Problem: scale shuts off by itself
Fix:
Check the battery holder terminals. They may be bent and not making solid
contact. If the scale turns off immediately after you take your finger off the
button, there may be defective power circuitry or a bad keypad.
Problem: scale “locks up”
Fix:
The microprocessor (U1) may need to be replaced. The microprocessor support
circuitry could also be bad.
Problem: weights jump or drift
Fix:
Try increasing the sample rate as described in the calibration section (pg 13). If
this does not help, the problem could be a bad load cell, defective amplifier (U5),
bad A/D chip (U6), or contamination on the circuit board.
