2. Operating Instructions
The scale has been designed and certified to weigh up to
200 kg
in
0.2 kg
increments. It has been
certified to weigh in temperatures between 5ºC and 35ºC.
The scale must not be used outside of these limits, as this will invalidate the N.A.W.I (Non
Automatic Weighing Instrument) certification that accompanies this Scale.
To weigh a patient follow the instructions below:
1.
Assemble the sling to the spreader and press the
ON/ZERO
pad. The display will show
0.0
and the
word
HOLD
in the lower left hand corner. This step readies the scale for weighing. The sling can
now be removed from the scale and placed around the patient.
2.
When the sling has been placed around the patient and reattached to the spreader bar, raise the
patient so that they are suspended from the scale. They must not be touching anything such as a
chair or bed since this will cause errors in weights.
3.
The scale has been designed to turn itself off after
1 minute
to conserve battery life. To restart the
scale, push the
ON/ZERO
pad one time only. The display will show the start up screen and then show
the patient weight. There may be a
KG
sign in the lower right hand corner of the display. This is an
indication that the weight is not stable. When the
KG
disappears, the weight is stable and can be
recorded.
WARNING: To restart the scale, be sure to push the ON/ZERO pad just once. If the scale starts
and the pad is pushed again, the scale may go to zero (0.0) and the patient weight may be lost.
This may require re-weighing the patient.
4.
The
RECALL
feature is designed to retain in memory the last stable weight over 10 kg. To access
this weight, the scale must be on. Press the
RECALL
pad. The display will flash between RECL
and the retained weight.
Maintenance:
It is recommended that twice yearly inspections of the connections on the scale be scheduled and
performed to assure trouble free operation. Look for wear or any irregularities that may contribute to
scale failure.
