 RUNDOWN FIXTURE 11 
 
RUNDOWN FIXTURE MAINTENANCE 
The test stands require very little maintenance; however, periodic lubrication of the 
rundown fixture is critical to the longevity of the tool and repeatability of tool testing. The 
rundown bolt and washers should be periodically removed and inspected, and if 
necessary, coated with a high pressure anti-seize lubricant.   
We recommend McMaster Carr part number 1028K65 Standard Nickel Antiseize 
Lubricant.  After lubrication, replace the rundown washers as shown below. (some units 
have an additional washer installed. If there are 6 washers on your unit, install the last one 
to the right of the last washer shown below, facing the same way).  You can configure 
your rundown to be “harder” or more “compliant” this may affect your torque result. 
 
 
 
 
 
 
 
 
 
 
Reaction Points 
 
IT IS THE RESPONSIBILITY OF THE USER TO UNDERSTAND 
PROPER REACTION GEOMETRY.  INJURY TO THE OPERATOR 
AND/OR DAMAGE TO THE TOOL AND/OR TEST STAND WILL 
RESULT IF PROPER REACTION IS NOT PROVIDED.

DESCRIPTION OF FUNCTIONS 
The following is a description of the standard features of the Auditor product line. 
 
OPERATING MODES 
Peak, 1st Peak or Track will show on the display.  Press the Πkey to toggle them. 
 
Peak 
Recommended operating mode for stall tools. 
Displays and retains the maximum torque exerted by the tool, as occurs when operating 
the wrench in the tightening direction.  The Peak Mode is used for all power tools and dial 
wrenches. 
 
1st Peak 
Detects the “first peak” of torque exerted by the tool, capturing the initial torque as occurs 
when the torque wrench cams over.  First Peak is used primarily for Click Torque 
Wrenches and cam over screwdrivers. 
 
Track 
Displays torque as it is being applied to the transducer.  Track mode is used primarily for 
verifying calibration of the unit. 
 
E
NGINEERING UNITS 
Shows the current engineering units.  Press the  key  to  cycle  through  the  eight 
possible choices: Kgf m, KgfCm, gfCm, cNm, Nm, FT LB, IN LB, IN OZ. 
 
 
FULL SCALE 
Shows the Full-Scale value of the Torque Shaft.  This is not an adjustable value. 
 
LOW LIMIT 
Use the Low  Limit setting to visually flag the operator when a reading fails to reach a 
desired minimum value. A small down arrow will appear on the screen if a peak is 
captured below the limit setting. 
 
The limit is adjusted by using the navigation buttons to set the first four digits to the 
desired value.  The fifth digit is used to select the decimal point position.  The Up and 
Down buttons under the “Soft” button Change will change the value from 0-9.  Pressing 
the “soft” DIG will scroll through the digit positions.  When the correct value is entered, 
pressing the ENT button will return you to the menu system.

 DESCRIPTION OF FUNCTIONS 13 
When all the digits have been set, press the MEM key to accept the value and return to 
Program Function mode.  Upon the next reading, LO will appear on the display if the 
captured value is less than the low limit 
 
 
HIGH LIMIT 
Use the high limit setting to visually flag the operator when a reading falls over a desired 
maximum value. High limits are set in the identical way as low limits. Please refer to the 
Low Limit section for details. 
 
NOTE: The green LED on the front of the display will flash when a peak is captured that 
falls within the limit setting.
