Reviewing Statistical Information 
 
Once rundown torque values have been stored to memory, it is possible to view statistical values based on those 
rundowns. 
 
To view statistical information: 
 
1.  From either MEMORY MODE or RUN MODE press the AUDIT button. 
A screen will display showing the following statistical values: 
  
n = number of rundowns stored into memory 
 = the mean torque value of all stored rundowns 
  Min = the lowest stored torque value  
  Max = the highest stored torque value 
  s = standard deviation of the stored torque values 
 
2.  If the ATDA is in MEMORY MODE when the statistical values are viewed, pressing the SELECTION 
ARROW buttons will allow the user to scroll through individual rundown values. 
3.  If the ATDA is in RUN MODE when the statistical values are viewed, pressing the SELECTION 
ARROW buttons will return the user to the main display screen 
 
 
Once MEMORY MODE has been enabled and torque values have been stored, all rundowns, regardless of 
whether they are conducted in MEMORY MODE or RUN MODE, will be stored  
 
To disable MEMORY MODE, the user must clear the memory and enter RUN MODE.  For instructions on how 
to clear memory, see Clear Memory (3-3) on page 16.

entered into memory after the set number of seconds, the display will zero and the ATDA will be ready to record 
another torque value.  When in MEMORY MODE, if AUTO CLEAR is turned OFF, the user must manually enter the 
value into memory or clear the value. 
 
1. Set the AUTO CLEAR function to OFF 
2.  While in the Main Display, conduct a rundown 
3.  After observing the rundown, the user must decide whether to save or clear the value. 
4.  If the rundown is determined to be valid, press the ENTER button to store the value.  The Main Display will 
convert back to zero, the next Stored Rundown Number will be displayed and the system will be ready to 
record another torque value. 
5.  If the rundown is determined to be invalid (statistical outlier, operator error during rundown, tool error during 
rundown, etc.), press CLEAR to delete the value.  The Main Display will convert back to zero, the Stored 
Rundown Number will remain the same and the system will be ready to record another torque value.

1. Use the Selection Arrow buttons to scroll to the desired torque reading 
2. Press CLEAR twice
 to clear the value from memory and to subtract it from any statistical calculations.  This 
will leave a gap in the sequential memory addresses but not affect the number of samples used for statistical 
calculations.  
 
Filter (1-2) 
 
The FILTER FREQUENCY is a setting used to “screen out” unwanted signals produced by hand and power tools and 
which can adversely affect the torque values generated by a transducer when connected to the ATDA.  The FILTER 
FREQUENCY of the ATDA can be programmed in order to best match the type of tool being used and to provide the 
most reliable readings.  The values are shown in values from 125 – 2000 Hertz (Hz).  A general starting point for 
programming is 500 Hz for manual and continuous drive tools and 1000 Hz for discontinuous drive tools, but more 
consistent values may be obtained with other settings, depending on tool design, joint characteristics and other 
factors. 
Setting the Filter Value  
 
1.  From the main display press MENU

increase the PEAK BLANKING value.  Either button, when continuously pressed, will advance the value in a 
loop. 
5.  When the desired value is selected, press ENTER to save and exit. 
 
Sign Lock (1-4) 
 
The SIGN LOCK feature allows the user to select the rotation direction in which a torque peak will be captured.  With 
SIGN LOCK on, the initial direction is set as the default direction; a negative torque value indicates a reading taken in 
the counter-clockwise direction and a positive reading indicates a reading taken in the clockwise direction.  Any 
readings taken in the non-selected direction will be measured, but not captured / displayed as a peak value. 
With SIGN LOCK turned off, peak values in both the clockwise and counter-clockwise directions will be captured and 
displayed. 
  
Since most torque rundowns are conducted and readings are taken in the clockwise direction, the user may find it 
beneficial to turn this feature on.

Using the ATDA-DC in AUDIT MODE 
 
Prior to using AUDIT Mode ensure that the correct files have been downloaded from the PC to the 
ATDA-DC tester from the Tool Manager Software 
 
AUDIT MODE is entered by pressing AUDIT button.  The tester will prompt for a USER NAME which can be entered 
from the display using the blue scroll keys to drive the cursor to letters/numerals, once highlighted by the cursor user 
presses the ENT button to select.  When finished entering USER NAME press the blue oval button under DONE text.  
The tester will advance to a list of tools for testing, use blue arrow scroll keys to select tool and press ENT to launch 
test.   
 
Creating, Downloading, Uploading and Archiving Tools/Files 
Jobs Manager or Tool Manager 
 
Jobs Manager/Audit Manager is designed to facilitate residual auditing with either digital wrenches or transducerized 
wrenches. 
 
Tool Manager is designed to test, verify and archive tools. 
 
Both applications create databases on the PC for data to be archived, recalled and analyzed.  The applications 
communicate with other applications via .csv exports 
 
Procedure to Launch 
1. User will launch the application on their computer. 
2. User connects instrument with supplied communication cable 
3.  The communications are serial communication so user must assign a Port.  The application will suggest open ports, user 
selects a port. 
4. User must select Link to PC from main menu 
5. Instrument will generate a message - Waiting… 
User will send Tools or Route/files to tester or wrench. Tool Manager or Jobs Manager will inform user if transfer was 
successful and instrument will have a dialog bar illustrating status of download. 
6. User presses the CLR key to return to Menu. 
7. User presses the AUDIT key to start data collection 
 
After initial setup if user continues to use the same cable and same physical port it is unlikely that the computer will 
reassign the port, therefore this setup is a onetime procedure.  However some computers particularly MS operating 
systems often reassign ports without direction from a user, therefore occasionally the user may have to reassign a 
port manually – this is a MS operating system feature with USB ports.  
  
Tool Manager & Jobs Manager are SQL Lite databases that have been built to support the data collection.  The 
applications have been designed to be simple, powerful and flexible.  It is “open” so MIS or engineers familiar with 
database queries can retrieve tools, jobs, routes and data quickly and efficiently.
