    C source. All C issues will be handled by the manufacturer either under warrantee or at ADEC cost. When working close to the beta source for any length of time, the wearing of long sleeves and laboratory gloves may help reduce possible exposure to C beta rays.
  • Page 6: Installation Procedure

    To date, all ADEC purchased BAM-1020 monitors currently include or are in the process of being upgraded with an inlet heater kit. This heater kit is crucial for most applications throughout the State of Alaska. When the BAM-1020 internal relative humidity sensor detects inlet moisture content >...
  • Page 7: Physical Inspection

    The BAM-1020 was designed to operate in a temperature-controlled enclosure between 0 °C and 40 °C, and where the relative humidity is not condensing and does not exceed 90%. All ADEC BAM-1020 monitors will be deployed inside a weather-proof and temperature controlled structure.
  • Page 8: Installing Bam-1020 Central Unit

    4. Heater Kit: The inlet heater kit includes a heater block that slides over the lower end of the inlet tube (inside the station). When installed, the heater will cover approximately four (4) inches in length of the inlet tube. The installed heater should be a minimum of two (2) inches away from any object at either end of the heater, such as the instrument rack or ceiling.

    hole saw until the hole is deep enough to accommodate the roof mounting plate. Attaching Inlet Support Hardware: Affix the inlet mounting plate to the top of the roof with plenty of weatherproof sealant and four adequate lag bolts. Attach the supplied inlet coupler to the mounting plate. Slide the inlet tube through the coupler, plate, roof and ceiling.

    Outside Temperature (OT) Connection: All ADEC deployed BAM-1020 monitors will be configured for volumetric flow control. This will require the installation of the supplied OT sensor. The BAM-1020 OT sensor must be calibrated prior to the BAM-1020 monitor flow calibration.
  • Page 11 due to a configuration parameter that is out of the BAM-1020 operating range or a value that is significantly different than the current operating conditions. When configuring or calibrating the BAM-1020, it is important to exit out to the main menu before proceeding to the next parameter.
  • Page 12: Start Sampling

    BAM-1020 monitors purchased by the ADEC have been configured for 'VOLUMETRIC’ flow control. To check the BAM-1020 for correct 'VOLUMETRIC’ flow control configuration: 1. Press the "SETUP" soft key. 2. Use the arrow keys to move the cursor over the word 'Calibrate' and press "SELECT".
  • Page 13: Weekly Checks

    Weekly Checks Check the BAM-1020 filter tape. One roll of filter tape should last approximately 2 months. Replace when necessary. Biweekly Checks Download data records and error records directly from the BAM. This data should be used to verify the data collection via modem or other communications methods. Note: This may need to be done on a more frequent basis.

  • Page 16: Maintenance Procedures

    MAINTENANCE PROCEDURES General Information Normal BAM-1020 maintenance requires keeping the BAM-1020 central unit dust free and all sampler inlets clean. Sampler Maintenance As with all monitoring equipment, the BAM-1020 should be kept clean and dust free. Use a lint free cloth to remove dust. Remove all inlet filter screens and wash with soap and water. Sharp Cut Cyclone (SCC) Maintenance The PM SCC inlet requires removal from the inlet tube, disassembly and cleaning.

    Connect the computer port cable to the upper RS232 connector located at the rear of the BAM- 1020. Activate the HyperTerminal program and press the computer's return button three times. An asterisk (*) should appear. If not, depress the small white and red polarity toggle switch located next to the RS232 connector on the back of the BAM-1020.
  • Page 18: Perform Operational Checks

    If the BAM analog outputs are going to be used to perform the following tests, connect a strip chart recorder to the instrument analog output so that variations may be monitored and evaluated. Recorder charts should be cut into 24-hour segments and labeled at the bottom with the following: 1.

    1020 (BAM-1020) verification and calibration procedures used by ADEC. The Met One Instrument's BAM-1020 Operation Manual is an important resource of information for BAM- 1020 calibrations, and therefore the ADEC highly recommends a thorough review of the BAM- 1020 Operation Manual.
  • Page 20: General Information

    5. Calibration forms or laptop computer 9.1.4 General Information The calibration of the Met-One BAM Monitor should be performed in the following steps: 1. Ambient temperature sensor calibration/verification. 2. Ambient pressure sensor calibration/verification. 3. Volumetric flow calibration/verification. Record all calibration information and data. It is important to exit back to the main menu between each complete calibration parameter.

    6. Confirm OT calibration by performing steps 1 through 3. 9.2.4 Barometric Pressure Sensor Calibration: The BAM-1020 internal barometric pressure sensor is calibrated by initiating the BAM-1020 barometric sensor calibration sequence and entering in a single ambient pressure value. Perform the following steps to calibrate the BAM-1020 barometric pressure sensor: 1.

    Tech Note # 1 Removing BAM from shelter. Met One BAM 1020 Removal for Maintenance Procedures The following is a guide that describes the steps required to perform maintenance on the BAM 1020 sampler if access to the internal components is necessary. This guide describes the steps necessary for a BAM sampler that is located inside of a small enclosure.
  • Page 32 Step 10. Remove the flat head screws located on the front side of the BAM. Step 11. Remove the BAM from the shelter. Step 12. Remove all of the cross tip screws that hold the cover on the BAM Note 1: The BAM sampler should not be open to environmental conditions that may cause damage to the internal components.
