Tech Note 1312 Detail

Spirometer shows an offset in the flow rate, or a drift in the total flow.

Affected Products:

PS-2152 PASPORT Spirometer

Problem/Symptom:
Spirometer shows an offset in the flow rate, or a drift in the total flow.

PASCO Solution:

To minimize the offset for the flow rate or drift for the total flow, make sure that the blue box amplifier for the spirometer is kept level with the text facing up. If the orientation of the amplifier box (where the transducer for determining the pressure difference is located) the weight of the diaphram can change the reading of the sensor.
