Button Functions (left to right)
Button (#1) MENU/RESET/ESC
In normal operation, pressing the MENU/ RESET/ESC button resets the torque readings to zero in
either the PEAK or FIRST PEAK mode.
In TRACK MODE, pressing the MENU/RESET/ESC button takes you into the MAIN MENU. At any
other place in the menu this button acts as an ESCAPE button to take you back to the previous
screen.
Button (#2) DOWN/MODE
In normal operation, the DOWN/MODE button is used to change the MODE setting of the DTT
meter. Each time the button is pressed the mode will change from TRACK mode to PEAK, or from
PEAK to FIRST PEAK, or from FIRST PEAK to TRACK.
Within the menus this button is used to scroll DOWN to the next selection.
When inputting a number to set up the Date & Time, the Go, No-Go feature, the Auto Reset Mode
or calibration, pressing this button will decrease the number by 1 digit.
Button (#3) UP/UNIT
In normal operation, pressing this button changes the torque units of the meter. Pressing the
button will scroll through the 9 choices. Kgf-cm, gf-cm, Kgf-m, mN-m, cN-m, N-m, ozf-in, lbf-in,
lbf-ft, in this order. Do not attempt to back up by pressing the DOWN button, you will only
change the mode.
Within the menus this button is used to scroll UP to the next selection.
When inputting a number to set up the Date & Time, Go, No-Go feature, the Auto Reset Mode or
calibration, pressing this button will increase the number by 1 digit.
Button #4 MEM/ENTER
In normal operation, pressing the MEMORY button enters the torque reading into the DTT meters
memory.
In all other menus this button is used to ENTER the selection, or perform the action selected.
MENU DETAIL and INSTRUCTIONS
The DTT meter is menu driven. Please note that text actually seen on the LCD may have asterisks or other
characters used for spacing. When an asterisk is noted here it is used to call attention to a specific item
and is not part of the display. If confused or lost in a menu, press the ESCAPE button until you return to
the operating display and start over. When pressing the buttons to navigate in a menu or increase or
decrease a value, the button must be pressed and released once for each action. You will hear a beep
each time a button is pressed. The button may not be held down to increment faster.

Menu 4: Calibration
The Calibration menu is used when the DTT meter requires re-calibration. The System units are
selected here. ASG recommends annual re-calibration by qualified personnel. Re-calibration may
also be necessary if a check reveals that the DTT meter is out of spec. Calibration, or a
calibration check can only be performed with the DTT operating on battery power. Do not
calibrate the unit with the battery charger attached.
It is not necessary to be in the calibration menu to check the meter to see if it is in spec. Attach
the proper calibration arm, or wheel and hang enough weight to check the DTT meter at is
maximum torque capacity. Allow the system to stabilize. Check the reading on the LCD and
determine if it is within +-.2% of maximum capacity. (For a DTT-100 this will be +-.2 lbf.in, for
other models check page 26) Check the DTT meter at several other points to insure that the
meter is linear. The readings must be within +-.2 lbf.in of the actual torque applied.
If calibration is necessary make sure the DTT meter’s battery is charged. Turn the meter on and
let it warm up for 30 minutes. The meter cannot be calibrated with the battery charger attached.
The Calibration Menu is protected by a 4 digit password. The password is 9991

within that range. When the reading is within the allowable limit change the amount of weight
and repeat the process at a different torque reading. Check the readings at several other points

Menu 5: Communication
This function is used to download the stored torque readings in the DTT Meter’s memory to a PC,
via the RS-232 to USB Serial bridge cable, or the RS-232 to DB9 Serial cable supplied with the
DTT meter. Your computer must have the ASG Torque Memory Loader software, found on the
CD-ROM provided with your DTT meter, installed on your PC. NOTE You must also load the driver
(s) for the USB serial bridge cable if your PC does not recognize it. These drivers are on the CD
supplied with your unit.
To download data, connect the USB connector to a USB port on your PC, or the DB9 Serial plug
to a serial port on your PC. Connect the 6pin DINN connector to the RS-232 port marked on the
side of the DTT meter. This can be found on the side of the meter with the power switch. Make
sure the ASG Torque Memory Loader program is turned on in your computer.
Select 5) Communication and press ENTER. You will see:
