BASIC SYSTEM OPERATION 

 

PATIENT WEIGHING: 

STEP 1

:  Place scale on hard smooth floor surface to ensure accurate data. 

NOTE:

  Avoid carpeting or uneven flooring surfaces.

 

STEP 2

:  The scale will automatically turn on when weight is detected over five pounds and then 

lock in on a stable weight 

Alternatively,

 

press  the  “

Zero/Weigh

”  button  and  wait  for  the  display  to  indicate 

“ZERO”. Release the

 “Zero/Weigh” 

button and the display will read

  “0.0”

.  Position 

the patient on the platform. Weight will be displayed in a few seconds. A stable weight 
will automatically be stored in memory.

 

STEP 3

:  To manually hold a weight reading at any time during the weighing process, press the 

Hold/Recall

” button. 

NOTE: 

When the scale is off, pressing any of the buttons will turn on the scale. Press 

and  hold  the 

“Zero/Weigh” 

button  to  erase  the  last  held  weight  from 

memory. Only the last stabilized weight will be held in memory.

Scale is zeroed and stabilized 

 

Weight is locked in memory (next stable weight will override memory).
