This video will guide you through the correct procedure for measuring the color of roofing granules using the HunterLab Aeros Spectrophotometer.\nBefore we begin, safety is the top priority. Be sure to follow your safety procedures and wear the required personal protection equipment while performing this procedure in the lab.\n\nDaily Standardization\n\nTo ensure accuracy, the spectrophotometer must be standardized at least once every 24 hours. The software will prompt you if it's required.\nBegin by launching the EasyMatch QC software from the desktop. To start standardization, click the 'Standardize' button.\nFollow the on-screen prompts. First, the software will ask to move the sensor to the top position. Click Next. Now, locate the magnetic standardization box. Attach the box to the sensor head, then attach the black glass to the box, making sure the lines are aligned. Click Next. When prompted, remove the black glass and attach the white standard tile, again aligning the lines. Click Next. Next, When prompted, remove the white standard tile and attach the green tile again aligning the lines. Click Next. Once you see the \"Standardization is completed\" message, click Finish and remove the standardization box. If you get a \"FAIL\" message, clean the tiles and repeat the process.\n\nWeekly Green Tile Diagnostic Check\nAt least once per week, a green tile diagnostic check must be performed to verify the instrument's performance. In the top menu, navigate to Sensor, then Diagnostics, and select 'Green Tile Test'. Follow the prompts, which will first guide you through the same black and white tile standardization we just performed. After standardization, the software will ask for the green tile. Place the green check tile under the sensor port and press OK.\nA PDF report will be generated showing a PASS or FAIL result. Save this report using the default file name.\n\nSample Preparation and Measurement\nNow, let's measure a sample. It's critical that your granule sample is representative of the product and is at room temperature before reading.\nPour the granules into the sample tray, slightly overfilling it.\nNext, use a tool with a straight edge to level the granules. Scrape off the excess material, creating a smooth, flat, and even surface. The granules should completely level the bottom of the tray.\nPlace the tray onto the instrument's turntable, aligning it with the spindle.\n\nEnsure that the horizon arm indication is at 2.5 on the side scale.\nIn the software, click the 'Read Sample' button or press the F3 key. You may be prompted to enter a Sample ID or other information.\nPress Enter to begin the measurement. The instrument will automatically rotate the sample and take the reading. The results are displayed on the screen and saved to the database.\nYou can now record the reading and remove the sample. Repeat the process for any additional samples.\n\nBasic Maintenance and Troubleshooting\n\nProper maintenance is key. Always store the calibration tiles in their protective box when not in use.\nThe tiles can be cleaned with a soft brush, mild detergent, and water, or by carefully wiping with a lint-free towel and isopropyl alcohol. Avoid touching the surface of the tiles with your fingers.\nRegularly sweep away any loose granules from the turntable and surrounding area to prevent them from obstructing movement.\nIf the software ever tells you to remove the calibration box when it's already off, it means the sensors are dirty. Clean these three areas on the sensor head with a cotton swab and alcohol.\n\nSchedule a demo now:\nhttps://www.hunterlab.com/en/products/benchtop-spectrophotometers/aeros/","thumbnail_url":"https://cdn-thumbnails.sproutvideo.com/069adab61a1ce8ce8c/00af93d1cc1cdce3/1776782554/w_1280/poster.jpg?v=1776782635","thumbnail_width":1920,"thumbnail_height":1080,"video_id":"069adab61a1ce8ce8c"}
