Introduction 1
1.0 Introduction
The RL-650 Series Neonatal Scale provides precise weighing of infants and neonates. The scale is equipped with
Motiontrap™, a special motion sensing weighing technology, which compensates for involuntary movement caused
by an active infant. The infant’s weight can be displayed in pounds/ounces or in kilograms/grams. The weight is
displayed until reweighing is performed or until the scale zeros out.
There are precautions that must be taken to prevent injury to the baby and damage to the scale. See Section 1.2 on
page 2.
Follow all instructions for installation and usage, included in this manual. The manufacturer is not responsible for
any damage or injury from incorrect operation or manipulation by the user.
Manuals can be viewed and downloaded from the Rice Lake Weighing Systems website at
www.ricelake.com

Safety Signal Definitions:
Indicates an imminently hazardous situation that, if not avoided, will result in death or serious injury.
Includes hazards that are exposed when guards are removed.
Indicates a potentially hazardous situation that, if not avoided could result in serious injury or death.
Includes hazards that are exposed when guards are removed.
Indicates a potentially hazardous situation that, if not avoided, could result in minor or moderate injury.
Indicates information about procedures that, if not observed, could result in damage to equipment or
corruption to and loss of data.
General Safety
Do not operate or work on this equipment unless this manual has been read and all instructions are
understood. Failure to follow the instructions or heed the warnings could result in injury or death.
Contact any Rice Lake Weighing Systems dealer for replacement manuals.
Failure to heed may result in serious injury or death.
Never leave an infant unattended on the scale
Ensure weighing tray is secured to scale base prior to placing a neonate/infant on weighing tray.
Do not transport the scale with the infant in the weighing tray.
Do not use around flammable materials.
Scale should only be used to determine weight of babies/neonates. It is not intended to diagnose, prevent and monitor
diseases.
To avoid cross contamination, the scale plate must be cleaned after each use. Avoid direct skin contact during weighing.
Use disposable paper towels or bed pads for each scale.
Operation at other voltages than specified could damage the equipment.
Rice Lake Weighing Systems offers optional adapters. Utilizing an adapter not supplied by us voids all warranties.
Do not modify this scale without authorization of the manufacturer.
Do not drop the scale or subject it to violent shocks.
For accurate weighing, the scale must be placed on a flat, stable surface.
For accurate weighing, verify proper operation according to the procedure described in this manual before each use.
1.3 Information Symbols
The International Electro-Technical Commission (IEC) has established a set of symbols for medical electrical
equipment, which classify a connection or warning as a potential hazard.
The classification of symbols is as follows.
Type BF (Body Protected)
This means that the unit complies with the specified requirements of this standard to provide protection against
electric shock.
Waste Electrical and Electronic Equipment (WEEE).
The device can be sent back to the manufacturer for recycling or proper disposal. Alternatively, the device must
be disposed in accordance with national laws when scale is no longer used.

5.0 RS-232 Communication
The scale comes with an RS-232 port which 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
System. Figure 5-1 shows where the RS-232 connection is.
The RS-232 parameters are 9600 baud (selectable in the programming mode), 8 data bits, 1 stop bit, no parity and
no handshaking.
The method to access weight data from the computer is:
• Pushbutton keypad print - Done by pressing and holding the REWEIGH key.
5.1 Pushbutton Keypad Print
With a stable, in-range weight, press and hold the REWEIGH key for at least three seconds. Note that if the scale
does not beep after five seconds, then release the button as the weight was either in motion, or out of range. The
print will show on the display when it is transmitting data.
If displaying weight, the scale will send out the following 21 character string:
xxxxxxxxx<SP>uu<SP>mmmmm<SP><CR><LF>
Where:
xxxxxxxxx is the weight with decimal point and (-) neg sign, if negative uu is the unit (lb or kg).
mmmmm is the mode (gross or net)
Examples:
-10 Lb net = <SP><SP><SP><SP>-10.0<SP>lb<SP><SP>Net<SP><SP><SP><CR><LF>
10 Lb gross = <SP><SP><SP><SP><SP>-10.0<SP>lb<SP>Gross<SP><CR><LF>
5.2 USB Connection
The RL-650 has the capability of connecting to a PC using a USB connection and a USB cable. That connection
location is shown in Figure 5-1.
Figure 5-1. USB Connection Port and RS-232 Connection Port
Connecting software and downloads should be addressed by an IT professional, and can vary depending on the
