Table 1: Pressure Verification Table
NOTE: If using Verify Calibration under Calibration Menu, increase pressure to 280mmHg slowly, to avoid
overshooting 280 mmHg and tripping the overpressure limit.
6.1.5 If any pressure reported by the Tango M2 is outside limits, the monitor must be calibrated (see
section 6.2.
6.1.6 Press ENTER to open the valves and release the pressure from the system.
6.1.7 Selecting EXIT or pressing the Start/Stop button will leave the Diagnostic Menu.
6.2 Set Calibration
Equipment required:
• Calibrated reference sphygmomanometer.
• 500ml volume.
• Hand Inflation Bulb with bleed valve
• Tubing, T-connector, and miscellaneous connectors
6.2.1 T-connector the sphygmomanometer, the 500ml volume and the inflation bulb together and
connect to the patient cable hose connection.
6.2.2 Access the Diagnostics Menu (see section 5.2).
WARNING: Any changes made within the diagnostic menu can alter BP accuracy. It is strongly
recommended that no changes are made to the Tango M2 Diagnostic Menu.
6.2.3 Select Calibrate from Diagnostics Menu and select Calibrate again.
6.2.4 Open the bleed valve on the pneumatic bulb to obtain 0mmHg pressure. Ensure the reference
sphygmomanometer displays 0mmHg and then press ENTER to set the zero point in the Tango
M2.
6.2.5 Close the bleed valve on the bulb and inflate to 250mmHg. Allow the pressure to stabilize,
adjusting as necessary to maintain the pressure at exactly 250mmHg on the reference
sphygmomanometer. Press ENTER to set the 250mmHg point into the Tango M2. Note: A failure
will be displayed if the monitor recognizes a pressure is outside reasonable expected limits of a
calibration pressure. The qualified user will be prompted to cancel (that calibration point will not
be set) or retry.
6.2.6 Calibration is now complete.
6.2.7 Select Verify Calibration and follow steps in 6.1. If verify calibration continues to fail, do not use
the Tango M2 monitor and contact SunTech Medical, Inc.
6.3 Leak Rate Test
Equipment Required:
• Stop Watch.
• 500ml volume.
• Hand Inflation Bulb with bleed valve.
• Tubing, T-connector, and miscellaneous connectors.
6.3.1 T-connector the 500ml volume and the inflation bulb together and connect to the patient cable
hose connection.
6.3.2 Access the Diagnostics Menu (see section 5.2).
WARNING: Any changes made within the diagnostic menu can alter BP accuracy. It is strongly
recommended that no changes are made to the Tango M2 Diagnostic Menu.
