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.
