Which detail is not required to be clearly marked for general identification on a measuring device?

For general identification on a measuring device, it is essential to have certain details marked clearly to ensure proper use and traceability. Among the listed options, the address of the manufacturer is typically not required to be marked directly on the measuring device.

The type of measuring device, model number, and serial number are all critical for identification purposes. The type allows users to understand what the device measures, the model number helps in identifying specific product lines or variations, and the serial number provides a unique identifier for that device, facilitating tracking, maintenance, and warranty services.

In contrast, while knowing the manufacturer's address can be useful for consumers or regulatory purposes, it is not generally mandated to be displayed on the device itself. Therefore, the absence of the manufacturer's address does not hinder the device’s identification or functionality in the same way that missing the type, model number, or serial number would.
