) it will be displayed with ‘more than’ chevrons (>>.>). This can occur if a channel has been incorrectly calibrated or the sample gas has exceeded its specified range (e.g. CO2 >20%). If a reading is under range (i.e. below zero) it will be displayed with ‘less than’ chevrons (<<.<). Refer to Section 7.0 Calibration to remedy under-range by performing a user zero.
CO2 Analyzers 3100 & 3150 Check CO2 Cal. This warning is most commonly caused by an incorrect user calibration. Try recalibrating the sensor or press “RETURN TO FACTORY SETTINGS.” If the warning persists it may be caused by dirt or damage to the infrared sensor. The instrument will need to be returned to your nearest Bacharach Service Center for service / repair. Check O2 Cal. This warning is most commonly caused by an incorrect user calibration.
CO2 Analyzers 3100 & 3150 8.3 User Calibration Trouble Shooting Error Remedy User Zero Failed A possible reason for this is because the instrument is trying to zero to a level which is outside the predetermined range set when the unit was calibrated at the factory. To rectify this, first ensure the unit contains absolutely none of the gas which is being zeroed by flushing thoroughly with nitrogen. If it will not zero, then refer to the instructions given in the “FACTORY SETTINGS” section.
CO2 Analyzers 3100 & 3150 9.0 Service The instrument should be regularly serviced to ensure correct operation and accurate readings. Bacharach recommends a full service and factory calibration every 12 months. Depending on usage, the O2 cell should be replaced every 2-3 years. User Serviceable Parts NOTE: There are no user serviceable parts inside of the instrument. Please do not attempt any repair as this may void the warranty.
CO2 Analyzers 3100 & 3150 10.0 Warranty Policy This instrument is guaranteed, to the original end user purchaser, against defect in materials and workmanship for a period of 12 months from the date of the shipment. This period covers repair or replacement of defective parts on an exchange basis. The decision to repair or replace will be determined by Bacharach Inc. To maintain this warranty, the purchaser must perform maintenance and calibration as prescribed in the operating manual.
