Once brought to the work area, it is important for accuracy and safety reasons to securely mount your Auditor Torque Cube to the workstation prior to use\b The Auditor Torque CubeTM is setup with thruholes for (3/8 / 9mm) x (4 / 1\f\fmm) fastening bolts or screws . During operational use\b the Auditor Torque CubeTM is subjected to rotational forces that require 2 points of attachment to the work station to secure against. Dowel pins of at least 2 / 5\fmm may also be used at the work station which will then allow the unit to be dropped onto and lifted off of the pins for maximum portability. Included with the product\b is a vertical and horizontal mounting template for ease of use.
4INTROD UCTION \b es cr i pti on Thank you for purchasing an Auditor Torque CubeTMtester from AIMCO.

AIMCO’s Auditor Torque Cube TMalso is enabled with RS232 output for use with a serial printer or Windows®PC device. s Y ste m s p ec iFi cati o ns Dimensions\f 3.125 / 79.375 mm Wide 3.75 / 95.25 mm High 3.23 / 82.55 mm Deep 2.5 lb / 1.13 kg Power Requirements\f 926V DC\b 15\f mA min Supplied by 1\f\f22\fVAC Input Transformer Battery\f Internal (nonfield serviceable) NiMh pack Operating Temperature Range\f 32 oF / \foC to 122oF / 5\foC Data Communications\f RS232 Accuracy\f 1% of Indicated Reading within top 9\f% of Full Scale Range\f 1\f% to 1\f\f% of Full Scale Display\f 4 Active Digits Units of Measure\f Eight (8) Selectable Engineering Units: In.Oz.\b In.Lb.\b Ft.Lb.\b Nm\b CNm\b KgfCm\b gfCm\b Kgfm Frequency Filter\f Selectable filtering frequencies: 125Hz\b 25\fHz\b 5\f\fHz\b 75\fHz\b 15\f\fHz
5PREPARING THE ATC FOR USE The ATC testers feature a supplied Joint Simulator(Fig. A) that is configurable to a wide variety of joint conditions. The Joint Simulatoris made up of a series of Bellville Wash ers that allow the user to preconfigure the joint to match the actual application joint as closely as possible. Each of the Bellville Washersis concave in shape. By aligning all 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\b remove the Joint Simulatorfrom its bag. Loosen the Hex Screwand stack the Bellville 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 ATC Tester. Fig\b BFig\b CFig\b D Fig\b A
6BASIC OPERATION Power ON and OFF Pressing any key (CLR\b MDE\b ENG\b ENT) turns unit power ON. Pressing CLR & ENT simultaneously turns unit power OFF. CLR Pressing CLR clears the current reading or zeros the transducer if no reading is current. MDE Pressing MDE will display the current mode for a 1 second period of time. The unit will revert to ACTIVE DISPLAY mode after that time. Depressing the MDE key a second time will scroll through the list of MODES available (“PK\b AC”\b “1PK\bAC”\b ”CAL”\b “TRACK”). Depressing any other key will return the unit to ACTIVE DISPLAY mode. See page 9 for more descriptions. ENG Pressing ENG will display the current Unit of measure for a 1 second period. Pressing ENG while the Units of Measure are displayed will scroll through the available units (Kgf M\b Kgf Cm\b gf Cm\b Ncm\b Nm\b FT LB\b IN LB\b IN OZ). Pressing any other key will return to SAMPLE mode. ENT Pressing ENT will send the current reading to the serial port and clears the screen. MDE & ENG Pressing MDE & ENG buttons simultaneously displays the Program Menu. See Program Menu section for details. ACTIVE DISPLAY Active Display Mode is the normal operating mode used by the Auditor Torque Cube TMfor measurement. When a measurement is taken\b the transducer reading or peak is dis played for the length of time set by Auto Clear (see Program Menu). If High and Low lim its have been preset (see Program Menu) then the LED light will show Green for a sample within the limits\b or Red for one that is outside the preset limits. In Peak and 1 st Peak modes\b the LED will illuminate Green upon completion of the reading if no limits are preset in the unit. No LED illumination will occur during Track mode.
7PROGRAM ME NU Buttons for Menu Navigation ENG Functions as an UP button in this menu. Pressing ENG sequentially advances the menu to the next item. MDE Functions as a DOWN button in this menu. Pressing MDE sequentially advances the menu to the previous item. CLR Pressing CLR will exit from the PROGRAM MENU and return the unit to ACTIVE DISPLAY MODE. ENT Pressing ENT will change the current item as advanced to or displayed in the PROGRAM MENU AC Auto Clear is time\b in seconds 19 and off. When AC is displayed\b pressing ENT will sequentially advance the time increment by 1 second at each press of ENT. After 5 seconds of no changes\b the unit will revert to Active Display Mode and the last shown setting will be held. Setting OFF will deactivate the Auto Clear function and readings will need to be cleared from the screen manually using the CLR key. FILT Peak filter frequency response in Hz. Options of 125\b 25\f\b 5\f\f\b 75\f and 15\f\f are avail able. Press ENT key to sequentially scroll thru these options. After 5 seconds of no changes\b the unit will revert to Active Display Mode and the last shown setting will be held. PPER (PEAK BLANKING\A) Minimum peak as a percentage of full scale. Readings below the SET value will not be displayed. Settings in the range of 2%5\f% are available. Pressing ENT will sequentially increase the % by one with each press. At 5\f% the unit will scroll back to 2% with the next press of ENT. After 5 seconds of no changes\b the unit will revert to Active Display Mode and the last shown setting will be held. SL Sign Lock. Options of ON or OFF are available. Press ENT to scroll between the selections. After 5 seconds of no changes\b the unit will revert to Sample Mode and the last shown setting will be held. LOW Lower limit target. A setting of \f.\f\f\f disables the limit. Press ENT to enter the Number Edit Mode. The current digit or decimal point flashes. The Number Edit Mode will remain active with out time out until the CLR button is pressed.

9CHARGING THE BATTERY The internal battery pack contained in the Auditor Torque CubeTM is nonuser serviceable. When treated properly \b the battery pack should provide approximately 12 hours of con tinuous use from a full charge. The battery chemistry contained within the Auditor Torque CubeTM is NiMh and charges with the supplied power transformer . Any time the Auditor Torque CubeTM is plugged in\b the batteries are trickle charged at a rate that takes approximately 8 hours for a full charge . There is no indication to the user that the unit is charging and it is recommended to simply leave the unit charging at anytime it is not in use . There is no harm in leaving the charger connected and this will actually improve battery life. If the Auditor T orque CubeTM is going to be stored for a lengthy period of time \b it is rec ommend to charge the battery prior to doing so . Also note\b the unit should be checked and charged on a bimonthly basis to insure that the batteries remain in a chargeable condition. SIDE PANEL INPUT / OUTPUT When viewing the Auditor Torque CubeTM from the operators perspective\b there are 2 connectors on the left side of the unit. DC IN The interface for the AC Adapter that was supplied with the unit is the upper connector. This connection may be used when the unit is charging or during operation. Use only the supplied Auditor T orque CubeTM AC Adapter with this unit. Use of any other adapter may cause damage to the unit. RS232 The lower connector is for an RS232 (P/N RS232) cable enabling connection to a se rial printer\b data collector\b computer or other RS232 enabled device. Values are sent via RS232 each time the unit Auto Clears (AC) or the ENT or CLR buttons are pressed.
