Pulse Channel DC Offset Test (9a, 9b, 9c)

Select Room Number and Bed Letter per Table 5-7 on page 5-11, and press the NIBP
START key to activate the test.
This test measures the DC offset for each of the three electronic gain settings available on
the pulse channel. Results for each gain setting are displayed in the Timer/Temperature
display (in Volts). Table 5-7 on page 5-11 describes the tests performed.
Press the DEFLATE key after each test to exit.

Pulse Channel Average Noise Test (10a, 10b, 10c)

Select Room Number and Bed Letter per Table 5-8 on page 5-11, and press the NIBP
START key to activate the test.
This test measures the average noise for each of three electronic gain settings available on
the pulse channel. Results for each gain setting are displayed in the Timer/Temperature
display (in millivolts). Table 5-8 on page 5-11 describes the tests performed.
Press the DEFLATE key after each test to exit.

Main Pressure Transducer Verification Test (11a, 11b, 11c)

NOTE:
This tests the calibration of the main pressure transducer in LOW, MED, and HIGH
modes. This is done by comparing the readings of the UUT to an external pressure gauge
in LOW mode below 100 mmHg, in MED mode between 100 mmHg to 200 mmHg, and
in HIGH mode between 200 mmHg to 300 mmHg. In the event of a disagreement between
the device and an external gauge, the transducer must be calibrated by performing the
calibration in section 5.5.15 "Main Pressure Transducer Calibration" on page 5-14.
1. Select diagnostic test "11" (Room) "a" (Bed).
