1. Monitor Components 1.1. Series 200 and 300 Monitors The following components are supplied with the Series 200 and 300 Monitor: Monitor base Sensor head 12 VDC AC/DC adaptor or Lithium Smart Charger Battery pack – 9.6V Ni-MH or 11.1V Lithium Polymer Optional – Temperature and relative humidity sensor 1.2.
2. Installation The following actions need to be completed before the monitor is ready for use: Insert the sensor head into the top of the monitor. The sensor head is keyed to ensure the head is inserted correctly. The battery must be connected and charged prior to use. The battery is shipped installed in the monitor but disconnected. The temperature and RH sensor needs to be inserted – optional 2.1. Battery Pack 2.1.1. Installation 1.
With the adaptor plugged in and unit turned on allow 15 hours for the battery to fully charge. During charging the battery symbol on the display flashes slowly The battery can be charged with the sensor head installed or removed from the base.
2.2. Sensor Heads Outlet Inlet (meshed) Keyed connector to ensure inserted correctly into base Note: Always place the sensor head perpendicular to the air flow to avoid damage to the sensor 2.2.1. Sensor Warm Up Prior to operation the sensor must be warmed up to burn off any contaminants. When the monitor is first switched on it will warm up for 3 minutes. The reading will then flash for the next 7 minutes to indicate that the sensor is still in the warm up phase.
2.3. Optional Temperature and Relative Humidity Sensor If the temperature and relative humidity sensor has been purchased, it can be inserted into the PS/2 connector at the base of the monitor. Ensure monitor is turned off before connecting the sensor. Two Way Adaptor Cable Temperature & Relative Humidity Sensor USB to Monitor Cable Note: The monitor will still operate with only the temperature and RH sensor connected. 3.

Click the save button to synchronise the monitor values with those on the PC.
If for any reason, the data download does not complete, is terminated or stops: Turn off the monitor to prevent any data loss. Delete the data that has been downloaded to the PC Close the PC software program and repeat the downloading process with the monitor on, connected and with the PC software running. 4.2.3. Graphs While logging directly to a PC, the Real Time View Graph or the Logged Data Graph can be accessed via the “Data” menu on the menu bar.
In the logged data table view the date, time and sensor type can be selected to view the relevant data. The Monitor and Location ID can also be selected. Once these parameters have been selected click “apply” to filter the data and display the selected parameters. Note 1: The logged data table will display up to 7 days of data on each page. Click the arrows at the bottom of the table to view the previous or next 7 days of data within the filtered data set.
4.3. Database Management 4.3.1. Exporting data To export the database click File Export Logged Data The table above will appear. The database can be filtered using the date, time, monitor ID, location ID and sensor type parameters to select the exact set of data to be exported. Click export, select a directory, choose a file format (either plain text or MS Excel file) and enter a file name. Click “Save” to export the data to the chosen location. Note 1: Only one monitor ID can be exported at a time.
2. To view archived logged data, Click File Database management Unzip Database Select the zipped file and click OK. View and analyse data as required (Data Table Logged) Note: To view an archived database it is important that any existing data logging function is not interrupted. Do not view archived data on the same PC being used for data logging; the current data in the database will be lost unless it has been zipped. 5.
5.2. Wiring for Control The control pin can be wired to supply control of a gas concentration between upper and lower concentration limits. The upper and lower limits can be set by the user. The factory default settings are dependent on the gas sensor head selected at time of purchase. To switch to GND use pins 3 and 6. For a 12V output wire to pins 3 and 1 (see following diagram for typical wiring). This feature will only operate while powered by the AC adaptor.
6. Calibration of Sensor Heads Sensor heads can be calibrated in two ways: 1. Via replacement. Return your sensor head to Aeroqual and purchase a replacement sensor with a multi-point calibration and new calibration certificate. 2. Manual calibration. The easy calibration procedure is outlined below. Aeroqual supplies a Calibration Accessory (R42) to facilitate humidity control and delivery of calibration gas to the sensor head. 6.1.
2 1 6.2. 3 Zero Calibration Under some circumstances the sensors may temporarily exhibit a baseline reading higher than zero due to insufficient warm up or cross-sensitivity to other gases. In this case it is also worthwhile checking against a standard zero air source. 1. Follow the initial set up instructions in 6.1 2. Flow zero air until the reading stabilises (about 10 minutes) 3.
For the majority of uses, gases will be purchased for calibration at the concentration to be used for the span calibration, rather than purchased at high concentrations and later diluted using a gas dilution calibrator. Therefore users may find some restrictions on what concentrations can be provided by their chosen calibration gas supplier. For some applications measurements will be made close to the monitor’s maximum detection limit. For these applications a span point at 80 % of full scale is suggested.
6.3.1. Procedure 1. Follow the initial set up instructions in section 6.1 2. Flow the target gas at 0.5 LPM 3. Measure the gas concentration on the monitor screen and wait for it to stabilise (10 minutes). 4. If the Aeroqual sensor head requires a span adjustment then enter the CALIBRATE menu by pressing the “mute” and “scroll down” buttons simultaneously for 2 seconds. Then select SPAN CAL and change the GAIN using the scroll buttons.
The United States Department of Labour http://www.osha.gov/SLTC/compressedgasequipment/index.html The following information is a guide for what to consider when handling compressed gas but Aeroqual recommends operators adhere to their local regulations regarding compressed gas handling. 6.5.1. High pressure leak or failure of pressure regulator Many calibration gases are held in cylinders at high pressure in excess of 1000 Psi.
handled as such. Health and safety data are often revised, Aeroqual recommends checking external sources for the most up to date information. Aeroqual suggests that all span calibrations be performed in a fume hood such as the one in the image below to avoid exposure to personal.
7. Specifications The Aeroqual handheld monitors have been specifically designed to incorporate Aeroqual’s in-depth knowledge of accurate ambient gas measurement and can be used with a wide range of gas sensor heads. The sensor heads are interchangeable and therefore multiple heads can be used on the same base unit. The sensors are calibrated prior to delivery.
7.1. Diagrams Page | 28 MRK-D-0022 V3.
7.2. Optional Extra: Handheld Enclosure The handheld FRP enclosure is designed for fixed or secure monitoring. The inlet nozzles are specifically designed to eliminate dust and reduce water ingress whilst minimising destruction of part per billion gas concentrations or measurement variations due to outgas contamination from the enclosure. The sensor heads are specifically calibrated to take into account the longer flow path.
7.2.2. Replacing the Sensor Head 1. Undo the four lid screws at each corner using a flat headed screw driver and remove the lid. 2. Unscrew and remove the inlet and outlet nozzles and threaded lock nuts on either end. 3. Remove the sensor head by carefully pulling it upwards, disconnecting it from the monitor. 4. Replace the sensor head. 5. Re-insert the nozzles and tighten using the lock-nuts on either end and ensure there is a tight fit against the sensor head. 6.

9. Guidelines on How to Measure Ozone The following information is presented to help users operate their Aeroqual monitor with an ozone sensor installed in the most effective and efficient manner. General Ozone is heavier than air and tends to sink. Thus detection of leaks from ozone generating equipment should be performed at the most appropriate position. Ozone will react and decompose on surfaces such as walls, furniture etc.
10. Care and Maintenance Your Aeroqual Monitor is a product of superior design and quality and should be treated with care. When using your Aeroqual Monitor: Keep it and all its parts and accessories out of the reach of small children. Keep it dry.
