CALIBRATION AND ACCURACY TESTING
WARNING!
Check the accuracy of this device every two years or after any
mechanical impact (such as a fall) to ensure accurate readings.
The meter's accuracy can be checked visually. Just make sure
the manometer's needle (5) rests on 0 mmHg in the dial when
the unit is completely deflated. If the needle of the manometer (5)
deviates from the 0 mmHg reference point, calibration is required
(see Fig. C).
IMPORTANT: Tolerance Range: +/- 3 mmHg from the center of the
0 mmHg position. Recalibration is needed if the needle falls out-
side this range.
• Gently disconnect the PVC tube (10) from the manometer (5), pay-
ing attention not to damage the tube.
• Place the Y-shaped tool (9) provided to adjust the manometer's
needle (5), placing it around the air intake hole (12).
• Rotate it gently clockwise to move the needle (5) left. Subsequent-
ly, rotate the tool (9) counterclockwise to shift the needle (5) to the
right.
• Align the needle back to the 0 mmHg mark.
• After adjustment, remove the Y-shaped tool (9).
• Gently reconnect the tube (10) to the air intake hole (12).
WARNING!
Avoid adjusting the needle inside the manometer (5) with the Y-shaped
tool (9) beyond the specified tolerance range of +/- 3 mmHg. Oth-
erwise the device will get damaged. If the device remains unstable
post-calibration, contact your retailer.
