The ABM EasyHood is a specialized tool designed for accurately measuring airflow volumes from air supply or return/exhaust vents in residential and commercial buildings. It is used in conjunction with an ABM-200 Airflow & Environmental Meter (or ABM-100 Airflow Meter) and a smartphone running the free CPS Link™ app. This integrated system provides a comprehensive solution for HVAC airflow measurement, offering both precision and affordability.

Function Description

The primary function of the ABM EasyHood is to capture and measure airflow. When placed over a vent, it directs the air through an internal vortex airflow straightener, ensuring that the airflow is consistent and measurable by the integrated meter. The ABM-200 meter, which is included with the ABM-HOOD-200 model, not only measures airflow but also provides environmental data such as temperature, wet bulb temperature, dew point, and relative humidity. This allows for a more complete understanding of the air quality and HVAC system performance. The ABM-100 meter, if used, focuses primarily on airflow measurement.

The device is designed to work seamlessly with the CPS Link™ app on a smartphone or tablet. The app serves as the display interface, showing real-time data, and also allows for storing and sending measurement data. This smart connectivity enhances the user experience by providing online guidance and visual instructions, making the operation straightforward even for complex tests.

Usage Features

The ABM EasyHood offers several features that simplify its use and enhance its functionality:

Smartphone Integration: The device includes an adjustable spring-lock smartphone platform, allowing users to securely mount their mobile device for easy viewing of data and app interaction. This hands-free mobile phone use is particularly convenient during testing.
CPS Link™ App: The dedicated app is central to the device's operation. It guides users through the testing process, displays all measured values, and manages data. The app is optimized for various Apple and Android operating systems, ensuring broad compatibility.
Quick Start Guide: The manual provides a clear quick start guide, detailing the steps for app download and setup, meter installation, and performing both regular and low volume tests.
Regular Test Mode: This mode is used for airflow volumes ranging from 35 to 720 CFM (59 to 1,223 M³/H). Users simply select "REGULAR TEST" in the app, place the hood over the grille, and the app automatically calculates and displays airflow and other values. The test can be stopped manually or ends automatically after 30 seconds.
Low Volume Test Mode: For lower airflow volumes, specifically 7 to 100 CFM (12 to 170 M³/H), a Low Volume Adapter is inserted into the vortex grille. This adapter helps to accurately measure smaller airflow rates. The process is similar to the regular test, with the app guiding the user and calculating values.
Expansion Hood Setup: The ABM EasyHood can be expanded to accommodate larger grilles, up to 24" x 24". This involves a simple setup process to attach the expansion fabric and poles, increasing the versatility of the device for different vent sizes.
Data Management: The CPS Link™ app allows users to save test sessions and retrieve test reports from a "Job File," facilitating record-keeping and analysis.
Bluetooth Smart Connectivity: The ABM-200 meter connects wirelessly to the mobile device via Bluetooth Smart, offering a connection range of up to 100 ft (30.5 m), although this range can be reduced by interior obstructions.

Maintenance Features

Maintaining the ABM EasyHood and its components is crucial for ensuring accurate and reliable performance:

Battery Replacement (ABM-200): The ABM-200 meter is powered by a CR2450 Coin Cell Lithium battery. The manual provides clear instructions for replacing this battery. This involves squeezing both sides of the rubber "skin" and pushing upwards, pulling the "skin" over the back of the housing to expose the battery compartment, opening it, replacing the coin cell, and then reinstalling the "skin." The battery life is rated for over 500 hours.
Troubleshooting Guide: A comprehensive troubleshooting guide is included in the manual to address common issues users might encounter. This covers problems related to the CPS Link app (crashes, pairing issues, freezing), meter readings (inconsistent or inaccurate airflow), and connection status indicators (blue, yellow, and flashing red dots for pairing status).
Replacement Parts: The manual lists available replacement parts, including the Phone Base Door, Rubber Seal, Expansion Base, Expansion Fabric, Expansion Pole, and Low Airflow Plate. This ensures that users can easily obtain necessary components to repair or maintain their device.
Cleaning: While not explicitly detailed in the provided excerpt, general maintenance for such devices typically involves keeping the airflow seal and internal components free from dust and debris to ensure accurate readings. The durable molded housing is designed to withstand regular use.
Warranty: CPS Products, Inc. offers a one-year warranty against manufacturing and material defects from the date of purchase, covering repairs or replacements. This warranty underscores the manufacturer's commitment to product quality and provides assurance to users.
