3. Pull down the wire out of post pipe and insert the post pipe to the post
bracket. (Refer to fig. 1)
4. Fasten the post pipe with two bolts. (Refer to fig. 1)
5, A long bolt should be connected to the upper side.
6. Insert the wire to the post pipe. (Refer to fig. 2, 3)
7. If the scale is not properly level, please adjust 4 leg(adjusting bolt) at the
bottom of the scale so as to center the bubble of the leveling gauge.
Note : Place the scale on a flat and stable surface.
Inside the indicated circle.

ErrorsinWeighingMode
Err 01
Cause
The Indicator can't be initialized due to platform shaking.
Management
Put the platform on a flat place without shaking and power on.
Err 02
Cause
The load cell is connected wrongly or A/D conversion part has a fault.
Management
Check that the load cell is well connected with main unit.
Err 03
Cause
The calibration isn't executed or the data of internal memory is lost due to
a electrical shock.
Management
Perform the required specification again in setting mode.
Err 09 (Zero Key)
Cause
The current weight exceeds zero range.
Err 10
Cause
The specified TARE weight exceeds the maximum capacity.
Management
Set the TARE weight lower than maximum capacity.
Or set the maximum capacity higher than the desired TARE weight in
calibration menu and perform the calibration again.
ERROR MESSAGE DESCRIPTION & MANAGEMENT Err 13 (Zero Range with power on)
Cause
The initial zero range exceeds above 10% of maximum capacity.
Management
Check the load cell state.
Over
Cause
Too heavy object is put on platform so that it may exceed the
maximum capacity.
Management
Never put the weight exceeding the maximum capacity.
If the load cell is damaged, replace the load cell
ErrorsinCountMode
Err 61
Cause
The count unit weight and sample weight are set too high.
Management
Set the count unit weight low or the count sample quantity high.
Err 62
Cause
The count unit weight and sample weight are set too low.
Management
Set the count unit weight high or the count sample quantity low.
