You can also follow along with our <a href=\"https:\/\/youtu.be\/OpgShyG6F3g?si=bgWQuqzbB0LT107A\">video tutorial<\/a> for a visual reference.<\/p>\n\n\n\n<figure class=\"wp-block-embed aligncenter is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<iframe loading=\"lazy\" title=\"Calibrate Q45 and Q46 Dissolved Ozone Meter\" width=\"500\" height=\"281\" src=\"https:\/\/www.youtube.com\/embed\/OpgShyG6F3g?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe>\n<\/div><\/figure>\n\n\n\n<h5 class=\"wp-block-heading\">Step 1: Verify the Dissolved Ozone Level<\/h5>\n\n\n\n<p class=\"wp-block-paragraph\">Before calibrating, confirm the current dissolved ozone level in your system. This benchmark will guide you in setting the sensor correctly.<\/p>\n\n\n\n<h5 class=\"wp-block-heading\">Step 2: Access the Calibration Menu<\/h5>\n\n\n\n<p class=\"wp-block-paragraph\">From the sensor\u2019s main menu, navigate to the calibration option:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>Enter the Calibration Menu<\/strong>: Press &#8220;Enter&#8221; to begin.<\/li>\n\n\n\n<li><strong>Select Calibration Type<\/strong>: You\u2019ll see two options: &#8220;Reference&#8221; and &#8220;Zero.&#8221;<\/li>\n<\/ol>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Zero Calibration<\/strong>: Use this only if the sensor has been consistently reading zero or if you know there\u2019s zero dissolved ozone in the water. This is generally less common.<\/li>\n\n\n\n<li><strong>Reference Calibration<\/strong>: This will be the primary method for adjusting the sensor to match a known reference point.<\/li>\n<\/ul>\n\n\n\n<h5 class=\"wp-block-heading\">Step 3: Calibrate the Reference<\/h5>\n\n\n\n<p class=\"wp-block-paragraph\">For most applications, calibrating the reference level is the focus:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>Select Reference and Wait for Stabilization<\/strong>: After pressing &#8220;Enter&#8221; on the reference option, allow the dissolved ozone level to stabilize. Calibration should only be done when the reading has reached a steady point.<\/li>\n\n\n\n<li><strong>Adjust the Value<\/strong>: Once the reading stabilizes, use the &#8220;Over&#8221; button to navigate between digits, and the &#8220;Up&#8221; button to increase values. Adjust the reading to match your verified ozone level (e.g., 2.0 ppm).<\/li>\n\n\n\n<li><strong>Confirm Calibration<\/strong>: When the display reads close to your target, press &#8220;Enter.&#8221; For example, if you\u2019re calibrating to 2.0 ppm, aim for a similar reading, such as 2.01 ppm, for precision.<\/li>\n<\/ol>\n\n\n\n<h5 class=\"wp-block-heading\">Step 4: Review the Slope<\/h5>\n\n\n\n<p class=\"wp-block-paragraph\">After confirming the calibration, the display shows your slope value, which indicates the sensor\u2019s accuracy relative to its original factory settings (typically 100%).<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Interpreting the Slope<\/strong>: If you see the slope significantly diverging from 100%, it might indicate the need to replace the sensor\u2019s electrolyte solution and membrane. These replacements can bring the sensor back to optimal calibration.<\/li>\n<\/ul>\n\n\n\n<h5 class=\"wp-block-heading\">What\u2019s Next?<\/h5>\n\n\n\n<p class=\"wp-block-paragraph\">If your slope is too far from the factory standard, it may be time for some maintenance.
