• Protective case: Consider getting a protective case for the OBD digital meter. It protects it from accidental drops, scratches, and exposure to sunlight or extreme temperatures inside the vehicle.
• Update firmware: If the OBD digital meter has a firmware update feature, check with the manufacturer regularly for updates. New updates can improve performance, add new features, and fix known issues.
• Check the OBD port: Periodically inspect the OBD-II port on the vehicle to ensure it is clean and free of debris. A dirty or damaged port can affect the connection and the meter's performance.
• Monitor battery: Some advanced OBD digital meters have a built-in battery for data logging or wireless communication. Monitor the battery level and replace it when necessary to ensure uninterrupted operation.

How to choose OBD digital meter

When buying an OBD digital meter for retail business, the first consideration is the target market. Different car owners have varying preferences, so it's good to have a variety. Choose an OBD digital meter with different features, such as reading and clearing codes, live data display, and vehicle compatibility. Stock up more on the popular ones.

Consider the ease of use and installation. Many customers will prefer the OBD digital meters that are easy to install and use. Meters that are simple to install require minimal or no tools, such as screwdrivers. They plug into the OBD-II port and are secured with adhesive or brackets. These are the ones that a DIY person can install. OBD digital meters that are more complicated to install require more tools and technical knowledge. They are connected to the OBD-II port using a serial adapter and installed on a custom mount, which requires drilling. Look for OBD digital meters that are easy to install and avoid those that need professional installation.

Check the readability of the display screen. The size and quality of the display screen matter a lot. People will prefer meters with larger screens that are bright and clear. The vehicles’ dashboards have different lighting. Also, consider the viewing angles. Can one see the data on the display screen from different angles? Stock more of the OBD digital meters with adjustable screens.

Many customers will prefer an OBD digital meter that can be powered directly from the car's battery. It will draw power from the battery and keep the vehicle's OBD-II port live even when the vehicle is turned off. It is a great choice for people who want to monitor their vehicles’ data, especially the performance ones. The only disadvantage is that it will drain the car's battery. Because of this, some people will prefer the OBD digital meter that can be powered through the vehicle’s data port. It will draw power from the dashboard and won't drain the battery. Choose both types to cater to different customers' preferences.

Lastly, consider the price of the OBD digital meter. Some have additional features that land them on the higher end of the price scale. The advanced ones have a data logger that records and saves data for future reference, a GPS that tracks the location of the vehicle, and an alarm system that notifies the driver of various issues. They are all suitable for luxury and high-end vehicles.

How to DIY and Replace OBD Digital Meter

One can easily install an OBD digital meter with basic tools and follow the instructions in the manual. Below are some steps on how to DIY and replace an OBD digital meter.
