Scale Systems
Compella™ Bariatric Bed System Instructions for Use (178951 REV 6) 47
Warning—Zero the scale before a new patient is put on the bed and whenever additional equipment is
added to the bed. Make sure to include standard linens on the bed during the zero process. Failure to do
so could cause an inaccurate weight reading; patient injury could occur.
NOTE:
• If the bed is equipped with the IntelliDrive® XL Transport System, you can not zero the scale or
weigh a patient when the bed is in Transport Mode because the weigh frame will be off-
loaded by the drive wheels making contact with the floor.
• If you attempt to use the scale while the bed is in Transport Mode, the Raise
Bed control indicator on the control pod will flash 5 times and you will hear a
triple beep. To raise the bed, press and hold the Raise Bed control until its
indicator turns off and you hear the single confirmation beep.
To Zero the Scale
1. Press the Enable key.
2. Make sure that the bed is in the Scale Reference position (see “Scale Reference
Position” on page 46). When you release the brake for this position, the Brake Not
Set alert will sound and the Scale Reference indicator will come on solid.
3. Press and hold the 0/T control; Hold will show on the display.
4. Release the control when 00.0 shows.
5. After you release the control, the display will flash CALC. Do not touch the bed until
the display stops flashing CALC.
When CALC stops flashing, you will see 0.0 on the display, the 0/T control indicator
will be green, and you will hear a single beep. The zero process is complete. You can engage the
brake at this time.
Weigh the Patient
Before you weigh the patient, make sure of these:
• All items on the list defined in the “Bed Setup” section are accounted for (see “Bed Setup” on
page 43).
• Remove drainage bags, excess linen, and equipment that has been added since the scale was
zeroed.
• The patient is lying still and is centered on the support surface.
•The bed is not in Transport Mode.
• The bed is in the Scale Reference position (see “Scale Reference Position” on page 46).
For maximum scale accuracy when you weigh the patient, the bed should be in the Scale Reference
position; however, if necessary, you can weigh the patient when the bed in not in this position.
To weigh—press and release the Scale control. On release of the Scale control, the
display shows the current patient weight in kilograms. At this time, you may set the
Brake.
