3.3 GENERAL SCALE OPERATION
3.3.1 WEIGHING AN ITEM
1. Ensure that the WT annunciator is lit. If it is not lit, press the Clear key.
2. If necessary, press the Zero key to obtain a weight reading of zero.
3. 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”.
4. Read the weight shown on the display.
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 stabi-
lize.
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 stabi-
lize.
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 TC-100-10 scale, you must enter the tare weight value to the nearest 0.001 lb.
1. Using the numeric keys, key-in the known tare weight and press the Tare key. The dis-
play 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 stabi-
lize.
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.
Page 3-3
Page 11
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. Press the SAMPLE / SAVE key. Press the SAMPLE key. The scale displays “10” and
is prompting you to place ten identical items on the platform.
NOTE: If you wish to change the sample number, simply press the SAMPLE / SAVE key repeatedly until the desired sample number appears. Available choices are 5, 10, 25, 50 and 100.
3 . Place the sample items on the platform all at once.
4. Press the PRINT 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 flashes the UNIT WT/MODE annunciator 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.
3.3.6 CLEARING THE PIECE COUNT
1. To clear the piece count, either press the CLEAR 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 (APW) 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 AVERAGE PIECE WEIGHT (APW) ENTRY
1 . Using the numeric and decimal point keys, key-in the actual unit weight value.
2. Press the APW WT / MODE key. If the unit weight 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 1: 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.
4.2 ALTERNATIVE SAMPLING METHOD
If you wish to use a non-standard sampling size, then use the following procedure.
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 on the scale’s platter.
4. Press the SAMPLE / SAVE 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 flashes the APW WT / MODE annunciator 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.
4.3 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 4.2.
4.3.1 DISPLAYING THE MEMORY ACCUMULATOR
1. Press the MR key. The scale briefly displays the total number of pieces.
4.3.2 ADDING TO THE MEMORY ACCUMULATOR
1. Press the M+ key. The scale adds the current number of pieces to the memory
accumulator.
4.3.3 CLEARING THE MEMORY ACCUMULATOR
1. Press the MC key.
Page 4-1
Page 13
4.4 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 its displayed reading.
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 4.2.
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.

CHAPTER 6: CALIBRATION
6.1 CALIBRATION OVERVIEW
Your TC-100 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 SAMPLE / SAVE key. The scale shows briefly shows “C 0”, then displays a value which remains on the screen. This value is for troubleshooting purposes only. Allow a 20­minute 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 SAMPLE / SAVE key to save the zero point value. The scale shows "0.000" or "0.0000" depending on scale capacity.
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, 2 lb, you need to type “2” followed by zeroes until the “2” is to the left of the decimal point.
7. Place the test weight(s) onto the scale’s platter, then press the SAMPLE / SAVE key. If the calibration was successful, the display will show "END C1" momentarily, then automatically enter 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.

“P” - This command is sent to the scale to print the indicated display. The scale will
not respond if the scale is in motion, positive overload or negative overload.
“Z” - This command is sent to the scale to zero the scale. If the scale is in motion,
the scale will wait until a state of equilibrium is achieved. The scale will not respond at all if the scale is in positive overload or negative overload.
“T” - This command is sent to the scale to tare the scale. If the scale is in motion,
the scale will wait until a state of equilibrium is achieved. The scale will not respond at all if the scale is in positive overload or negative overload. The scale will also not respond if it displaying a negative gross value.
