Wheelchair Scale with Seat Operation Manual - Scale Operation 9
The keys on the front panel display are very sensitive so only a gentle pushing motion is required to
obtain results.
The scales have the capability of performing different operations beyond just calculating weight. The various
operating instructions are described below.
4.1 Weighing
Use the following steps to weigh a person.
1. Press the On/Off key to turn on the scale and 0.0 will appear on the display along with ZERO on the upper
display.
2. When the person step on the scale the display shows the person’s weight. The LOCK annunciator is on in
the upper display and beeps to indicate the end of the weighing process.
3. To change the display from kg to lb and vice-versa, press the LB/KG key.
4. To turn off the scale, press and hold the On/Off key until OFF appears on the display.
4.2 Hold/Release Function
Use the following steps to use the Hold/Release function.
1. When the person is on the scale, press the Hold/Release key.
2. When the person steps off the scale, the weight and the HOLD & LOCK annunciator will remain on the
display.
3. At this stage the Zero key will not work. The only way to return to zero from here is to press the Hold/
Release key one more time.
Pressing the Hold key prior to a person getting on the scale will also work.
4.3 Preset Tare
Use the following steps to use the Preset Tare.
1. When the weight is set to 0.0 , place the extra load on the scale. Press the TARE key until the display
returns to 0.0 and NET appears on the display.
2. Remove the extra load from the scale. The weight will appear with a negative symbol to the left of it.
3. Ask the patient to step on the scale with the extra weight. The display shows the patient’s weight. The
NET annunciator is still on. The weight of the extra load remains stored in memory.
4. To cancel the tare weight, press and hold the TARE key until NET disappears from the display and the
display turns back to 0.0 and GROSS appears. Tare weight is also canceled when the scale is turned off.
