Special Features

Tanita Corporation’s electronic scales come standard with these special features:

1.Autozero: The scale will automatically display “0” when turned on. If a foreign object is placed on the platform before turning the scale on, it will automatically zero out that object’s weight.

2.English-Metric Readout: You may switch between metric (kilos) and English (pounds) readouts before or after a reading, and the scale will convert one reading to the other.

3.Recalculate Weight: If the first reading of a patient’s weight is suspect, a second reading can be taken without removing the patient from the scale. To reweigh the patient, simply depress the Zero switch.

4.Average Weight: In most cases, the 3500 Scale displays an actual weight based on a series of consistent stable measurements. However, if the wheelchair/patient keeps moving, the scale may not get the readings required to give a “stable weight.” In these instances an average weight can be determined by activating the Average Locking feature. Depress the Pounds (or Kilos) switch (dependent upon measurement mode). The indicator light should start flashing. A weight should appear in place of the moving dashes. Depress the Pounds or Kilos switch again to deactivate the feature.

5.Zero Ability: The operator can “zero out” the weight of a blanket, etc., upon which a patient is to be weighed.

OPERATING INSTRUCTIONS

Using the Zero Function

When using the Stand-on Scale, the weight of any object accompanying the patient (blanket, etc.) must be taken into account during a weighing. Weigh the object(s) by themselves to determine their weight and subtract this weight from the combined weight of patient and object(s).

METHOD 1

1.Scale is off.

2.Place the object (blanket, etc.) on the scale platform.

3.Turn the scale on. The scale will now zero out the weight of the chair leaving a “0” reading on the display.

METHOD 2 – Use for objects under 12.5 lbs.

1.Turn the scale on. Wait for display to read “0.”

2.Place the object (blanket, etc.) on the scale platform. The display will read the object’s weight.

3.Depress the Zero button to zero out the weight of the object. The display should read “0.”

Note: The Zero button has a dual function. If the weight of the object is greater than 12.5 lbs., the scale will reweigh the object instead of zeroing it out when the button is depressed. IN THIS CASE, YOU MUST USE METHOD 1 TO ZERO OUT THE WEIGHT OF THE OBJECT.
