BACK PANEL INPUTS
The back of the AWS-4050 contains various interface connections:
Transducer Input (12-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.
A TWIST LOCK CABLE!
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
THIS IS NOT
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
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.
OFF, charge time
RS-232
The AWS-4050 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),

PROGRAMMING & NAVIGATION
ENTERS THE MENU
SYSTEM
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, 1stPeak and Track. The Up Arrow will scroll through the
engineering units.
2. Menu Driven: There are two sets of menus in the display.

Operation Overview: There are 8 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 will take you back
to the previous screen, until you return to the run mode.
Button Operation:
Run Mode (Current mode displayed):
AWS-4050 Guide
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 1stPeak 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 AutoClr 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 AutoClr 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 AutoClr will not work in Track Mode.

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)

DESCRIPTION OF FUNCTIONS
The following is a description of the standard features of the AWS product line.
OPERATING MODE
Current operating mode (Peak, 1st Peak or Track) will show on the display.
Press the Πkey to toggles between them.
Peak
Displays and retains the maximum torque experienced by the wrench, as
occurs when operating the wrench in the tightening direction. The Peak Mode
is used for all power tools and some dial wrenches.
1st Peak
Detects the “first peak” of torque experienced by the wrench, 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.
SELECTING A TRANSDUCER
IMPORTANT NOTE: On power-up, the transducer that is selected will be active
and ready to use. When changing the shaft, you MUST Zero the unit. Do this
by pressing the On/Zero. The shaft capacity can be verified by going to the
Information screen in the Systems Menu (2-4). Full Scale capacity screen is
shown. Press the ENT button twice to return to the run mode.
ENGINEERING UNITS
Shows the current engineering units. Press the key to cycle through
AWS-4050 Guide
the eight possible choices: Kgf m, KgfCm, gfCm, cNm, Nm, FT LB, IN LB, IN
OZ.
FULL SCALE
This screen shows the Full-Scale value of the Torque Shaft. This is not a field
adjustable value.
LOW LIMIT
Use the low limit setting as a means of visually flagging 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 the value from 0-9. Pressing the “soft”
positions. When the correct value is entered, pressing the
return you to the menu system.
DIG will scroll through the digit

ENT button will
Once all the digits have been set, press the MEM key to accept the value and
return to Program Function mode. The next time a reading is taken, "LO" will
appear on the display if the captured value is less than the low limit
HIGH LIMIT
Use the high limit setting as a means of visually flagging 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 ON LIMITS: The green LED on the front of the display will flash when a
peak is captured that falls within the limit setting.
