6 Counting

User Instructions for TB/TC Series Balances

6 Counting

You can use the balance to determine the number of identical

components in a batch by first carrying out a sample weighing

operation.

If the balance is linked to a peripheral such as a tally roll printer

you can obtain a printed record.

Notes

The balance will not sample if the display shows the under weight

lower bars or over weight upper bars.

To count a different component repeat the counting procedure.

1. Either

Ensure that the pan is empty and the display shows zero.

Place an empty container on the pan.

Press T to zero the weight display.

2. Place a number of components on the balance pan.

These components are called the sample size. The sample

size can comprise 5 – 50 components in steps of 5.

3. Press and hold until the display shows the

required sample size.

The display shows SPLE followed by the sample sizes in

steps of 5. This is the number of components you intend to

use in the initial sample. The scrolling sequence always

starts at the last selected sample size. When you release

the key the display shows the sample size and a small c in

the top right hand corner of the display to designate count is

in operation.

7 Checkweigher

User Instructions for TB/TC Series Balances

7 Checkweigher

The checkweigher unit (part number 70571–644) is a simple

device which indicates if the item being weighed is within two

tolerances. The unit can also be used for checkcounting, see

section 7.4.

7.1 Installation

The unit is simple to install. Just plug the unit into the output port

at the back of the balance and switch on.

Note

Early versions of the TC/TB series cannot be connected to the

checkweigher. Before using a checkweigher with an existing TC

or TB balance check the label on the rear face of the balance.

The balance identity code must contain the numbers 35 or 45, for

example TC060–1 35Z.

7.2 Calculating tolerances

The two tolerances are called UNDER and OVER limits. The

UNDER limit is the lowest acceptable number. The OVER limit is

the highest acceptable number. To enter the limits you must place

components on the pan until the required value is reached.

Pressing T enters the value. Pressing g

g clears the

previously entered value. These values are stored in the balance.

Example

To weigh an item to $10% you must first calculate the UNDER

and OVER limits. If an item weighs 100 grams the UNDER value

is 90 grams and the OVER value is 110 grams.

7.3 Checkweighing

1. Switch on the balance with the checkweigher connected.

The balance display shows the last stored UNDER value

and a small u to the right of the display.

2. To accept the UNDER value, press T and go to

step 6.
