1.0 INTRODUCTION

• The CBC series provides accurate, fast and versatile counting

scales.

• There are 2 type of scales within the CBC series-

CBC scales are gram/ kilogram only scales and the CBCa scales

are changeable from pounds to kilograms. The scales have the same functions except that CBCa scales have the ability to toggle between the two weighing units.

• There are 5 models in each type with capacities up to 48 kg / 100lb.

• The scales have stainless steel weighing platforms on an ABS base assembly.

• All scales are supplied with a RS-232 bi-directional interface and real time clock (RTC).

• The scales have sealed keypad with colour coded membrane switches and there are 3 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 preset counts, automatic tare, pre-set tare, an accumulation facility that allows the count to be stored and recalled as an accumulated total.

3.0 INSTALLATION

3.1 LOCATING THE SCALE

• 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 airconditioning vents.

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

3.2 INSTALLATION OF CBC SCALES

• The CBC Series come 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.

• Turn the power ON using the switch located on the right side of the base.

• The scale will show the current software revision number in the “Weight” display window, for example V3.06.

• Next a self-test is performed. At the end of the self-test, it will display “0” in all three displays, if the zero condition has been achieved.

Numeric entry keys, used to manually enter a value for tare weights, unit weight, and sample size.

Used to clear the unit weight or an erroneous entry.

Add the current count to the accumulator. Up to 99 values or full capacity of the weight display can be added. Also prints the displayed values when Auto print is switched off.

To recall the accumulated memory.

To set the upper limit for the number of items counted. When this upper limit is exceeded the scale will sound the beeper.

To print the accumulated totals to a PC or printer using the RS-232 interface.

Used to input the number of items in a sample.

Used to enter the weight of a sample manually. For CBCa it will also select the weighing unit when the “Unit Weight” display is at zero.

Tares the scale. 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. Entering a value using the keypad will store that as the tare value.

Sets the zero point for all subsequent weighing to show zero.
