Weighing methods
Method A.
How to start weighing with the resident already placed in the sling:
- Raise the lift so the sling with the resident is clear of the floor, bed, etc.
- Push the ON/OFF button.
- Read the gross weight (the weight of the resident + the weight of the sling) on the display.
To get the net weight, weigh the sling and subtract that weight from the gross weight.
Method B.
How to start weighing before placing the resident or the sling:
- Push the ON/OFF. button
- Wait about 10 seconds until 0.0 kg/ lbs are shown on the display..
- Place the resident in the sling on the lift.
- Raise the lift so the sling with the resident is clear of the floor, bed, etc.
- Read the gross weight (the weight of the resident + the weight of the sling) on the display.
Method C.
How to weigh the resident without counting the sling weight:
- Push the ON/OFF. button
- Wait about 10 seconds until 0.0 kg/lbs are shown on the display.
- Put the sling in place, clear of the floor, bed, etc., and push the button G/N. The weight of the sling is now tared away and the display shows a Net 0.0 kg/lbs
- Place the resident in the sling on the lift.
- Raise the lift so the sling with the resident is clear of the floor, bed, etc.
Read the net weight (the weight of the resident) on the display.
Switching off
