How can I check the BNC outputs of the MPVS Ultra are functioning correctly?

Check the wiring of the output cable. The center conductor must be the signal (+) and the outer conductor must be the ground/shield.

Measure the voltage directly at the BNC output connector using a voltmeter. The voltage outputs should be as follows:

Channel Calibration Setting Approximate Voltage
Pressure 1 and 2 0 mmHg 0 V
Pressure 1 and 2 25 mmHg 0.25 V
Pressure 1 and 2 100 mmHg 1 V
ECG 1 mV 1 mV

The value selected in the Volume box on the Catheter Calibration screen in the Control Interface Software is the value that the MPVSUltrais outputting. Verify that each signal is functional by observing the respective indicators on the front panel.
