15-2. Error Codes
Display Error code Description
EC,E11
Stability error
The balance can not stabilize due to an environmental
problem. Check around the pan. Refer to "3. Precautions".
Prevent vibration, drafts, temperature changes, static
electricity and magnetic fields, from influencing the balance.
To return to the weighing mode, press the
CAL key.
Out of the setting range
The data to be stored is out of the setting range.
EC,E16
Internal mass error
Applying the internal mass does not yield a change in the
weight value as specified.
Confirm that there is nothing on the pan and perform the
weighing operation from the beginning again.
EC,E17
Internal mass error
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 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 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 is properly installed and
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 larger sample.
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.
