Displaying Individual Load Cell Outputs:
A faulty load cell can be detected by entering diagnostics and displaying individual load cell outputs.
1. Enter the diagnostic mode. The scale monitor will display DOWNLOAD BARCODE when the diagnostic
mode is active.
2. Press and release LBS/KGS until the scale monitor displays DISPLAY CORNER.
3. Press and release WEIGHT SYSTEM ON. The scale monitor should display PICK CORNER NOW.
4. Press and release the position key that corresponds with the load cell to be checked. The scale monitor
should display XX=NNN.N. ”XX” represents the initials of the selected corner, i.e. H/R will be displayed
for the patient’s head end, right side. ”NNN.N” represents the actual weight load on the load cell.
5. Repeat step four for each corner. Head end weight readings will normally be lower than foot end weights.
Weight readings should be constant. A jumpy, drifting 000.0 or 999.9 weight indicates a problem with
the selected load cell assembly or load cell cable.
6. When all the load cell outputs have been checked, press and release WEIGHT SYSTEM ON.
7. Press and release LBS/KGS until the scale monitor displays QUIT/SAVE.
8. Press and release WEIGHT SYSTEM ON. The scale monitor should shut off after one second.
