Tanita 3500 - Manual (Page 5)

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.

Primary Function
Depress to turn scale
on or off.
Depress to display
weight in kilograms
(light over switch will
illuminate to indicate
kilogram mode).
Depress to display
weight in pounds
(light over switch will
illuminate to indicate
pounds mode).
Zeros out the weight
of a foreign object
(e.g. blanket placed
on platform).
Secondary Function
While in Kilos mode, depress for average
reading when excessive movement
prevents stationary measurement.
Depress after any reading to “lock”
reading. Reading remains displayed for
approximately 1 minute after patient is
removed from scale, or until switch is
depressed again. Kilos light will flash to
indicate average or locked reading.
Depress while in Pounds mode to
average reading.
Depress after any reading in pounds
mode to “lock” in reading. Light will flash
to indicate average or locked reading.
Depress after initial weight is taken to
reweigh individual.
