Web Remote Control capabilities are embedded in the Spectrum Master, providing full instrument control through an HTML‑5 compatible browser. Ethernet connection is required. The ability to remotely monitor and control the instrument from the ground or desk enhances operator safety and efficiency when conditions make it unsafe or impractical to be close to the instrument. Login passwords can be used to allow access to authorized users only.

A remote connection terminates when the user logs out or closes the browser, or when the session time requested at login expires. To prevent multi-user conflicts, only one connection is permitted at a time. A second user who tries to log in will see a message indicating the instrument is currently reserved by another client, with the time remaining in their session.

While only one user can have control of the instrument, multiple users can view the same instrument using a desktop sharing application.
