GENERAL
This section provides instructions for maintenance, cleaning, troubleshooting and operator replaceable parts for the Physician Digital Scale.
Maintenance operations other than those described in this section should be performed by qualified service personnel.
.
MAINTENANCE
.
Before first use and after periods of non-use, check the scale for proper operation and function. If the scale does not operate correctly, refer
to qualified service personnel.
1. Check overall appearance of the total scale for any obvious damage, abuse, etc.
2. Inspect condition of AC adapter cord and prongs, replace if needed.
CLEANING
Proper care and cleaning is essential to ensure a long life of accurate and effective operation. 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 into cleaning or other liquid solution.
3. Do not use Isopropyl Alcohol or other solutions to clean the display surface.
.
TROUBLESHOOTING
.
Refer to the following instructions to check and correct any failure before contacting service personnel.
SYMPTON
POSSIBLE CAUSE
CORRECTIVE ACTION
Scale does not turn on
1. Dead Battery
2. Faulty electrical outlet
3. Bad Power Supply (Check LED
light at back of display module to
determine if adapter cord is
working)
1. Replace
batteries
2. Use a different outlet
3. Replace adapter
Questionable weight or the
scale does not zero
1. External object interfering with
the scale
2. The display did not show ‘000.00
before weighing
3. Scale is not place on a level ˛floor
4. Scale is out of calibration
1. Remove interfering object
from the scale
2. Ask the patient to get off the
scale, zero the scale and begin
weighing process again
3. Place the scale on a level floor
and begin weighing process
again
4. Check weight with known
weight value
The display shows “OVER”
The load on the scale exceeds the capacity
(600lbs)
Remove the excess weight and use the
scale according to its limits
The display shows “LO Bat”
message
The batteries are dead
Replace batteries according to instructions
ERROR LIST
ERROR
NO.
DEFINITION CHECK/REPLACE
Err 1
Mathematical mistake; division by zero. Cannot
calculate calibration factor
Will show when trying to calibrate with no calibration
weight
Err 2
Weight loaded too low. Cannot calibrate
While in calibration procedure add more weight in
load mode
Err 3
Unstable weight. Cannot calibrate
Check the load cells mechanical surroundings and see
nothing touches them and the cables are well
connected
Err 5
Calibration disabled
Toggle the calibration switch to enable
Err 6
High saturation state (high A/D)
The load cell is not connected correctly. Check the
connection, cables, and mechanical connection. If
the problem persists, replace the set of load cells
Err 7
Low saturation state (low A/D)
See Err 6
