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.

pressed, will advance the value in a loop. 
5.  When the desired value is selected, press ENTER to save and exit. 
 
 
Clearing a Torque Value / RUN MODE 
 
When in RUN MODE, if Auto Clear is turned on by selecting a time value, the display screen will automatically 
convert back to a zero value after the set amount of seconds. 
 
When in RUN MODE, if Auto Clear is turned OFF, the operator must manually clear a torque value from the display: 
 
 
1. Set the Auto Clear function to OFF 
2.  While in the Main Display screen, conduct a rundown 
3.  After observing the torque value for the rundown, press CLEAR 
4.  The Main Display will convert back to a zero value 
 
 
Clearing / Entering the Current Torque Value / MEMORY MODE 
 
When in MEMORY MODE, if AUTO CLEAR is turned ON, the torque value from a rundown will automatically be 
entered into memory after the set number of seconds, the display will convert back to a zero value 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. 
 
 
 
Clearing a Previous Torque Value / MEMORY MODE 
 
To clear a torque value that was previously entered into memory: 
 
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.  
						

							 
14
Setting the Filter Value  
 
1.  From the main display press MENU 
2. Press the Right Selection button to select PEAK OPTIONS MENU 
3. Use the SELECTION ARROW buttons to select FILTER 
4. Use the Left Selection button to decrease the FILTER value.  Use the Right Selection button to increase 
the Filter 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. 
 
 
Peak Blanking (1-3) 
 
PEAK BLANKING determines the minimum threshold at which a torque peak is captured.  It is entered as a 
percentage of the full scale value of the transducer which is connected to the ATDA and can be displayed in values 
from 2 – 50% of transducer full scale.  Accurately setting the PEAK BLANKING value can help prevent invalid torque 
readings and can enable the user to avoid taking readings related to high prevailing torque in an application. 
 
Setting the Peak Blanking Value 
 
1.  From the main display press MENU 
2. Press the Right Selection button to select PEAK OPTIONS MENU 
3. Use the SELECTION ARROW buttons to select PEAK BLANKING 
4. Use the Left Selection button to decrease the PEAK BLANKING value.  Use the Right Selection button to 
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.
