INTRODUCTION
DESCRIPTION
The AWS-QCM torque tester is designed to provide for a wide range of torque
testing applications in the smallest foot print at a very reasonable price.
Features include an LCD graphics display, built-in battery pack for remote
testing and robust design. A menu based user interface allows for a wide
range of software configurations while keeping the tester easy to use.

SIDE PANEL INPUTS
DC In
The interface for the AC Adapter supplied with the unit. Use this if you plan on
working under Mains power. Use only the AC adapter provided with the unit.
Use of another 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 batteries in this system should last approximately 12 hours when fully
charged. The Low-Battery indicator on the display will illuminate when the
battery voltage is low. Typically, the user will have between 15-30
minutes before the batteries become too weak to power the unit.
2. The batteries are charged any time the system is plugged-in. In Fast
Charge mode, i.e. the unit is plugged in and the power is OFF, charge time
is between 2 and 4 hours depending on battery 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 to be stored for several months, always ensure the
battery is completely charged prior to storage.

RS-232
The AWS-QC display can be connected to a printer, computer or data collector
via its RS232 interface. Every time 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. Cables
are available directly from AWS, or they can be constructed according to the
following tables. AWS also offers various software packages to get your
readings into excel or other programs. Call us for more information

PROGRAMMING & NAVIGATION
The AWS product line has been newly redesigned to provide a consistent
interface throughout the product line. We have made the user interface menu
driven, as opposed to 'hard coded'. This has provided several advantages.
First, once you learn the basics, you can operate any of our products with the
shortest learning curve possible. Second, it allows us to offer a greater array
of functionality than was previously possible. Third, it allows the user the
opportunity to economically upgrade and/or customize the tester at any point
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 will scroll through the options. In the picture above,
pressing the down arrow will scroll through the Modes of Operation. These

include Peak, 1st Peak and Track. The Up Arrow will scroll through the
engineering units.
2. Menu Driven: There are two sets of menus in the display.
a. Bottom right Oval button will scroll through the Tester Operating
Functions. For basic testers, this includes the RUN MODE and MEMORY
(MEM) MODE. Toggling this button will change the functions of the
other soft buttons appropriately.
b. MENU (bottom left oval) will take you to the main menu system.
Shown below is a sample of one menu screen
MENU TREE
Operation Overview: There are 7 buttons on the display face: On/clr, Off, four
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 will take you back
to the previous screen, until you return to the run mode.

Button Operation:
Run Mode (Current mode displayed):
ON: Clears the peak reading if saved, Zero’s the display and erases the
memory location otherwise.
ENT: Save 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: Scroll through the current menu.
Programmable keys: Menu actions. The text varies depending of the active
menu selection.
MENU TREE:
1 PEAK OPTIONS MENU
SEL: Enters menu.
1-1 Auto clear
+, - Set time in seconds.
Auto-clear works in Peak and 1st 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 completely off.
With auto-clear disabled, this 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. Repeatedly press arrow key to scroll from "Off to "9". When the
desired value is shown, press the enter button.
Once the unit is returned to operational mode, AC will show on the
bottom of the display. Because auto-clear is now active, this reading will show

for the user specified number of seconds and then clear the display. From now
on, every reading will clear and be stored automatically into memory.
* Remember auto-clear will not work in Track Mode.
1-2 Filter
+, - 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% through 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 measured in the non-selected direction will be
measured, but not captured as a peak. To reset the sign, either cycle the
power or zero the unit.
With Sign Lock OFF, the tester will capture both CW and CCW torque.
1-5 Edit Limits
High or Low edits that limit.
Limit editing:
Up and Down: Change the digit specified (5 is decimal point, OFF turns
the limit off)
DIG: Changes which digit to edit.
ENT: Accepts changes.
2 SYSTEM MENU
SEL: Enters menu.
2-1 Sleep
+, -: Set time in minutes.
To conserve battery life, the display is equipped with a "sleep" mode,
which sets the limit to standby after a user-settable amount of time has
passed without activity. Press the + key to increase the number of minutes the
unit will wait for input, or the - key to decrease the number. The highest
