Section 2. Battery Operation
Battery Installation
The indicator can be powered by a set of six AA alkaline batteries. These
batteries can perform over 25,000 weighments of typical use with the standard
Automatic Shutoff Timer settings.
The battery compartment is located on the backside of the indicator. Press the
locking tab to release battery compartment cover. Completely remove all the
batteries from the indicator and install the new set of batteries. Be sure the
batteries are oriented properly. Reinstall the battery compartment cover to
complete the battery installation.
Battery Indicator
The battery indicator displays the remaining battery life available. A low battery
status is also indicated by two beeps when a weight is held (If Parameter BH is set
to on.) This indicator will not be displayed if the scale is powered by its wall
transformer.

Section 3. Scale Operation
Fig. 3 Front Panel
Display Pushbuttons
The Model DS6150 controls consist of UNITS, ZERO, REWEIGH, ▲, ▼, and
BMI buttons. The display is used to provide weight indications and operator
messages indicating scale operation.
Power On/Off
Press the ZERO button to turn on the indicator. Press and hold the ZERO button
for 3 seconds to turn off the indicator. The indicator has an adjustable Automatic
Shutoff Timer that will turn off the indicator when not in use.
Zero When the ZERO button is pressed, the scale will reset to zero weight. This
feature can be used to zero out any weight not desired to be part of the patient
weight. The current BMI entry will be changed back to a 0.0 value.
UnitsPress the UNITS button to toggle between lb and kg weighing units. The current
unit will be displayed to the right of the weight digits. NOTE: The UNITS button

6
can be locked or unlocked by pressing and holding UNITS for 5 seconds. An “ L
on “message is displayed when button is locked and “ L off “ when unlocked.
Reweigh
To reinitiate the weighing process, press REWEIGH. This will allow a new
measurement to be taken without the patient having to leave the platform.
BMI With the held weight being displayed, press the BMI button to enter the height of
the patient. Adjust the value by using the ▲or ▼buttons. NOTE: Select the
Height units by pressing the UNITS button to toggle between the height in inches
or centimeters. The scale will exit this mode if no buttons are pressed within 30
seconds.
Display Annunciators
The display annunciators will indicate the scale status.
Motion
When the scale senses motion, MOTION will be indicated. Once motion ceases,
a stable reading will be displayed.
Stable Hold
Indicates a stable weight has been achieved and held on the display. This
indicates an accurate weight has been achieved. Note: Weights below 4.5
pounds will not be held.
Average Hold
Indicates that the weight held on the display is a result of averaging several
weights due to excessive motion on the scale. Note: Weights below 4.5 pounds
will not be held. The Average Hold weight may be slightly less accurate than a
Stable Hold weight.
Displaying an Average Hold weight instead of a Stable Hold weight will speed the
weighment process for patients that are not able to remain still. The Average
Hold weight will differ from the patient’s actual weight based upon the severity of
the motion caused by the patient while on the scale. Although this weight may be
less accurate than a Stable Hold weight, the deviation from the patient’s actual
weight will be minimal.
The time required for the Average Hold to engage is based upon the Average
Aperture parameter. See the Parameter Setup section for configuration
instructions.

7
Battery Indicator
The battery indicator displays the remaining battery life. See the battery operation
section for detailed information. NOTE: The battery Indicator will be disabled
when using an external power supply.
Software Number and Revision display
Pressing and holding the REWEIGH button for 3 seconds will perform a display
test. The software number, “Su179”, and the revision, “r 3.2” (or higher), are
displayed first. After displaying the revision, the scale enters a “switch test” mode
where the keys can be pressed to verify their operation. If no keys are pressed
for 10 seconds, the scale will perform a display test and return to its normal mode
of operation.

Section 6. Data Communications
RS-232 Communications Port
The indicator is equipped with an RS-232 communications port. The RS-232
connection is located on the back of the indicator behind the top access cover.
An optional RS-232 cable is available. Insert the phone style connector into the
receptacle on the indicator housing and connect the 9-pin connector to your
computer or printer.
Note: This option may reduce battery life.
Basic understanding of RS-232 data communications is needed when setting up
the indicator to communicate with a printer or PC. When setting up an RS-232
communications system, there are two concerns which affect the configuration of
that system. These are:
Baud Rate
Data Bits and Parity
The baud rate determines how fast the data is sent from the scale. The sending
and receiving units must be set to the same baud settings. Refer to the For.
parameter for details.
The indicator’s data bits, parity and stop bits are set when configuring the For.
parameter. The receiving units must match the scale setting for proper
communication.
USB Communications Port
The indicator is equipped with a USB communications port. The USB
connection is located on the back of the indicator behind the top access cover.
An optional USB cable is available. Follow the instructions included with the
option to install all necessary drivers.
Once the USB drivers are installed on your PC, insert the USB connector into the
receptacle on the indicator and connect the other end of the cable to your
computer.
