3.3 Basic Counting
Read this procedure entirely before counting pieces. Piece sampling and counting can be further enhanced using menu
selections in the Count menu. There are several methods that are available for sampling.
 Positive Sampling - given number of pieces are placed on the scale, the weight is divided by the number of pieces
to calculate the Average Piece Weight (APW). Additional pieces are then placed on the scale and counted and dis-
played.
 Negative Sampling - calculates the APW when a given number of pieces are removed from the total quantity.
 The APW can also be entered through the numeric keypad. As parts are placed on the scale, the count is
immediately displayed.
 The Trooper Count will support positive counting or negative counting.
3.3.1 ositive Sampling
If a weighing container is to be used:
 If the tare value is known, enter a Pre-Set Tare.
 If the tare value is not known, place the container
on the pan and press the TARE button.
Press the SAM LE Menu button.

2. If Ref. Wt. is less than minimum, [Err4] [LOW]
[REF] is displayed. See section 6.2.
3.3.2 Negative Sampling
Negative sampling permits the determination of the total quantity on the pan by removing a known number of sample
pieces. The total quantity may be placed directly on the Scale or in a container. The Trooper Count Scale automatically
calculates the remaining pieces after the sample amount is removed. When a container is used, you may enter a
preset tare weight or simply tare the empty container before starting.

3.4 Library Mode
The Trooper Count scale allows the storage of part/counting data in 60 locations, designated ID 00 to ID 59. Each
location includes: part number, Average Piece Weight (APW), a pre-set tare value, over and under count values and an
accumulated piece count.
Data in the library is saved in a manner similar to a computer file. Temporary editing of the data will not affect the saved
data. When desired, the temporary edits can be saved, allowing the scale to be turned off without losing the changes.
Data in ID 00 may not be saved permanently but the data can be easily copied to another location.
The Library, ID 01 to ID 59, can be locked (see 4.9 Lockout Menu) to prevent unauthorized changes to the data. The
accumulated count will not be locked allowing it to be updated. When turned on, the scale defaults to ID 00.
3.4.2 Entering Data Directly into Library
The following example is used to illustrate how to enter data in a particular library location.
Short press on the LIBRARY Save button.
Short presses on the M+ or M- buttons will display
library locations which are already used.
Using the numeric keys, enter the desired library num-
ber. The sample shown is an empty location, ID 22.
Press the Enter button to accept ID 22.

3.4.4 Saving Library Data in Another Location (Cont.)
Automatic reference optimization results in a more accurate count by increasing the reference weight without the need
to count additional parts. A higher reference weight is important when there is a risk of inconsistent piece weights or if
the reference weight is close to the minimum (See section 7.1).
Auto Optimization uses an initial APW to count additional pieces that are placed on the scale. After a few seconds, the
message A-OPt appears in the Data display as the new higher reference weight is used to re-calculate the APW. The
process can be repeated as long as the additional weight is less than the previous reference weight. Once this limit is
exceeded Auto-Opt is turned off. This function can be activated or deactivated in the Count menu. The factory default
setting is on.
3.6 Auto Add Mode
Auto Add Mode is setup for a more accurate count procedure by increasing the minimum reference weight and the
minimum APW limits (see section 7.1). The scale requests additional pieces if the reference weight is less than the
recommended Auto-Add minimum weight in Table 7-2. The instructions to add these additional pieces may be ig-
nored. This function can be activated or deactivated in the Count menu. The factory default setting is off.
Place the stipulated number of pieces on the scale
(e.g. 2 pieces). The scale then determines the new
APW based on the total pieces

3.4.5 Using the Library
To enter the Library, momentarily press the LIBRARY Save button. Use the keypad or the M+ button to enter a location
ID that you wish to use. Press the LIBRARY Save button again to select the new ID. ID XX IN USE will display indicating
that the data stored in that memory is now active. If an APW and a Preset Tare was set, placing a sample filled
container on the scale will give an immediate count.
If the Library is not locked, it is possible to edit the data in the current ID. The changes need not be saved if they were
for temporary use. If the Library is locked, you must change to ID 00 for simple counting use.
At this point, all data from Library 22 has been copied
into Library location 52.

3.7 RS232 Communication
All communication is accomplished using standard ASCII format. Characters shown in the following table are acknowl-
edged by the Scale. Invalid command response "ES" error indicates the Scale has not recognized the command.
Commands sent to the Scale must be terminated with a carriage return (CR) or carriage return-line feed (CRLF). Data
output by the Scale is always terminated with a carriage return-line feed (CRLF). See section 4.7 for RS232 and Print
Setup.
Command Description
Character (LFT is OFF)
Same as pressing PRINT button. Sends print data to peripheral device.
VOutput software version. For example: "TC30 Sr. 1.20"
TSame as pressing TARE. If the Scale accepts the command, it will respond "OK".
If the Scale is in motion, it will output "CANT TARE" until the Scale is stable. When stable, tare is
accepted. (NOTE: If LFT is ON, special tare rules apply.)
ZSame as pressing ZERO button. If the Scale accepts the command, it will respond "OK".
NOTE: Any other command will produce the answer "ES".
