3 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 tool 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 as 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 not wear loose clothing or jewelry. Keep your hair, clothing, and gloves away from moving parts. Loose
4 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. c) Do not exceed transducer torque value or the rated torque value of joint rundown kit. Applying excess torque will damage transducer and joint rundown kit.

7 OPERATING INSTRUCTIONS Selecting the Active Transducer 1. Rotate the Transducer Selection knob (Fig 2.) to select the active transducer. 2. All functions of the AUET/MTM system outlined below will pertain to the active transducer only 3. Active transducer will be shown by an illuminated LED lamp adjacent to the active built-in transducer, or no LED lamp visible when using a transducer connected to the external port. 4. Built-in transducers are preset and ready for use immediately upon selection. External transducers require setup and an additional cable (optional accessory). Intelect transducers do not require setup. (See page 17) Charging the Auditor AUET/MTM Desktop Torque Tester 1. Plug the 100 – 240 VAC Charger into DC Power Supply port (Figure 3) 2. Plug the Charger into a 100–240 VAC power outlet using the appropriate plug end. 3. Press the “Off” button on the front panel (Figure 1) 4. The Charging Mode Indicator LED (Green, next to “ON” button) should begin to flash green. symbol will be displayed on the Main Display screen if the unit is turned on. 5. When the AUET/MTM is fully charged the LED will stop flashing. 6. The AUET/MTM can be used as normal in AC mode with the charger connected. 7. When used in DC mode (Battery) and the battery charge is low, the symbol (low battery) will show on the Main Display screen, see Figure 1, (19). The 100–240VAC Charger should be plugged into the unit immediately to continue uninterrupted operation. Basic Navigation and Use of the Keypad Many functions of the Auditor AUET/MTM 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 any time 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. Pressing the CLR button will return you to the RUN or sequential MEM mode of the AUET/MTM tester. Turning On / Off To turn the AUET/MTM on, press the “ON” button (Figure 1). The AIMCO logo will be displayed for approximately 4 seconds, then the unit will start at the RUN or sequential MEM mode of the tester. To turn the AUET/MTM off, simply press the “OFF” button.
8 Preparing the AUET/MTM for Use The AUET/MTM testers feature a supplied Joint Simulation Kit (Fig. A) that is configurable to a variety of joint conditions. Fig. A The Joint Kit is made up of a series of Belleville Washers that allow the user to pre-configure the joint to match the actual application joint as closely as possible. Each of the Belleville Washers is concave in shape. By aligning all the concave curves in the same direction a simulated hard joint is achieved (Fig. B). Fig. B Alignment of the concave shapes in an opposing manner a simulated soft joint is achieved (Fig. C). Fig. C Differing combinations allow for simulated medium joints to be achieved (Fig. D). Fig. D Joint kits can be adjusted by loosening the Hex Screw and aligning the stack the Belleville 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/MTM 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 impact or impulse tools, dial wrenches and to identify highest torque delivered with click type wrenches. 1st PEAK This mode will detect and display the “first peak” achieved by click wrenches and cam-over screwdrivers. PULSE This mode counts the number of events (pulses or impact blows) in a cycle. This mode does not change the manner in which peak torque is identified. 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 or identifying the condition of the transducer. In Track Mode with no torque on the transducer, the display should show zero.
9 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/MTM 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/MTM must be in RUN MODE in order to change the Engineering Units. If torque values have been stored in the AUET/MTM 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/MTM 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. With the AUET/MTM turned ON, observe the Data Storage Mode Status field (Figure 1). If RUN is displayed, the AUET/MTM is in RUN MODE and can then be configured accordingly. If the status reads MEM, then the AUET/MTM 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 kit and run the torque applying device per its instructions. The Main Display Screen will show the Torque value received by the built in transducer.
10 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. Auto Clear clears the display and sends the value out to the serial port automatically. 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 and the torque value is sent out to the serial port automatically. Using the AUET/MTM 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. 17). 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/MTM also provides the capability to print out the data with or without the associated statistical information. With the AUET/MTM turned ON, observe the Data Storage Mode Status field (Figure 1). If MEM is displayed, the AUET/MTM is in MEMORY MODE and can then be configured accordingly. If the status reads RUN, then the AUET/MTM 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 BUTTON (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/MTM 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
