SAFETY REQUIREMENTS
SAVE THESE INSTRUCTIONS
1) WORK AREA
a) Keep work area clean and well lit. Cluttered and dark areas invite accidents.
b) Do not operate power tools in explosive atmospheres, such as the presence of flammable
liquids, gases or dust. Power tools create sparks which may ignite the dust or fumes.
c) Keep children and bystanders away while operating a power tool. Distractions can cause you to
lose control.
2) ELECTRICAL SAFETY
a) Power too plugs must match the outlet. Never modify the plug in any way. Do not use any
adapter plugs with earthed (grounded) power tools. Unmodified plugs and matching outlets will
reduce risk of electric shock.
b) Avoid body contact with earthed or grounded surfaces such a s pipes, radiators, ranges and
refrigerators. There is an increased risk of electric shock if your body is earthed or grounded.
c) Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the
risk of electric shock.
d) Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the power tool.
Keep cord away from heat, oil, sharp edges or moving parts. Damaged or entangled cords
increase the risk of electric shock.
e) When operating a power tool outdoors, use an extension cord suitable for outdoor use. Use of a
cord suitable for outdoor use reduces the risk of electric shock.
3) PERSONAL SAFETY
a) Stay alert, watch what you are doing and use common sense when operating a power tool.
Do not use a power tool while you are tired or under the influence of drugs, alcohol or
medication. A moment of inattention while operating power tools may result in serious personal injury.
b) Use safety equipment. Always wear eye protection. Safety equipment such as dust mask, non-skid
safety shoes, hard hat, or hearing protection used for appropriate conditions will reduce personal
injuries.
c) Avoid accidental starting. Ensure the switch is in the off-position before plugging in. Carrying
power tools with your finger on the switch or plugging in power tools that have the switch on invites
accidents.
d) Remove any adjusting key or wrench before turning the power tool on. A wrench or a key left
attached to a rotating part of the power tool may result in personal injury.
e) Do not overreach. Keep proper footing and balance at all times. This enables better control of the
power tool in unexpected situations.
f) Dress properly. Do no wear loose clothing or jewelry. Keep your hair, clothing and gloves away
from moving parts. Loose clothes, jewelry or long hair can be caught in moving parts.
g) If devices are provided for the connection of dust extraction and collection facilities, ensure
these are connected and properly used. Use of these devices can reduce dust-
related hazards.
4) POWER TOOL USE AND CARE
a) Do not force the power tool. Use the correct power tool for your application. The correct power
tool will do the job better and safer at the rate for which it was designed.
b) Do not use the power tool if the switch does not turn it on and off. Any power tool that cannot be
controlled with the switch is dangerous and must be repaired.

Basic Navigation and Use of the Keypad
Many functions of the Auditor AUET Desktop Torque Tester can be accessed by using the button directly below
the associated text on the display screen. For example, if the following screen were displayed:
the LEFT SELECTION BUTTON, which is directly below the MENU text field, would allow the user to access the
MENU features.
At anytime during use, pressing the ENTER button (Figure 1) will allow the user to back up by one screen. Pressing
the ENTER button enough times will always take the user back to the main display screen.
A full diagram of the AUET menu structure is shown in Appendix A.
Turning On / Off
To turn the AUET on, press the “ON” button (Figure 1)
The AIMCO logo will be displayed for approximately 4 seconds followed by the following display:
To turn the AUET off, simply press the “OFF” button.
Preparing the AUET for Use
The AUET testers feature a supplied Joint Simulator (Fig. A) that is configurable to a wide variety of joint conditions.
The Joint Simulator is made up of a series of Beville Washers that allow the user to pre-configure the joint to match
the actual application joint as closely as possible. Each of the Beville Washers is concave in shape. By aligning all

7
the concave curves in the same direction a simulated hard joint is achieved (Fig. B). Alignment of the concave
shapes in an opposing manner a simulated soft joint is achieved (Fig. C). Differing combinations allow for simulated
medium joints to be achieved (Fig. D).
Prior to use, remove the Joint Simulator from its bag. Loosen the Hex Screw and stack the Beville Washers
according to your joint condition needs. Hand thread the Hex Screw into the housing several threads. Place the
square drive end of the simulator into the female square drive on the AUET Tester.
BASIC FUNCTIONS
OPERATING MODE Descriptions
By selecting the proper Operating Mode the user can properly take torque readings from a variety of manual and
powered tools.
 PEAK
This mode will provide a display of the maximum torque value achieved by the tool during operation. This
mode is used for all continuous drive tools and click-type torque wrenches.
 1
st
PEAK
This mode will detect and display the “first peak” achieved by click wrenches and cam-over screwdrivers.

PULSE
This mode will display the maximum torque value achieved by discontinuous drive tools such as pulse tools
and impacting tools.

TRACK
This mode will display torque in real-time as it is applied to the connected transducer. Track mode is used
primarily for calibration of the unit.
Selecting the Proper OPERATING MODE
While in the Main Display screen, press the Selection Arrow-Down button to cycle through the available Operating
Mode choices. The choices will be displayed in the following order:
Selecting the Proper DATA MODE
The AUET contains two Data Modes. RUN and MEMORY.
RUN mode simply allows the tester to display Torque data from the driving source immediately after rundown is

complete. Data will be displayed on the screen until manually cleared or until preset Auto Clear time has elapsed.
No values are stored while in RUN mode.
MEMORY mode displays the Torque data from the run and stores it sequentially in the internal memory of the tester.
The memory location is displayed in the upper left corner of the tester screen. When entering MEMORY mode, the
UP arrow key must be pressed to reach the first open memory location (ie. 001). If values have already been stored
in the tester memory, the up arrow will need to be pressed until the next open memory location is reached (if 12
values are stored, then the UP arrow would need to be pressed until the memory location display reads 013). If it is
desired to return to the RUN mode (no storage), the DOWN arrow should be pressed repeatedly until the memory
location indicator goes to 000 and disappears. Pressing the MEM menu key will then return the unit to RUN mode
Setting ENGINEERING UNITS
The AUET must be in RUN MODE in order to change the Engineering Units. If torque values have been stored in
the AUET while in MEMORY MODE, then the memory must be cleared in order to change the Engineering Units.
While in the Main Display screen, press the Selection Arrow-Up button to cycle through the available Engineering
Unit choices. The choices will be displayed in the following order:
Using the AUET in RUN MODE
RUN MODE can be used to quickly and easily take torque readings using a variety of tools in situations where
storage of data and statistical feedback is not necessary.
Using the AUET in RUN MODE
With the AUET turned ON, observe the Data Storage Mode Status field (Figure 1). If RUN is displayed, the AUET is
in RUN MODE and can then be configured accordingly. If the status reads MEM, then the AUET is in MEMORY
MODE.
Install the supplied driving bit into the Torque applying device to be tested. Engage the driving bit into the Hex screw
in the supplied joint simulator and run the torque applying device per its instructions. The Main Display Screen will
show the Torque value received by the built in transducer.
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
Using the AUET in MEMORY MODE
Prior to using Memory Mode for the first time, it is advised to perform a Reset All to insure that
any data is erased and that all Memory locations are formatted (see Reset All, pg…)
MEM MODE can be used to store up to 999 torque readings. Those stored readings can then be reviewed and
statistical analysis can be conducted. The AUET also provides the capability to print out the data with or without the

9
associated statistical information.
With the AUET turned ON, observe the Data Storage Mode Status field (Figure 1). If MEM is displayed, the AUET is
in MEMORY MODE and can then be configured accordingly. If the status reads RUN, then the AUET is in RUN
MODE and will not store any of the following rundown values.
To switch the unit to MEMORY MODE from RUN MODE, press the RIGHT SELECTION BUTON (Figure 1) and
verify that MEM is displayed in the DATA STORAGE MODE field.
Storing Rundown Torque Values
1. Enter MEMORY MODE
2. Press the SELECTION ARROW – UP button to scroll to memory position 1, which will be indicated by a
001 in the Stored Rundown Number field (Figure 1). The subsequent rundown value will be stored as
#001 and all other rundowns will automatically be stored as sequentially higher numbers.
In MEMORY MODE, torque values are automatically stored when the value is cleared; this time-value is determined
by the time-value set in the Auto-Clear function. If the Auto Clear function is turned off, the user must press ENTER
after each rundown in order to store the associated torque 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 AUET 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.
Once a rundown torque value is displayed, the value must be entered or cleared before a subsequent value
can be displayed.
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. The
Stored Rundown Number of all values entered after the cleared value will automatically be reduced by one.
To switch the unit to RUN MODE from MEMORY MODE, press the RIGHT SELECTION BUTON (Figure 1) and
verify that RUN is displayed in the DATA STORAGE MODE field.
Reviewing Rundown Torque Values
To review rundown values that have been stored in MEMORY MODE:
1. Enter MEMORY MODE
2. Using the SELECTION ARROW buttons, scroll UP or DOWN through the list of stored rundown values.
It is possible to scroll to a stored-rundown-number which is above the highest stored value; for example, if
10 rundowns have been stored, it is possible to scroll to stored-rundown-number 15, however all rundown

10
values above 10 will display as zero values.
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 MENU button.
2. Press the UP menu scroll button until the Data Menu (3 of 3) item is displayed
3. Press SEL to enter into the Data Menu area
4. Press the UP menu scroll button until Display SPC Info 3 of 5) item is shown
5. Press SEL to select and display Statistical Information for the set of data stored in the AUET
A screen will display showing the following statistical values:
n = number of rundowns stored into memory
X = mean torque value of all stored rundowns
Min = the lowest stored torque value
Max = the highest stored torque value
To disable MEMORY MODE, the user must clear the memory and enter RUN MODE. For instructions on how
to clear memory, see Clear Memory (3-4, 3-5) on page XX
