TEST MODE PROCEDURE (CONTINUED)
4. Air/Occlusion Sensor voltage Checks (continued)
NOTE:
a. Be sure to use tubing specified for use with your unit
(see front panel/case top of unit).
b. Be sure tubing in front of sensor is fresh, not worn,
flat or creased. -
c. Be sure unit and tubing are not cold. Unit should -
have been at room temperature for at least 3 hours. jE | Pump ΟΛΜΕ
d. Use at least 5 different tubes in each unit, preferably
all from different lots (especially for recalibration
checks). Test sets are available from SIGMA.
e. Checking occlusion function with a pressure gauge: -
allow for approximately 4 feet of tubing between the s
unit and the pressure gauge. Bleed all of the air from tep e
the line, Y-site and gauge. When the line is 一 >
occluded, the displayed occlusion voltage reading
should increment by at least 4 per revolution of the
pump after the first occluded revolution.
f. Pinch off within 1” of the bottom of the unit will
increase occlusion numbers +100 or greater within 1-
