5 - 13
of this time constraint, this number must be observed and recorded
prior to commencement of the 2nd run.
10. Calibrate Zero (0.000 lbs ) - 1st Run
10.1. (*D*) Press CONFIRM and observe the 0.00 LB prompt at the bottom of the display
as the motor begins its 1st run. Approximately 5 seconds later, the pump displays
the ZERO LBS A/D reading which remains displayed as the motor continues running
for approximately another 10 - 15 seconds. Record the ZERO LBS A/D number and
verify that this number is between 145 to 175 (145 < A/D number < 175). Record
“Pass” or “Fail” on the data sheet.
11. Pressure Sense Calibration Check - 2nd Run
11.1 When the motor stops, the PRESSENS prompt appears at the bottom of the display
and the pump immediately starts a 2nd run. Approximately 5 seconds later, the
pump displays the processed force measurement (in pounds) in Field #4.
11.2 (*D*) Continue watching the display for approximately 10 seconds and verify that the
(zero pounds) number remains at 0.0 ± 0.15 (-0.15 ≤ value ≤ +0.15) throughout this
time period. Record “Pass” or “Fail” on the data sheet.
11.3 If the readings observed and recorded in steps 10.1 and 11.2 are both within
specification, proceed IMMEDIATELY to step 12. If either reading or both readings
are not within specification, proceed as follows:
• Switch the pump “OFF” and “ON.”
• When the pump to prompts for a selection, enter access code 5089.
• Press CONFIRM four times and repeat Pressure Sensor calibration beginning
at 5.3.5.5, step 3.
12. Press
CONFIRM to prevent the load yoke from contacting the base of the barrel
clamp. The pump responds and an UPDATING message appears on the display for
a few seconds while the new calibration information is being saved. When this
message disappears, the new pressure sense calibration settings become stored
and a new message, VB SENSE, appears on the display.
CAUTION
To prevent corruption of the calibration data, do not turn off the pump
while UPDATING is being displayed.
13. Switch the pump “OFF” and remove the load yoke from the pump.
14. Remove the pump from the IV pole and remove the pole clamp from the pump.
