Using the Tare Function
You can use the tare function for deducting an extra weight (such as a wheelchair, or medical equipment attached
to the patient) in a weighing operation.
Use the following steps to use the tare function.
1. With the scale set to
0.0
, place the extra load on the scale. The display shows
WEIGH
and then the weight
of the load.
2. Press and hold the
TARE
key until
TARE
appears on the display. The display returns to 0.0 and
TARE
appears on the left side of the display.
3. Remove the load from the scale. The weight of the load appears with a negative symbol to the left of it.
4. Ask the patient to step onto the scale with the load. The display then shows the patient’s weight without
the weight of the load.
5. The weight of the load remains stored in memory, so you can continue to weigh patients who are
carrying the same tare weight. For example, when using the same wheelchair for weighing more than
one patient.
6. To cancel the tare weight, press and hold the
TARE
key until
TARE
disappears from the display. The tare
weight is also cancelled when the scale is turned off.
Use the following steps to enter a tare without placing that item on the scale. An example of this would be if
you’ve got a patient in a wheelchair and the wheelchair has a known weight (has been tagged) you can enter that
weight manually.
1. With the scale set to
0.0 Lbs
(there must be no weight on the scale), press the
TARE
key. The display will
alternate between a value and the word
TARE
.
2. To change the value, press and hold the
Kg/Lb
key until the right most digit is equal to the first digit of the
value you want. Example: If you want 103.5, hold the key until the display is
0.1
.
3. To advance to the next digit, press the
Kg/Lb
key twice quickly. The digit you changed will move left and
the right most digit will again be
0
. Again, hold the
Kg/Lb
key until the right most digit is equal to the
next digit in the numbers you want.
4. Continue as in Step 3 until you are displaying the value you want, then press the
TARE
key.
5. You can now accurately weigh the patient.
6. To cancel the tare weight, press and hold the
TARE
key until
TARE
disappears from the display. The tare
weight is also cancelled when the scale is turned off.
