INTRODUCTION 
DESCRIPTION 
The Portable Torque Test Stands are designed specifically to test the torque output of a variety of 
hydraulic wrenches.  The Test Stand includes a LCD graphics display, battery powered for remote 
testing, and movable reaction devices for a variety of tools. There are a variety of reaction devices 
available, contact us to ensure reaction devices are suitable for your specific tools.  The display 
has serial output for use with a serial printer or Windows PC (with any terminal emulator program 
– see Serial Settings in this manual – or special software available only from Auditor). Optional 
instruments are offered providing larger screens and even data collection if required. 
 
NOTE:  The AHCTS series of test stands are available with a wide range of configurations that are 
driven by the specific users’ needs.   You may notice many of the images contained in this manual 
may vary in reference to the actual unit that was configured. However, Auditor branded 
instruments feature similar user interfaces and menu structure.  When appropriate, an additional 
manual specific to the instrument configured on the stand may be included in the shipping 
documents.

BACK  PANEL INPUTS  
The back of the display unit contains various interface connections: 
 
Transducer Input (10-pin connector).  
 
To install or remove the cable simply push in or pull out.  Do this by gripping the outer 
metal case of the cable and NEVER from the cord itself. THIS IS NOT A TWIST LOCK 
CABLE!  IMPORTANT: REMOVE CABLE FOR SHIPPING & TRANSPORTING!! 
 
DC In 
The interface for the AC Adapter supplied with the unit.  Use this if you are working under 
Mains power.  Use only the AC adapter provided with the unit.  Use of any other power 
source will void the warranty and may cause severe damage to the display. 
 
RS-232 
If you are downloading to a printer, data collector, computer, etc., this is the mini-plug 
interface for the RS-232 cable.  Values are sent via RS-232 every time the unit auto-clears 
or the ENT/CLR button is pressed 
 
 
CHARGING THE BATTERIES 
1.  The battery life is approximately 12 hours when fully charged.  The Low-Battery 
indicator on the display will illuminate when the battery voltage is low.  After this 
indication the user has approximately 15-30 minutes before the batteries will no 
longer power the unit. 
2.  The batteries charge when the system is plugged-in.  In Fast Charge mode ( i.e. the 
unit is plugged in and the power is OFF), charge time is 2 - 4 hours depending on 
charge level. The green LED on the front panel will flash when the battery is charging 
and turned off. It is recommended the tester be plugged in when not in use.  This will 
not harm the unit and will increase battery life. 
Note: If the tester is stored for several months, ensure the battery is completely charged 
prior to storage.

RS-232 
The display can be connected to a printer, computer or data collector via the RS232 interface. When 
a reading is accepted into memory, a peak is cleared, or data is transmitted via the Print Data 
menu(s), it is transmitted via the RS-232 port.  To download the readings, go to the DATA MENU. 
Auditor has special software available to download the readings, or they can be viewed with a 
terminal emulator program such as HyperTerminal (included in all versions of Windows before Vista 
under Start>Programs>Accessories>Communications), or a free terminal program such as PuTTY.

The Auditor product line has been designed to provide a consistent interface, the User 
Interface menu is driven, as opposed to hard coded.  This has provided several 
advantages: 
  Allows user to operate any of our products with the shortest learning curve 
possible.   
  Offers greater functionality than previously possible.   
  User can economically upgrade and/or customize the tester in the future. 
 
The four buttons on the bottom row are programmable or Soft Buttons.  The functionality 
of the buttons will vary with the current selection.  There are two ways to change settings, 
or otherwise gain access to the operation of the tester: 
 
1.  Live Programming: Where the soft buttons have text above them, pressing the 
button scrolls through the options.  In the picture above, pressing the down arrow 
scrolls through the Torque Modes.  These include Peak, 1
st Peak and Track.  The Up 
Arrow scrolls through the Engineering Units. 
2.  Menu Driven: There are two sets of menus in the display.   
a.  Bottom right oval button scrolls through the Tester Operating Functions.  For 
basic testers, this includes the RUN MODE and MEMORY (MEM) MODE.  
Toggling this button changes the functions of the other soft buttons appropriately. 
b.  MENU (bottom left oval) takes you to the Main Menu system.  (Shown below is a 
sample of one menu screen)

Operation Overview: There are eight buttons on the display face: Off, On, four (4) 
programmable or ‘soft’ buttons, Zero and Enter.  The exact function of the soft buttons is 
defined by the bottom two rows of text and will vary depending on the current mode of 
operation. Pressing the ENT button takes you back to the previous screen. 
 
Button Operation: 
Run Mode (Current mode displayed):  
ON: Clears the peak reading if saved, otherwise zero’s the display and erases the 
memory. 
ENT: Saves current reading in memory if memory is on and clears the peak reading. 
 
Memory Mode (MEM displayed instead of Run): 
ON: Goes to Run Mode without erasing memory location. 
ENT: Scrolls to next empty location. 
 
Either Mode: 
RUN -> MEM: (soft button) Changes the mode of the arrow buttons. 
Up and Down: (soft buttons) Units and Mode respectively for RUN; Memory location for 
MEM. Depends on the right programmable button. 
MENU: Enter menus. 
 
MENU Operation: 
ENT: Previous menu. 
Up and Down: Scrolls through the current menu. 
Programmable Keys: Menu actions.  The text varies depending of the active menu 
selection.

1-1  Auto clear 
+, - Set time in seconds. 
 
Auto-clear works in Peak and 1
st Peak modes, freeing the operator from manually clearing 
the display after taking a reading. Auto-clear can be set from one to nine seconds, or 
turned completely off. 
 
With AutoClr disabled, the reading will continue to display until the operator stores it by 
pressing the ENT button, or clears it by pressing the “On” button. 
 
Pressing the + key will change Off to a value of 1, referring to the number of seconds 
the system will hold a reading on the screen before clearing. Press arrow key to scroll 
from Off” to 9. When the desired value is shown, press the enter button. 
 
When unit is returned to operational mode, “AC” will show on the bottom of the display. 
Because AutoClr is now active, the reading will show for the specified number of seconds 
and then clear the display. At this point, all readings will clear and be stored automatically 
into memory. 
Note: AutoClr will not work in Track Mode.

     +, - Set filter value in Hz.  
125, 250, 500, 1000, 1500 & 2000. 
 
 
 
 
1-3  Peak Blanking 
+, - Set blanking in percent of full scale. 
Peak Blanking sets the minimum threshold at which torque is captured as a peak. 
Pressing the + and - buttons will toggle this from 2% to 50% of Full Scale. Pressing the 
ENT button will accept this value and return to Run Mode. 
 
 
 
1-4  Sign Lock 
+, - Toggle On or Off. 
The Sign Lock feature allows the user to select the torque direction of the peak to be 
captured. With Sign Lock ON, the initial direction or sign is the default direction. Any peak
