Merit Medical Mentor Simulator/Tester - Manual (Page 7)

2. Simulate a pressure signal by selecting one of
the four pressure values (0, 50, 100, 300
mmHg) using the Pressure Simulator Switch on
the right side of the Mentor housing.
3. Observe that the monitor waveform values
match the pressure values on the Mentor.
If the pressure readings continue to differ by
more than the sum of the accuracy
specifications of both the Mentor and the
monitor, the problem resides in the cable
or the monitor. Replace the Meritrans Reusable
Cable to determine whether it is the fault of the
cable or the monitor.
If the pressure readings on the Mentor and the
monitor are the same, then the cables and the
monitor are functioning correctly and the
transducer is faulty. Replace the transducer and
repeat directions one through eight as
described in Section I.
If there is still a discrepancy between the
readings on the Mentor and the monitor after
replacing both the Meritrans Reusable Cable
and/or the transducer, check the calibration of
the Mentor using a Sphygmomanometer as
outlined in Section VI.
If the Mentor demonstrates proper calibration,
the monitor is at fault. Have the hospital‘s
biomedical engineer or the monitoring
equipment’s technical support team check
the monitor.
In the event that the Mentor is dropped,
physically damaged or misused in any way,
please check the calibration accuracy.
