OPERATION

DISPLAY OPERATION

Button Function:

Powering on and off
Press any Key to turn the unit on.
Press CLR and ENT simultaneously to turn the unit off.

ENT
Sends the current reading to the serial port and clears the current peak.

MDE
Displays the current mode for 1 second. Pressing MDE again while the mode is
displayed will change the mode. Any other button will return to sample mode.

ENG
Displays the current units for 1 second. Pressing ENG again while the units are
displayed will change the units. Any other button will return to sample mode.

CLR
Clears the current peak or zeros the transducer if no peak is current.

ENT+CLR
Turns off the display. Press any key to turn on the display.

MDE+ENG
Displays the program menu. See below.

SAMPLE MODE

Sample mode is the normal operating mode used for measurement. When a
measurement is taken, the current transducer sample or current peak is
displayed. If a peak is inside the low and high limits, or the limit(s) is/are off,
the LED will light up green. Otherwise, the LED will light up red to warn the
user that the measurement is out of limits.

PROGRAM MENU

The program menu alternates display of the item name and the current setting.
The program menu will time out after 5 seconds without a button press. All
settings will be saved and the display will return to sample mode.

AWS-QCGuide

OPERATION 4

Buttons for menu navigation:

Up (ENG): Go to the next item.
Down (MDE): Go to the previous item.
CLR: Exit back to sample mode and save all settings.
ENT: Change the current item.

Menu Items: (Some models may not have all menu items)

A.C.: Autoclear time, in seconds. Off, 1 - 9

FILT: Peak filter frequency response, in hertz. 125, 250, 500, 750, 1500.

PPER: Minimum peak, percentage of full scale. 2 - 50.

S.L.: Sign lock. On, Off.

LOW: Lower limit. A setting of 0.000 disables the limit. Press ENT to enter the
number edit mode. (see below)

HIGH: Upper limit. A setting of 0.000 disables the limit. Press ENT to enter the
number edit mode. (see below)

F.S.: Full scale in the current units. Not editable.

SLEEP: Inactive time to sleep, in minutes. Inactive time is when no buttons are
pressed and the transducer is in zero blanking. Off, 1 - 20.

NUMBER EDIT MODE

The current digit or decimal point flashes. Number edit mode never times out.

ENT
Save the current digit and go to the next digit. After editing the digits, the
decimal point can be moved. After the decimal point is saved, ENT exits
number edit mode and saves the number that was edited. During the decimal
point edit, the decimal point can be moved to a position where all of the digits
flash. If ENT is pressed at this point the number saved will be 0.000.

Up (ENG)
Increases the current digit or moves the decimal point to the right.

Down (MDE)
Decreases the current digit or moves the decimal point to the left.

AWS-QCGuide

OPERATION 5

CLR
Cancels number edit mode and restores the previous number.

SIDE PANEL INPUTS

The side of the AWS-QC contains two interface connections:

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 batteries are trickle-charged any time the system is plugged­in, and take about 8 hours to fully charge. The unit does not indicate when
it is charging. 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.

AWS-QCGuide

OPERATION 6

RS-232

The AWS-QC display can be connected to a printer, computer or data collector
via its RS232 interface. Values are sent via RS-232 every time the unit auto­clears or the ENT/clr button is pressed. Data cables can be made from the
drawing below or purchased from AWS. We also offer various software
packages to retrieve data from our units, including the QC.

DESCRIPTION OF FUNCTIONS

The following is a description of the standard features of the AWS product line.

OPERATING MODE

Peak

Displays and retains the maximum torque exerted 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.

ENGINEERING 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

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.

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.
