SCALE SYSTEM DIAGNOSTICS AND CALIBRATION
Diagnostic Mode Functions:
1. ANGLE CALIBRATE − This may be required in the field to recalibrate the scale. Calibrate using 50
pounds.
2. DISP. CORNER LBS − This function displays the individual corner weights in pounds for each load cell
assembly and can be used to isolate a defective load cell.
3. DISP. CORNER CTS − This function displays the individual corner weights in counts for each load cell
assembly and can be used to isolate a defective load cell.
4. DISPLAY FACTORS – This function is used to see the scale calibration factors. This can be used to
diagnose a bad scale calibration.
5. DISPLAY AVERAGES − This function is used to see the average weight in pounds each load cell has
experienced.
6. DISPLAY MAXIMUMS − This function is used to see the maximum weight each load cell has experi-
enced.
7. CLEAR STATISTICS − This function is used to clear the averages and maximums.
8. INIT TO DEFAULTS − This function is used to reset the scale factors back to defaults.
9. VIEW ERROR LOG − This function can be used to see a log of scale errors and the time they occurred.
10. LOCK/UNLOCK UNITS − This function can be used to lock out the ability to change weight units.
11. PICK EXIT ALARM − This function can be used to select a different bed exit alarm tone.
12. SOFTWARE CONFIG − This function can be used to see what the bed configuration is.
13. SOFTWARE VERSION − This function can be used to see what software version it is.
14. CALIBRATE SCALE − This is the old scale calibration routine with 200 pounds. Only there for backup
purposes.
15. EXIT DIAGNOSTIC − This function will give you the ability to exit the diagnostic mode and go into scale
mode.
Diagnostic Mode:
NOTE
It requires two people to enable the diagnostic mode for the scale system.
1. To enter diagnostic mode, unplug the bed’s power cord from the wall socket.
2. Press and hold down the LBS/KGS button.
3. While still holding the LBS/KGS button, plug the bed’s power cord into the wall socket.
4. After two seconds, release the LBS/KGS button. The scale monitor should read “ANGLE CALIBRATE”.
The diagnostic mode is now active.
Displaying Individual Load Cell Outputs:
A defective load cell can be detected by entering diagnostics and displaying individual load cell outputs.
1. Enter the diagnostic mode. The LCD will display “ANGLE CALIBRATE” when the diagnostic mode is
activated.
2. Repeatedly press and release the up or down arrow button (ZERO or SCALE ON/OFF) until the LCD
displays “DISPLAY CORNER CTS”.
3. Press and release the ENTER button (LBS/KGS). The LCD should display “ƜƝ SELECT CORNER”.
