Introduction

The 650-10-1 Neonatal Scale provides precise weighing of infants and newborns. The scale is equipped with Motion trap special motion sensing weighing technology, which  compensates for involuntary movement caused by an active infant. The infant’s weight can be displayed in pounds and ounces or kilograms and grams. The weight is  displayed until reweighing is performed or until the scale zeros out.
Manuals and additional resources are available on the Rice Lake Weighing Systems website at www.ricelake.com Warranty information can be found on the website at www.ricelake.com/warranties

The 650-10-1 Neonatal Scale comes with four parts:

• Weighing tray
• Base assembly
• USB and RS-232 cable
• Six AA LiFeS2 lithium iron disulfide batteries

Remove each part to be assembled from the carton and unwrap the packing material carefully to prevent scratching the parts.
1.4.2 Repacking
If the 650-10-1 Neonatal Scale must be returned for any reason, it must be properly packed with sufficient packing materials.
Whenever possible, use the original carton when shipping the scale back.
**IMPORTANT:** Damage caused from improper packaging is not covered by the warranty.

1.5 Setting up the Scale
To set up the scale, select a sturdy, flat surface on which to place the scale.
1.5.1 Inserting Batteries
The six AA LiFeS2 lithium iron disulfide batteries that come with the scale offer an average of 25 hours of continuous use. To install the batteries:

1. Tip the unit to reveal the battery chamber plate location.
   IMPORTANT: Do not tip the scale completely up side down as this could damage the load cells.

2. Using a small Phillips head screwdriver, unscrew the four screws from the battery chamber cover and set aside.

3. Insert the six batteries into the battery chamber.

4. Close the battery chamber and tighten the screws.

5. Turn the unit right side up on a flat surface.
   **** NOTE: When using an external power supply, or when a USB power supply is connected, the battery icon on the display is turned off. When using batteries, the  backlight power is reduced to 60 percent.

6. Remove the two angular transport tabs from the scale as shown in Figure 1-1.

7. Rotate the adjustable feet located under the scale base to level the scale.

8. Attach the weighing tray to the base assembly.

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 a DB-9  connector (PN 100719) is available from Rice Lake Weighing Systems. Figure 3-1 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.
There are three methods to access weight data from a computer:

• Pushbutton keypad print – Done by pressing and holding the Reweigh key.
• Standard remote protocol – See 650-10-1 Neonatal Scale Technical Manual (PN 172982)
• Escape protocol – See 650-10-1 Neonatal Scale Technical Manual (PN 172982)

3.1 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:
xxxxxxxxxuumamma
Where: xxxxxxxxx is the weight with decimal point and – sign, if negative uu is the unit (pound or kilogram). momma is the mode (gross or net)
Examples: -10 lb net =
