1.0 INTRODUCTION

• 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.

• They are supplied with a RS-232 bi-directional 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.

Operators Manual

3.2 LOCATING

• The scales should not be placed in a location that will reduce the accuracy.

• Avoid extremes of temperature. Do not place in direct sunlight or near air conditioning vents.

• Avoid unsuitable tables. The table or floor must be rigid and not vibrate.

• Avoid unstable power sources. Do not use near large users of electricity such as welding equipment or large motors.

• Do not place near vibrating machinery.

• Avoid high humidity that might cause

condensation. Avoid direct contact with water. Do not spray or immerse the scales in water.

• Avoid air movement such as from fans or opening doors. Do not place near open windows or air-conditioning vents.

• Keep the scales clean. Do not stack material on the scales when they are not in use.

3.2 SETTING UP

• 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.

The scale is in Check weighing mode

: The colons “:” are used to separate pounds from ounces

and for the real time clock.

Next to the LCD are a number of LED’s that show when the weight is below, within or over the limits during check weighing.

Weight LED LCD

below the low limit Amber LO Within the limits Green OK Above the high limit Red HI

NOTE: The LED’s can be set by the user to off, bar or spot mode. See “F3 LED” in section 13.1

7.0 BATTERY

• 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.
