Swivel Lift Scale Calibration Procedure
It is very important that you use an absolutely accurate 25 lb. weight. If not,
you will have variations in your patient weighing.
Requirements: Calibrated 25lb. weight.
1. To enter the calibration mode, first press and hold the “ON / ZERO” pad.
While holding the “ON / ZERO” pad, press and hold the “LB / KG” pad.
After approximately 3 (three) seconds the message on the display will
change from “ZERO” to “CAL”. Release both pads at this time and the
display will show the “C 0” message.
2. Make sure the chair is empty and not in contact with any part of the tub
and is *stable (not moving or vibrating). Press the “ON / ZERO” pad once
again. The indicator will count down from “8” to “0”. When finished, the
indicator will show “C 25”.
3. Place the 25lb calibrated weight on the chair, allow it to stabilize* and
press the “ON / ZERO” pad once again. The indicator will again count
down from “8” to “0” as before and then will read “25”. Remove the weight
and the indicator should read “0”. The indicator then automatically returns
to the normal weighing mode. Calibration is now complete.
*Failure to stabilize the unit during the calibration process may cause the scale
to display an inaccurate weight or not permit calibration.
