• The CBK range of scales provides an accurate, fast and versatile
general purpose weighing scales with parts counting, percent
weighing and check-weighing functions.
• There are two series within the range. The CBKa series are
similar to the CBK series except the CBKa scales can operate in
both imperial and metric weighing units, whereas for the CBK
series the imperial units are not available.
• All models have LEDs to indicate when a weight is below the low
limit, between the limits or above the high limit next to the display.
These can work in conjunction with an audible alarm for check
weighing as well as LCD showing LO, OK and HI.
• All scales have stainless steel weighing platforms on an ABS
base assembly.
• All scales are supplied with a RS-232 bi-directional interface, an
optional USB serial interface and real time clock (RTC).
• The scales have sealed keypads with colour coded membrane
switches and a large easy to read liquid crystal type display (LCD)
supplied with a backlight.
• They include automatic zero tracking, semi-automatic & pre-set
tare, accumulation facility that allows the weight to be stored and
recalled as an accumulated total.

• The CBK Series comes with a stainless steel platform packed
separately.
• Place the platform in the locating holes on the top cover.
• Do not press with excessive force as this could damage the load
cell inside.
• Level the scale by adjusting the four feet. The scale should be
adjusted such that the bubble in the spirit level is in the centre of
the level and the scale is supported by all four feet.
• Attach the power cable to the connector on the base on the left of
the scale. Plug in the power cable to the mains. Switch on the
power switch located on the base on the right side of the scale.
• The scale will first display the software revision then run a selftest. At the end of the self-test it will display zero weight when a
stable condition has been achieved. A stable symbol and zero
symbol indicators are also displayed.
Sets the zero point for all subsequent
weighing. The display shows zero.
It tares the scale and stores the current
weight in memory as a tare value,
subtracts the tare value from the weight
and shows the results. This is the net
weight.
This is used to select the weighing units
from a preset list of available units.
It sets the limits for check weighing and
allows setting of either the low limit or
the high limit or both.
It stores and recalls any of 10 preset
limits
This is used to select percent weighing,
RS-232 parameters, Operation of the
bar graph, RTC settings, User ID and
Scale ID.
Enter Parts Counting
It is used to print the results to a PC or
printer using the RS-232 interface. It
also adds the value to the accumulation
memory if the accumulation function is
not automatic.
Allow entering numerical values where
required, setting of limits, time and date
for example.
Escape from any setting menus
Accept the set values
Allows the weight, unit weight,
and count to be seen when
parts counting or to change from
weight to % in percent weighing
• The scales can be operated from the battery, if desired. The
battery life is approximately 90 hours.
• When the battery needs charging a symbol on the display will turn
on. The battery should be charged when the symbol is on. The
scale will still operate for about 10 hours after which it will
automatically switch off to protect the battery.
• To charge the battery, simply plug into the mains power supply.
The scale does not need to be turned on.
• The battery should be charged for 12 hours for full capacity.
• To the left of the display is a LED to indicate the status of battery
charging. When the scale is plugged into the mains power the
internal battery will be charged. If the LED is green the battery is
being charged. If it is red it is nearly discharged and yellow
indicates the battery is increasing the charge level. Continue to
charge overnight for a complete re-charge.
8.0 BACKLIGHT
The backlight for the LCD can be set by the user to always off, always on or
automatic (on only when the scale is in use or a key is pressed). See setting
of the parameter “S2 bL” in section 13.3.
9.0 AUTO POWER OFF
The auto power off can be set by the user to disable the feature or to a preset time interval. See setting of the parameter “S3 AoF “ in section 13.3.
