6. Calibration Check
Welch Allyn recommends that the calibration of the ABPM 6100 monitor be verified annually
by the user using the following procedure:
1. With the ABPM 6100 unit already powered up, remove one of the AA batteries from the
battery compartment. Then immediately replace the battery back in its proper
orientation, which will result in the unit to start the power up cycle.
2. While the LCD is displaying dashes, press and hold down the Start/Stop button. The
unit will display the software version, the battery voltage, followed by a click as the
valves are closed. When the process is finished, a pressure value will be displayed on
the LCD and the unit is ready to have the calibration checked.
3. Disconnect the ABPM 6100 monitor cuff assembly from the unit
4. Attach the appropriate end of ABPM 6100 Y-connector (Welch Allyn Part #6100-25) to
the monitor. Attach a cuff to the appropriate end of the Y-connector, and wrap around a
suitably sized can or bottle. This acts as the reservoir for the unit. Connect the third leg
of the Y-connector to a high quality, known pressure standard1. Refer to the calibration
figure below for a sketch of the test set up.
5. Pressurize gauge to 250 mmHg and compare against pressure standard (see Note
below). If the unit does not meet the required calibration, unit needs to be returned to
Welch Allyn for calibration or repair.
6. Bleed pressure down no faster than 10 mmHg per second, stopping to check the
pressure at 250, 200, 150, 100, and 50 mmHg
7. When finished, remove one of the AA batteries from the battery compartment. Then
immediately replace the battery back in its proper orientation, which will cause the unit
to start the power up cycle.

Note: Your ability to measure the accuracy of the ABPM 6100 depends upon the sensitivity
of the pressure standard you use for the calibration procedure.
• If using a manometer (mercury column or aneroid gauge) rated at ± 3.0 mm Hg, you will
be able to determine the accuracy of the unit being tested to within ± 6.0 mm Hg.
• If using a device (e.g., digital pressure standard) rated at ± 1.0 mm Hg, you will be able
to determine the accuracy of the unit being tested to within ± 4.0 mm Hg.
