Notes: 1. The anemometer is to be mounted separate to a pole. Could be same pole as sensor. 2. Battery backup time depends on run mode and frequency of transmission. 3. Requires SIM card and suitable data plan on AT&T or T‐mobile 4. Cloud based analytics can be developed with additional contract 5. When removing SD card to obtain data, it is recommended to power off the sensor box prior to reinserting the SD card to avoid possible errors. If the system stops responding after inserting an SD card, power down the sensor and turn back on. ...

Notes: 1. If the unit has been off for an extended period of time, it will take approximately 12‐24 hours for the electrochemical sensors to stabilize completely. 2. There are additional CO sensors available with identical form factors if higher concentrations (e.g. 10,000 ppm) are determined to be necessary. 3. The anemometer that is designed to work with the RAMP is the Davis Vantage Pro 2 Anemometer (https://www.davisinstruments.com/product/anemometer‐for‐vantage‐ pro2‐vantage‐pro/) ...

Quick Start Deployment Guide It is recommend to use a computer and the supplied USB cable when setting up the sensor unit to verify the operation of the sensors, system output, and cellular data connectivity (if applicable). 1) Unpack the sensor unit and check for any physical damage or obstructions at the sensor openings. Open enclosure cover and check for any loose or damaged components. Make sure all wires are securely fastened. 2) Hook up USB cable sensor and initialize terminal connection. Power on unit and verify that the SD card was detected and initialized. 3) Enter into USB mode from startup or from configuration menu. Verify the sensor outputs are reasonable or trending toward reasonable values keeping in mind the stabilization time for the electrochemical sensors. The output format is shown below: Heading Description Units/Format DATE Local Date and Time MM/DD/YY HH:MM:SS (24H) CO CO PPB NO/SO PPB NO/SO2 NO2 NO PPB 2 ...

Failure to do this will result in arbitrary wind direction. 6) After verifying functionality remove the USB cable. If planning to run in USB mode, install a power adapter or a solar panel for long term deployment applications. Otherwise, power cycle the RAMP, then install a power adapter or a solar panel for long term deployment applications. Notes: 1. Position 2 is designated for either an NO or SO electrochemical sensor 2. The Heading for the ports will be specific to the device that is connected not ‘Port #’ ...

‐ Sensor ‐ USB data cable ‐ Computer with a serial port terminal software program (e.g. CoolTerm) Sensor Quickstart Instructions 1) Connect the USB cable to the RAMP and computer and establish the communication link in the terminal software. 2) Turn on power switch and observe initialization process. After initializing the microcontroller and printing RAMP information, the system will system will prompt the user to: “Enter Configuration Mode? (YES)” or “Enter Calibration (USB) Mode? (CAL)” 3) Configuration mode allows access to configuration settings and system settings. To enter configuration mode type Yes at the prompt and hit enter. ...

, PM2.5 reading. Calibration mode is temporary and will be lost upon a system power cycle. To enter calibration mode type Cal at the prompt. ‐ To set new zero level expose the sensor to zero air and type the following: CO:zero, NO:zero, NO2:zero, O3:zero, CO2:zero, or PM25:zero ‐ To calibrate the sensor to a known level of target gas replace ‘zero’ with the actual ppb reading for CO, the actual ppm reading for CO , or the g / m reading for PM2.5 (e.g. CO:10000 would calibrate to 10000 ppb CO, CO2:1500 would calibrate 1500 ppm CO , or PM25:20 would calibrate 20 g / m ) Note: Please allow 1‐2 outputs for the sensor reading to update. ...
