Test Mode
The test mode menu is a special mode used for checking four very important parameters which are useful in
knowing the system’s state and for troubleshooting. Entry into this mode is possible only when the scale is turned
off. Turn the scale on. While
Start
is displayed, press and hold the
REWEIGH
key until both the middle arrows
appear on the display.
The test mode has four parameters. They are:
•
Weighing
•
Internal count
•
Battery indication
•
Calibration factor
Alternating between the parameters is performed by pressing the
REWEIGH
key.
Press the
Kg-Lb
key to zero the scale in test mode.
Press the
Kg-Lb
+
REWEIGH
to exit weighing mode.

The battery is low
Recharge the battery.
The display shows
Err message as
detailed in the table
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.
