A test apparatus that guides an end user through visualization of a user interface on a web browser that is easy to operate for individuals with limited knowledge of the devices or test protocols for gas meters. The test apparatus may include the executable instructions having instructions that configure the processor to, receive input data from the web browser; compare the input data to data in a data table; select an entry from the data table that reflects a match between the input data and data associated with the entry in the data table; and generate a first output that defines a configuration for a user interface that renders on the web browser, the configuration representing a stage of a test initialization process to configure operating parameters on the controller to work with a meter-under-test that couples with the fluid moving unit for purposes of conducting a meter proof.
