OVER ERROR
- The weight of the sample to be weighed is in
excess of the maximum capacity.
- Split the sample into several pieces and
weigh them.
- Replace the tare with a lighter one.
- The addition result has exceeded the maximum
number of displayable digits.
- Clear the calculation result, and then re-
execute the addition/computation while
being careful of the display digit.
UNDER ERROR The negative load is below the lower limit.
-
-
Improper setting of the weighing pan or
pan base is suspected.
Check for contact with other object.
Use the dedicated weighing pan and pan
base only.
DISPLAY
ERROR
The addition result has exceeded the maximum
display digit.
Clear the calculation result, and then re-
execute the addition/computation while
being careful of the display digit.
LOWER ERROR The unit/reference weight in
Counting/Percentage mode is below the lower
limit.
Choose the samples of which unit
weight/reference weight is larger than the
lower limit.

ERR099
System error
Record the error code and notify the store
where you purchased the product.
ERR703
- The operation key was pressed at the time of
starting from the standby status.
If the error message is displayed nevertheless
the operation key wasn’t pressed, there is
something wrong with the hardware.
Do not press the operation key while the
scale is in the process of starting from the
standby status.
ERR705
Initial zero adjustment error.
The initial zero adjustment was not completed in
the process of starting from the standby status
because of the unstable load.
-
-
Improper setting of the weighing pan or
pan base is suspected.
Check for contact with other object.
- Check for any wind or vibration.
ERR706
The load is out of the initial zero adjustment
range.
- Do not put any load on the weighing pan
at the power-on of the scale.
ERR709
ERR710
ERR711
-
-
The load is unstable at the zero adjustment/tare
subtraction.
Span adjustment time-out error.
-
-
Improper setting of the weighing pan or
pan base is suspected.
Check for contact with other object.
- Check for any wind or vibration.
ERR717

-
The mass of the external calibration weight is
more than 1% differ from:
the designated mass at the span adjustment; or
the maximum capacity (Max) at the span test.
Check the calibration value of the weight
and use the proper calibration weight.
ERR718
The mass of the calibration weight is under 50%
of the maximum capacity at “span adjustment”
or “calibration of the internal weight” by external
calibration weight.
Use the calibration weight of which weight
is equal to the maximum capacity.
ERR719
The adjust value by “span adjustment” is over
1% of the maximum capacity.
- Execute <637 REF CAL RESTORE>, then
execute <636 REF CAL>.
- Check the mass of the weight used for the
span adjustment by external weight.
ERR722
- Tare key is pressed during the Preset tare
operation.
Do not press the Tare key during the
Preset tare operation.
ERR723
Out of Zero adjustment range (1.5% of the
maximum capacity)
Make sure nothing on the weighing pan
while executing zero adjustment.
ERR724
Out of Tare subtraction range (0g to the
maximum capacity)
Chose the tare of which weight is within
the tare subtraction range.
