9. BATTERY OPERATION
e Medical Scale can be operated from the battery if desired. e
batterylifeis12hours(backlight)and22hours(withoutback-
light).
When the battery needs charging a symbol on the weight display
will turn on. e battery should be charged when the symbol is on.
e scale will still operate for about several minutes aer which it
will automatically switch o to protect the battery.
To charge the battery simply plug into the main power. e scale
does not need to be turned on.
e battery should be charged for 12 hours for full capacity.
Just under the quantity display is an LED to indicate the status of
battery charging. When the scale is plugged into the main power
the internal battery will charge. If the LED is green the battery has
a full charge. If it is Red the battery is nearly discharged and blue
indicates the battery is being charged.
As the battery is used it may fail to hold a full charge. If the battery
life becomes unacceptable then contact your distributor.
Note: useless battery should be recycled, not thrown away
in every day trash or go to landlls.

TO DO SO COULD RESULT IN BODILY
HARM OR DAMAGE THE UNIT.
CAUTION
10. MAINTENENCE
10.1. General
If the scale does not operate properly, nd out the problem if possible.
Determine whether the problem is constant or alternating. Be aware that
problems can be caused by mechanical or electrical inuences.
Checkthefollowing.
• Water
• Corrosive materials
• Vibrations or temperature or wind
• Physical damage
Checkthescalecablesfordamage,andcheckallconnectionsand
connecters for any loose contact or incorrect connection
• Permit only qualied persons to service the instrument
• Before connecting or disconnecting any components,
remove the power.
• Failure to observe these precautions may cause bodily
harm or damage to or destruction of the equipment.

Cleaning
• Disconnect the power before cleaning.
• Use a cloth with mild suds and light cleaning agents.
• Makesurethatuidisnotabletogetintothescale.
• Use a clean and so cloth for rub o.
10.2. Error Codes
Error Code Description POSSIBLE CAUSES
Err 4 Zero range exceeded. • Goods on the platform
• Overload, when zeroing the
scale.
• Improper calibration
• Load cell problem
• PCB problem
Err 6 A/D Count out of the
range
• Platform not installed
• Load cell problem
• PCB problem
10.3. Determine the Problem
Determine whether the problem is in the PCB or the Load Cell
• Remove power from the system, and disconnect the load cell
connection from the PCB
• Connect the PCB to a load cell simulator
• Reapply power and test the PCB
• If problem goes away, its source is probably in the Load cell.
