1. INTRODUCTION

The TB series of electronics balances provides an accurate, fast and versatile

series of general purpose balances with counting and % weighing functions.

All models have stainless steel weighing platforms on an ABS base assembly.

All the keypads are light touch switches and the displays are large easy to read

liquid crystal typebacklit displays (LCD). All units have a parts counting function.

All units include automatic zero tracking, automatic tare and an accumulation

facility that allows the count to be stored and recalled as an accumulated total.

2. INSTALLATION

3.1 GENERAL INSTALLATION

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

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

vents.

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

place near vibrating machinery.

Avoid unstable power sources. Do not use near large users of electricity such as

welding equipment or large motors.

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.

Keep the scales clean.

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

3.2 INSTALLATION of TB SERIES

Level the scale by adjusting the four feet. The scale should be adjusted so that the

bubble in the spirit level is in the center of the level and the scale is supported by all

four feet. If the scale rocks, readjust the feet.

Attach the adapter to the connector on the side of the scale.Please make sure the

power supply voltage matches the label on the adapter.

3. KEY DESCRIPTIONS

Zero or Enter

Set the zero point for all subsequent weighing. The display shows zero. A

secondary function, as "Enter" key when setting parameters or other functions.

Tare

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.

Enters the percent weighing function.

When in percentage mode andcurrent value is zero, press this key to return to the

normal weighing mode.

Print or Accumulation

To print the results to a PC or printer using the optional RS-232 interface. It also

adds the value to the accumulation memory if the accumulation function is not

automatic. The secondary function (ESC), is to return to normal operation when

the scale is in a parameter setting mode.

MODE

This key will select either kilograms, pounds or ounces for the weighing unit when

in the weighing mode.

A secondary function is to change the current value for parameters or other

functions.

When in thecounting mode, it allows the weight, unit weight and count to be seen

when parts counting.

Smpl

Use this key to enterthe counting mode when in the normal weighing mode. Also

use this key to return to the normal weighing mode when in the counting mode.

ON/OFF

Use this key to turn the power on or off.

4. OPERATION

4.1 ZEROING THE DISPLAY

You can press the ZERO/ENTER key at any time to set the zero point from which

all other weighing and counting is measured, within 10% of power up zero. This will

usually only be necessary when the platform is empty. When the zero point is

obtained the display will show the indicator for zero.

The scale has an automatic rezeroing function to account for minor drifting or

accumulation of material on the platform. When the weight goes over 20% of the

full capacity, the “read zero” function is obsolete.

4.2 TARING

Zero the scale by pressing the ZERO/ENTER key if necessary. The zero indicator will

be on.

Place a container on the platform. A value for its weight will be displayed.

Press the TARE key to tare the scale. The weight that was displayed is stored as

the tare value and that value is subtracted from the display, leaving zero on the

display. The "TARE" indicator will be on. As product is added only the weight of the

product will be shown. The scale can be tared a second time if another type of

product is to be added to the first one. Again, only the weight that is added after

taring will be displayed.

When the container is removed a negative value will be shown. If the scale was

tared just before removing the container this value is the gross weight of the

container plus all product that was removed. The zero indicator will also be on

because the platform is back to the same condition it was when the ZERO/ENTER

key was last pressed.

4.3 WEIGHING A SAMPLE

To determine the weight of a sample first tare the empty container then place the

sample in the container. The display will show the weight and the units of weight

currently in use.

4.4 PERCENT WEIGHING

The scale will allow a sample weight to be shown as 100%. Then any other weight

placed on the scale will be displayed as a percentage of the original sample. For

example if 350g is placed on the scale and the %key is pressed the display will

show 100.00%.

If you remove the 350g weight and puta 300g weight on the scale the display will

show 85.71%, as 300g is 85.71% of 350g.

Note: the scale may jump by large numbers unexpectedly if small weights are used to

set the 100% level. For example if only 23.5g is on a scale with 0.5g increments

and the scale is set to 100%, the display will show 100.00%, however a small

change of weight will cause the display to jump to 102.13% as one scale division

(0.5g)

Pressing the %key will return the scale to weighing.

4.5 PARTS COUNTING

When the scale isin the weight mode, pressing the SMPL key will start the

parts counting function.

Before beginning, tare the weight of any container that will be used, leaving the

empty container on the scale. Place the number of samples on the scale. The

number should match the options for parts counting, 10, 20, 50, 100 or 200

pieces.

Press the SMPL key to begin. The scale will show "SP 10" asking for a sample

size of 10 parts. The display will cycle through the options: 10, 20, 50, 100, 200

and back to 10.

Press theSMPL key again when the number matches the number of parts used

for the sample. As more weight is added the display will show the number of

parts (pcs).

Press the MODE key to display unit weight (g/pcs), Total weight (kg) or the

count (pcs). Press the SMPL key to return to normal weighing.

4.6 ACCUMULATION

When the scale is set to manual accumulation the weight displayed will be

stored in memory when the PRINT key is pressed and the weight is stable.

The display will show "ACC 1" and then the total in memory for 2 seconds

before returning to normal. If the optional RS-232 interface is installed the

weight will be output to a printer or PC.

Remove the weight, allowing the scale to return to zero and put a second

weight on. Press PRINT, the display will show "ACC 2" and then show the new

total. Continue until all weights have been added.

To view the totals in memory press the PRINT key when the scale is at zero.

The display will show the total number of items "ACC xx" and the total weight

before returning to zero. The totals will also be printed via the RS-232

interface.

To erase the memory pressPRINT to view the totals and then press theSMPL

key to clear the memory.

5. BATTERY OPERATION

When the battery needs charging the indicator will turn on. Please charge the

battery or usethe AC adapter after this indicator turns on.

The scales can be operated from the battery if desired. The battery life is

approximately 50 hours.

To charge the battery simply plug into the mains power. The scale does not need to

be turned on.

The battery should be charged for 12 hours for full capacity.

There is an 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 has a full charge. If it is Red the battery needs charging and

yellow indicates the battery is being charged.

As the battery is used it may fail to hold a full charge. If the battery life becomes

unacceptable then contact your distributor.
