Faulty electrical outlet Use a different electrical outlet.
Bad power supply Replace adaptor.
Questionable weight or the scale
does not zero External object is interfering with the
scale Remove the interfering object from the scale.
Display did not show 0.0 before
weighing Zero the scale and begin the weighing process
again.
Scale is not placed on a level floor Ensure the scale is level and begin the weighing

Improper tare Place the tare item on the scale. Once the weight
of the item is displayed, press TARE.
The display shows a STOP message The load on the scale exceeds the
capacity of the scale Remove the excess weight and use the scale
according to manufacture’s specs.
The display shows LO Bat message The battery is low Recharge the battery.
The display shows Err message as
detailed below
Err 2 Low saturation state (low A/D) The load cell is not connected properly. Check
the cables and mechanical connections. If the
problem persists, replace the set of load cells.
Err 3 High saturation state (high A/D) See Err 2
Err 6 Unstable weight. Cannot calibrate Check the load cells’ mechanical surroundings
and see that nothing touches them and that the
cables are properly welded.
Err 7 Mathematical error; division by zero.
Cannot calculate calibration factor. This error will show when trying to calibrate the
unit with no calibration weight on the unit.
Calibration or configuration settings
are messed up Pushed the wrong keys Reset to factory defaults. See Page 9 for
instructions.
The display shows a Con En message The configuration jumper is not in

9.1 Test Mode
The test mode menu is a special mode used for checking three very important parameters which are useful in
knowing the system’s state and for troubleshooting. The configuration/calibration jumper must be removed
before you can enter this mode (see Figure 4-1) and power must be off.
To access the test mode parameter, press and hold the
REWEIGH
+
On-Off/Zero
keys simultaneously until middle
arrows appear in the display.
The test mode has three parameters. They are:
• Weighing
• Internal count
• Battery indication.
Alternating between the parameters is performed by pressing the
REWEIGH
key.
Press the
Kg-Lb
key to zero the scale while displaying weight (
