3.1 Unpacking Your Scale
Place the unopened box in an open area that has ample room for unpacking the scale.
Parts contained in the shipping box include:
• The scale which includes the scale base and attached column
• O peration manual
• C D containing USB driver
•Height rod
• W hite box labeled Parts Inside which contains the following:
• Wheels (2)
• Wheel hinge (1)
• P an head screws (8)
• AA batteries (6)
All component parts have been wrapped in plastic. Remove the plastic and set aside.
3.2 Repacking
If the Rice Lake Digital Physician Scale must be returned for modification, calibration or repair, it must be
properly packed with sufficient packing materials. Whenever possible, use the original carton when shipping the
scale back.
Damage caused by improper packaging is not covered by the warranty.
3.3 Setting Up Your Scale
Use the following steps to set up the Rice Lake Digital Physician Scale.
Tools needed for setup include:
• Phillips head screwdriver
Use the following steps to set up the scale.
Move the scale into the area where the weighing process will occur. Place the scale on a hard, level surface for
the most accurate weighments.
1. Locate the operator’s manual from inside the box and set aside as it will provide instructions on the
proper scale removal and set up.
2. Carefully lift the scale out of the packaging material; lift it out by the scale base.
The scale base and scale column are connected by cable and require great care when
removing from the box so that the cabling does not get damaged.
Figure 3-1. Cabling Connecting the Scale Platform and Scale Column
Rice Lake Digital Physician Scale — Scale Assembly 3
Page 8
3. Gently thread loose cabling through the top of the scale column to eliminate any excess cable at the
bottom of the column. This will eliminate the chance of pinching the cable as the column is being
connected to the scale base.
4. Attach the scale column to the base as shown in Figure 3-2 making sure not to pinch the cable.
Figure 3-2. Attaching the Scale Column to the Scale Base
5. Using the enclosed screws, attach the column to the scale base as shown in Figure 3-3.

Attach the wheel assembly to the scale prior to connecting the second column. To attach the wheels, use the
following steps.
1. Attach the two wheels to the wheel assembly rod, as shown in Figure 3-4.
Figure 3-4. Attach Wheel Assembly
2. Attach the wheel assembly to the scale using a Phillips head screw and tighten with a screwdriver.
Attach Second Column to First Column
Once the wheel assembly is attached, finish the scale assembly using the following steps.
Ensure that the cable is extending through the top of the lower column so that it can be plugged into the
second (upper) column.
3. Once the cable is connected, insert and slide the upper column onto the lower column as shown in
Figure 3-6, making sure that the screw holes are lined up and that the cable does not get pinched.
4. Insert two screws and tighten using a Phillips head screwdriver.

Height Rod Installation
Use the following steps to install the height rod assembly.
1. The height rod comes in two pieces. Connect the two pieces together.
2. Slide the assembled height rod from the top of the column in the slot located on the front of the scale as
shown in
Figure 3-7.
Figure 3-7. Height Rod Assembly
3. T o use the height rod, pull up on the height rod using the plastic cap located at the top of the height rod as
shown in Figure 3-7.
4. Swing the height adjustment lever into a horizontal position according to the person to be measured. The
person being measured needs to stand straight with the height adjustment lever just touching the top of
the person’s head.
Inserting Batteries
The six AA batteries that come with the scale offer an average of 25 hours of continuous use.
To install the batteries,
1. Open the battery chamber cover by loosening the thumb screw.
2. Insert batteries as shown in Figure 3-8.

7.0 RS-232 Communication
The scale comes with an RS-232 port that enables weight data to be transmitted to other equipment, such as a
computer or printer. The RS-232 cable with DB-9 connector (PN 100719) is available from Rice Lake Weighing
Systems.
The RS-232 parameters are 9600 baud (selectable in the programming mode), 8 data bits, 1 stop bit, no parity
and no handshaking.
There are three methods of communication:
7.1 Push-Button Keypad Print
With a stable, in-range weight, press and hold the LB/KG/Print key for at least three seconds, or until the scale
displays
either in motion, or out of range.
xxxxxxxxx<SP>uu<SP>mmmmm<SP><CR><LF>
Where:
Example:
Figure 3-9 on page 7 shows where the RS-232 connection is.
• Pushbutton keypad print
• Escape protocol
• Maintenance protocol
PRINT. Note that if the scale does not beep after five seconds, then release the button as the weight was
• If displaying weight and not BMI, the scale will send out the following 21 character string:
xxxxxxxxx is the weight with decimal point and " - " sign, if negative uu is the unit (lb or kg).
mmmmm is the mode (gross or net)
60.1 KG= <PATIENT><SP><WEIGHT><SP>-60.1<SP>KG<SP><CR><LF>
• In BMI mode (displaying the BMI value), the scale will send out the following data:
PATIENT WEIGHT 60.1 KG
PATIENT HEIGHT 170.0 CM
PATIENT BMI 20.8
Example in KG:
<PATIENT><SP><WEIGHT><SP>-60.1<SP>KG<SP><CR><LF>
<PATIENT><SP><HEIGHT><SP>-170.0<SP>CM<SP><CR><LF>
<PATIENT><SP><B><SP><M><SP><I><SP><SP><SP><20.8<SP><SP><SP><SP><CR><LF>
Example in LB:
<PATIENT><SP><WEIGHT><SP>132.4<SP>LB<SP><CR><LF>
<PATIENT><SP><HEIGHT><SP>-5-07.5<SP>FT<SP><CR><LF>
<PATIENT><SP><B><SP><M><SP><I><SP><SP><SP><20.4<SP><SP><SP><SP><CR><LF>
In case of under weight or over weight, the word Under or Over will be sent correspondingly.

7.2 Communication Protocols
The RL150 has two communication protocols, escape and maintenance protocol.
7.2.1 Escape Protocol
An escape protocol is where the escape (0X1B or ASCII 27) is used to indicate that there is a command
following. On the PC side there must be a listener created by the vendor that will interpret this protocol. This
listener must also take care of all the issues regarding data integrity, etc. to make sure that the data that was sent
and received is valid.
Two examples include:
• Scale initiated communication
• PC initiated communication
Table 7-1 is what can be sent across communications lines.
PC Initiated ESC Value
Request current values/settings R
Diagnostics A
Send scale control messages C
PC Initiated ESC Value

Table 7-2 lists the ESC characters that will be used.

Reading R R This tells the PC that the scale is sending a reading. Immediately
Weight W Wnnn.n This is the patient weight (ie: W02000 means 200.0). If the scale is

9.0 Maintenance
The following section provides instructions for maintaining and cleaning the Rice Lake line of scales.
Maintenance operations other than those described in this section should be performed by qualified service
personnel.
9.1 Basic Maintenance
Before the first use of the scale and after periods of non-use, check the scale for proper operation and function. If
the scale does not operate correctly, contact qualified service personnel.
Go through the following steps for basic maintenance.
1. Check the overall appearance of the entire scale for any obvious signs of damage.
2. Inspect the condition of the AC adaptor for cord cracking or fraying or for broken or bent prongs.
9.2 Cleaning
Proper care and cleaning is essential to ensure a long life of accurate and effective operation. Before beginning
the cleaning process, disconnect the scale from the AC power source.
1. Clean all external surfaces with a clean, damp cloth or tissue. Mild soap and water solution may be used.
Dry with a clean soft cloth.
2. Do not immerse the scale in cleaning or other liquid solutions.
3. Do not use isopropyl alcohol or other solutions to clean the display surface.
