CBX-iT™ PWM Checker
See the control board’s PWM signal to the EEV motor in real time—so you know exactly what’s working and what’s not.
Meet the CBX-It™ PWM Checker
It connects in-line with the EEV motor and provides a visible pulse readout—so you can verify the board’s output instantly.
✔ Confirm board output in seconds
✔ Avoid unnecessary valve replacements
✔ Diagnose faster on live systems

The Hardest Part of EEV Diagnostics Isn’t Access—It’s Visibility
You can’t see the signal from the board to the valve.
So you’re left guessing:
• Is the board working?
• Is the motor responding?
• Or am I about to replace a part that isn’t even the problem?
It doesn’t test the valve. It proves the board.
No special setup. No System disruption.

Know Before You Replace Anything
If this tool helps you avoid one misdiagnosed part or return visit, it’s already paid for itself.
Less time diagnosing means more calls per day.
