Manually determining the hold value
(hold)
The device is equipped with an autohold function. During the
measurement procedure, the weight is automatically frozen and displayed
in the HOLD window. It is possible that you will have to manually
determine the hold value, e.g. if the patient removes an item of clothing
after the initial weighing without stepping off the scale. For this purpose,
proceed as follows:
1. Press the hold button.
The display flashes until a stable weight is measured. The weight is
then continuously displayed. The
symbol is displayed (only for
calibrated models).
2. Read the measurement result.
NOTE:
When the patient steps off the device, the hold value will continue
to be displayed. As a result, you can attend to the patient before
recording the weight. To delete the hold value, press the
hold
button.
Balancing additional weight (tare) Using the tare function, you can prevent additional weight (e.g. a hand
towel or a support on the weighing platform) from influencing the weight
result.
1. Switch on the device.
2. Place the additional weight on the device.
3. Press the tare button.
The message “NET” appears on the display.
4. Ask the patient to position themselves on the device.
5. Read the measurement result.
The additional weight is automatically deducted.
6. To deactivate the TARE function, press the tare button again.
The message “NET” is no longer displayed.
NOTE:
The maximum displayable weight is reduced by the weight of the
objects already placed on the scale.
Permanently saving the additional
weight
(pre-tare)
Using the pre-tare function, you can permanently save an additional weight
and automatically subtract this from a measurement result. For example,
you can save a flat-rate figure for clothing and then always deduct this if a
patient is weighed when fully clothed. The pre-tare value continues to be
saved even after the device has been switched off.
1. Ensure that the device has no load.
2. Switch on the device.
3. Press the pre-tare button.
The number keypad appears.
The last additional weight saved is displayed.
4. Enter a different pre-tare value if desired.
5. In the number keypad, press the Enter key.
The entry is accepted.
The message “PT” appears on the display.
The value entered is saved and automatically subtracted from the
measurement result during the next weighing procedure.
The number keypad is no longer displayed.
