This page shows numerous screen images of the SDI-12 Verifier's PC software. The starting point is the basic command test; it checks to see how a sensor responds to each and every SDI-12 command:

You can transmit SDI-12 commands one at a time to seen exactly how the sensor responds:

You can alter timing attributes to communicate with sensors that may not be in compliance with the SDI-12 standard:

You can manually transmit a break:

The Verifier executes a variety of complex tests on sensors:

The comphrensive sensor tests automatically runs each sensor test and produces a test report:

The Verifier can monitor the SDI-12 bus, operate as an SDI-12 data recorder, and simulate a sensor. It also has an SDI-12 transparent mode. These features help find and correct problems with SDI-12 devices.

This screen shows the monitor mode, when a sensor is not connected to an SDI-12 data recorder, showing the retries issued by the data recorder. Note that the Verifier places time stamps on the bus transactions.
