7-2 Calibration
This is a precision instrument. Perform a checkup periodically.
Checking the pressure accuracy
Connect the pressure generator and the manometer to the instrument as shown in the illustration.
Use the optional 500-cc cylinder or the cuff wrapped loosely around a cylinder.
While holding down the HOME key, turn on the POWER switch. "M01" appears at the upper left of the
display.
Press the NIBP START/STOP key to be in the pressure calibration mode. The pressure value appears in
the SYS/DIA display. Pressurize to 200 mmHg, and then 100 mmHg, using the pump. Compare the value
displayed on the instrument with the pressure displayed on the manometer. The difference should be
within ±4 mmHg.
Turn off the POWER switch.
Checking the exhaustion speed
Connect the optional 500-cc cylinder or the equivalent to the instrument as shown in the illustration.
While holding down the HOME key, turn on the POWER switch. "M01" appears at the upper left of the
display. Press the
key to display "M02".
Press the NIBP START/STOP key to start constant exhaustion. The pressure value appears in the middle
left display and the exhaustion speed in the lower display. The exhaustion speed displayed after checking
should be 50±20 (5.0±2.0 mmHg/sec).
Turn off the POWER switch.
If the accuracy can not be obtained, contact your nearest A&D sales representative for inspection.
