Introduction

The RL-650 Series Neonatal Scale provides precise weighing of infants and neonates. The scale is equipped with MotiontrapTM, 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 and additional resources are available from the Rice Lake Weighing Systems website at www.ricelake.com Warranty information can be found on the website at www.ricelake.com/warranties

2. Tip the unit on its side to access the battery chamber.
   
   Do not tip the scale completely up side down, this could damage the load cells.
3. Remove four screws from the cover plate. Cover plate will come off at the same time. Retain for re-installation.
4. Insert six batteries into the battery chamber according to the diagram inside.
5. Replace the cover plate and secure with screws.
6. Set the scale up right on a flat surface.

Battery Status

If when using AC adapter or USB power, the battery icon is off.
When using battery or USB power supply, the back-light power is reduced to 60%.

AC Power Supply – Optional

An optional 120 VAC or 230 VAC adapter is available from Rice Lake Weighing Systems. To operate the unit using the AC adapter, plug the cable into the back of the scale and the AC adapter plug into a power source.

Utilizing an adapter not supplied by Rice Lake voids all warranties.

Use the following steps to enter into the calibration mode and calibrate the unit.

1. Press and hold and then press until ID is displayed.
2. Using a non-conductive instrument, press the setup switch located under the unit. PROG displays.
   
3. Press the left arrow until CALIB is displayed.
4. Press .
5. Use or to select 20 lb or 10 kg.
   If using a different weight value other than those listed in Step 5, press again and the far right digit flashes.
   Press the up or down arrows to change the weight value. The left arrow moves to the next digit on the left, allowing changes to the value.
6. Press to save that weight value. CLEAR displays.
7. Make sure the platter is empty and press . displays.
8. PUT is displayed. Put the entered value (ie: 20 lb) onto the platter. displays.
9. Press . The scale calibrates that weight. Once calibrated, SAVE is displayed.
10. Press . The scale displays DONE.
11. Press so goes back to DONE, then press . The scale reboots and returns to weigh mode.

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.

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>

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.

Connecting software and downloads should be addressed by an IT professional, and can vary depending on the computer platform used. Basic information on USB driver installation using Windows® is described in the following steps and serves only as an example.

A USB driver can be downloaded from the Rice Lake Weighing Systems website at: https://www.ricelake.com/resources/software-firmware

1. Search for Titanium USB Driver.
   
2. Click on Download to open and download the driver to a local computer.
3. When the USB cable is connected to the indicator and the scale is turned on, a display prompts to navigate through the software install process.
   
4. Select No, not this time, and then click Next.
5. Select Install the software automatically, then select Next. A file transfer screen displays as the file downloads and installs to the computer.
6. Click on Finish when the completion screen displays.
7. To verify the installation, view the driver by looking at the device manager of the system.
   
8. To configure a printer using the USB driver, open the software driver Parpar in the device manager (Figure 5-4). The port assigned to that driver is displayed.
9. Ensure the USB cable is properly connected and the unit is on.
10. Open and connect a terminal emulation program, such as Hyperterminal, via the USB driver. Select the port assigned to the software driver Parpar to establish a port. The terminal emulation program is necessary to view information transmitted from the indicator to the PC.
11. Press . The following example tickets print.
    

A single print ticket has four spaces after the “patient weight” and only one space between weight and lb in the examples shown above. Then seven after.

Maintenance

The following section provides instructions for maintaining and cleaning the RL-650 Series neonatal scale. Maintenance operations other than those described in this section should be performed by qualified service personnel.

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, abuse, etc.
2. Inspect the condition of the optional AC adapter for cord cracking or fraying, or for broken or bent prongs.

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.
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.

Do not immerse the scale into cleaning or other liquid solutions.
Do not use Isopropyl alcohol or other solutions to clean the display surface.
