TROUBLESHOOTING
The following describes conditions you may encounter while operating this scale. Instructions
are provide to help you correct the problem. If you are still unable to resume normal operating
functions, please contact your nearest scale technician or our Technical Support Department.
Negative Weight Display
The scale will display a negative weight when the scale base has been
emptied or partially emptied without re-zeroing the scale. To re-zero the
scale, press the ON/ZERO key, wait for the display to read zero, and start
the procedure again.
No Weight Displayed
Is the power supply cable plugged into the PZ3000 display? Is the AC power adapter plugged
into a wall receptacle? Check the wall receptacle for proper AC power. Try another electrical
appliance in the same receptacle. Does it work? Check the circuit breaker. Has there been a
power failure of any kind? Are the batteries discharged?
Incorrect Weight Reading
Insure that the scale platform isn't touching an adjacent object. The display will show an
incorrect weight when there is a product buildup under the platter. Clean the platter and place on
the scale platform securely. Test with a known amount of weight to see if the correct weight is
displayed. Have proper operation procedures been followed? If problem persists, the scale may
need re-calibration. Contact your scale serviceman.
