20-2. Error Codes
Display Error code Description
EC, E11
Stability error
The balance can not stabilize due to an environmental problem. Prevent
vibration, drafts, temperature changes, static electricity and magnetic
fields. Refer to "3. Precautions" for details on the operating environment
and "7. Response Adjustment" about adapting the balance to the
environment. To return to the weighing mode, press the
CAL key.
Out of range error
The value entered is beyond the settable range. Re-enter the value.
EC, E17
Internal mass error (Only for the HR-AZ series)
The internal mass application mechanism does not function properly.
Perform the weighing operation from the beginning again.
EC, E20
Calibration weight error
The calibration weight is too heavy. Confirm that the weighing pan is
properly installed. Confirm the calibration weight value.
Press the
CAL key to return to the weighing mode.
EC, E21
Calibration weight error
The calibration weight is too light. Confirm that the weighing pan is
properly installed. Confirm the calibration weight value.
Press the
CAL key to return to the weighing mode.
Overload error
A sample beyond the balance weighing capacity has been placed on
the pan. Remove the sample from the pan.
Weighing pan error
The weight value is too light. Confirm that the weighing pan and pan
support are properly installed. Press the ON:OFF key two times to
return to the weighing mode. If the error still persists, calibrate the
balance.
Sample mass error
The balance can not store the sample for the counting mode or for the
percent mode because it is too light. Use a sample that is heavier.
Unit mass error
The sample unit mass for the counting mode is too light. Storing and
using it for counting will cause a counting error. Add samples to reach
the specified number and press the
PRINT key.
Pressing the PRINT key without adding samples will shift the balance
to the counting mode. But, to acquire accurate weighing, be sure to add
samples.
Balance internal error
If this error appears persistently, contact the local A&D dealer.
Battery error for clock
The back-up battery power for the clock was lost completely. After
pressing one of the keys, adjust the date and time. Even if the back-up
battery power for the clock was lost and the balance is on or in the
standby state, the balance performance will be normal. When this error
appears frequently, repair is required.
