3.3 GENERAL SCALE OPERATION

3.3.1 WEIGHING AN ITEM

1. If necessary, press the Zero key to obtain a weight reading of zero.

2. Place the object to be weighed on the scale’s platter and allow the weight
indication to stabilize. If the item weight exceeds the scale’s weight capacity, it
displays “o o o o o”.

9

3. Read the weight shown on the display.

Note: If you wish to change the unit of measure, press the Unit key.

3.3.2 TARING AN ITEM OF UNKNOWN WEIGHT

To weigh an item in a container, the weight of that container must first be subtracted
from the overall weight to obtain an accurate weight reading. This is known as taring.

1. If necessary, press the Zero key to obtain a weight reading of zero.

2. Place the empty container on the scale’s platter and allow the weight indication
to stabilize.

3. Press the Tare key. The TARE light comes on and the scale displays a weight
reading of zero.

4. Place the material to be weighed in the container and allow the weight indication
to stabilize.

5. Read the weight shown on the display.

3.3.3 TARING AN ITEM OF KNOWN WEIGHT

If the weight of the container or object is known, you may enter this weight via the
keyboard. This value must be rounded to the nearest scale division. For example, on
a 60 x 0.005 lb scale, you must enter the tare weight value to the nearest 0.005 lb.

1. Using the numeric keys, key-in the known tare weight and press the Tare key.
The display shows minus weight and turns the TARE annunciator on.

2. Place the material to be weighed in the container and allow the weight indication
to stabilize.

3. Read the weight shown on the display.

3.3.4 CLEARING A TARE

1. To clear a tare, press the ZERO key at any time. The TARE annunciator
disappears and the gross weight is displayed.

3.3.5 PIECE COUNTING

This mode is used to indicate the number of pieces of an item you have placed on
the scale’s platform. To ensure accuracy, the parts you are counting must be
consistent in weight.

The scale uses the sampling method to determine the average piece weight (APW)
of the items you wish to count. When sampling items, always count the parts in your
hand and place them on the platform all at once. If the APW of the items is too light
or the total weight of the sample is too light, accuracy cannot be guaranteed. You will
get an error message, but piece counting will still be allowed. Consult Table 3-2 for
minimum piece weights and sample weights.

1. If the items you will be counting require a container, you must first tare the
container off by pressing the TARE key. The scale switches to TARE mode and sets
the displayed weight to zero.

2 . Place the sample items on the platform all at once.

3. Using the numeric keys, key-in the number of items you have placed o the

10

scale’s platter.

3.3.6 CLEARING THE PIECE COUNT

1. To clear the piece count, either press the CLR key to erase the sample or repeat
the steps in Section 3.3.5.

CHAPTER 4: ADVANCED FEATURES AND OPERATION

4.1 AVERAGE PIECE WEIGHT ENTRY

If you already know the Average Piece Weight or APW of the items you wish to count, then
use the following procedure.

4.1.1 APW ENTRY FROM SCALE

1. Using the numeric and decimal point keys, key-in the actual Average Piece
Weigh value.

2. Press the ENT key. If the APW is large enough, the scale will now display the
number of pieces on the scale. If it does not, the scale briefly displays an error
message, but still allows piece counting. Please see Appendix C for an
explanation of the error messages.

NOTE: If the scale displays an “Error 10” message, the unit weight of the items
you wish to count is too light for your scale to process at all.

4.1.2 APW ENTRY FROM REMOTE SCALE

To use this method, you must have either a TC-100 or a PBS Series scale
connected to the TC-200. See Appendix B for cabling requirements.

NOTE: The TC-100 or PBS Series scale must be configured for “Transmit APW
Mode”. See TC-100 or PBS Series manual for more information.

1 . Perform the sampling on the remote scale.

2. Press the PRINT key on the remote scale. If the APW is large enough, the TC­200 scale will now display the number of pieces on the scale. If it does not, the
TC-200 scale briefly displays an error message, but still allows piece counting.
Please see Appendix C for an explanation of the error messages.

4.2 MEMORY ACCUMULATOR

Your scale comes equipped with a handy memory accumulator, which can be used in
conjunction with the piece counting feature. As with a hand-held calculator, the memory
accumulator can be added to, displayed and cleared at anytime.

NOTE: Make sure the scale is in piece counting mode. If it is not, follow the sampling
procedure found in Section 3.3.5 or the alternative sampling procedure found in Section

4.1.

4.2.1 DISPLAYING THE MEMORY ACCUMULATOR

1. Press the MR key. The scale briefly displays the total number of pieces.

4.2.2 ADDING TO THE MEMORY ACCUMULATOR

1. Press the M+ key. The scale adds the current number of pieces to the
memory accumulator.

4.2.3 CLEARING THE MEMORY ACCUMULATOR

1. Press the MC key.

12

4.3 USING THE TARGET VALUE

This function works in conjunction with the piece counting feature and allows your scale to
act as a checkweigher. This is useful if you are filling a container with a pre-determined
amount of items.

To use, you must enter a target value. For example, if you wish to fill a bottle with 100 items
you would set your target value to 100.

If the number of items on the platform matches or exceeds the target value, the scale
flashes the TGT annunciator and beeps.

1. First, make sure the scale is in piece counting mode. If it is not, follow the sampling
procedure found in Section 3.3.5 or the alternative sampling procedure found in
Section 4.1.

2 . Use the numeric keys to key-in the target value then press the TARGET key.

3. Place items on scale until the scale signals that the items are equal to or greater than
the target value.

NOTE: To exit the target function, press the TARGET key once.

Press the SAMPLE key. If the sample meets the limits shown in Table 3-2, the scale will
now display the number of pieces on the scale. If it does not, the scale lights one of the
error annunciators but still allows piece counting. If this occurs, you should use a higher
sample amount to achieve better piece count accuracy. Please see Table 3-1 for an
explanation of the error annunciators.

NOTE1 : If the scale displays a “Error 10” message, the unit weight of the items
you wish to count is too light for your scale to process at all.

NOTE2 : To further increase the accuracy of this operation, the TC-200 uses a
feature called "Automatic Average Weight Improvement" (AAWI). This feature
automatically updates the current APW when small quantities of pieces – two to
current piece count – are added to the platform. For example, if the current piece
count shown on the display is 10, then adding 2 to 10 more pieces on the
platform at the same time will trigger AAWI. When this occurs, the Unit Wt.
Screen will show dashes briefly then update the new APW value.

1

1

This feature is available only when the A10 setting is enabled (see Chapter 5). The A10 menu may not
appear on some earlier units. If your scale does not have an A10 menu, then AAWI is automatically turned
on for you and is not configurable.

CHAPTER 6: CALIBRATION

6.1 CALIBRATION OVERVIEW

Your TC-200 scale ships from the factory fully calibrated. There is no need to calibrate the
scale unless you feel that it has become inaccurate. It is a good idea to check the
calibration of your scale from time to time with a precision test weight. Transcell
recommends that you perform a new calibration on your digital scale at least once a year.

During calibration, at least two values are saved in the scale’s memory – the zero
value (deadweight) and the up to three span values (test weights). See Table 6-1
for a listing of minimum and recommend test weights.

6.2 CALIBRATION MODE

1. Toggle the ON/OFF switch to the OFF (0) position.

2. Press and hold the ZERO key while powering back on the scale. When the scale
shows
” o Zone” you are in Calibration mode and you may release the ZERO key.

3. Press the ENT key. The scale shows “C 0” on the middle screen and displays a value
on the right hand screen. The “C 0” indicates that the scale is prompting for the zero
calibration value. The value to the right is for troubleshooting purposes only. Allow a
20-minute warm-up period for the load cell and electronic components to become
thermally stable.

4. Remove all items from the scale’s platter. Press ZERO to zero the value.

5. Press the ENT key to save the zero point value. The scale shows "0.000" on the left
screen,
“C 1” on the middle screen and a value on the right screen. The “C 1” indicates that
the scale is prompting for the first span calibration value. The value to the right is for
troubleshooting purposes only.

6. Use the numeric keys to enter the test weight value. Please note that the decimal point
is fixed so that if you are entering, for example, 6 lb, you need to type “6” followed by
zeroes until the “6” is to the left of the decimal point.

7. Place the test weight(s) onto the scale’s platter, then press the ENT key. If the
calibration was successful, the display will show "END C1" momentarily, then prompt
for the next span calibration value.

8. If you wish to use up to two more calibration test weights, repeat Step 7 twice. Each
subsequent test weight must be greater than the last. If you do not wish to use more
calibration test weights, simply press ENT twice. The scale then automatically enters
Normal Operating Mode by performing a countdown test. Remove the test weight from
the platter

NOTE: If you encounter a failure, consult Appendix C for possible causes and
remedies.
