1.0 INTRODUCTION
•The WBW range provides accurate, fast and versatile general purpose
weighing scales with check-weighing functions.
•There are two series within the range. The WBWa series of scales are
similar to the WBW series of scales except the default units are pounds,
whereas in the WBW series the imperial units are disabled which can be
enabled by the user.
•There are 4 models in each series with capacities up to 16 kg / 35 lb.
•All have stainless steel weighing platforms on an ABS plastic base assembly
which is sealed to IP 65.
•All scales have sealed keypads with colour coded membrane switches and
the displays are large easy to read liquid crystal type displays (LCD). The
LCD’s are supplied with a backlight.
•The scales include automatic zero tracking, audible alarm for pre-set weights
and semi-automatic tare.

4.0 ERROR CODES
ERROR
CODE
DESCRIPTION POSSIBLE CAUSES
Err 4
Initial Zero is greater than
allowed (4% of maximum
capacity) when power is turned
on or when the [Zero/Enter]
key is pressed.
Weight on the pan when turning the
scale on.
Excessive weight on the pan when
zeroing the scale.
Platform is not installed.
Improper calibration of the scale.
Damaged load cell.
Damaged Electronics.
Err 6
A/D count is not correct when
turning the scale on.
Load cell is damaged.
Electronics is damaged.
Err 8
High limit input error Low limit is set first, then the high limit is
set lower than the low limit and high
limit not equal to zero.
Err 9
Low limit input error High limit is set first, then the low limit is
set higher than the high limit and low
limit not equal to zero.
FAIL H or
FAIL L
Calibration error Improper calibration (should be within
+10% of the factory calibration). The old
calibration data will be retained until the
calibration process is complete.
