the lb / kg button to toggle up between functions.
2. If no buttons are pressed, the system will remain in diagnostic mode for approximately 5 minutes before
turning off.

Displaying Individual Load Cell Outputs:
After entering diagnostics, press the lb / kg button to toggle up between the individual load cell readings.
15−45 lbs is a typical reading for an empty stretcher. Anything drastically outside that range indicates a prob-
lem with that load cell. Before replacing a load cell, verify the cable to the individual load cell is properly con-
nected. A reading of 497.5 lbs indicates the load cell cable is disconnected or the load cell has been damaged.
If the system detects a defective load cell, the display will read Test then Err. Verify the load cell cable is proper-
ly connected. If it is, replace the load cell. When the load cell is functioning properly, the display will read
Test then Good. The scale will operate normally.
Battery Voltage:
After entering diagnostics, press the lb / kg button to toggle up to the BATT function. If the battery voltage
reading is below 5.1, change the batteries (see page 26). The display will read LO BATT and the battery icon
will be flashing at this voltage.
