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

4) Auto Memory
With Auto Memory turned on, the torque reading is automatically entered into the DTT memory
each time a new reading is taken. It is not necessary to press the ENTER button each time. This
will function only in PEAK MODE and only with torque readings applied in the clockwise direction.

5) Auto Reset Mode
Auto Reset is used to automatically reset the meter and display the next torque reading without
having to press the RESET button each time to clear the previous reading. Auto reset can be
used in PEAK mode only. Auto Reset can be used with Auto Memory to automatically enter the
reading into memory and reset the reading.
If a high torque value is selected for the threshold, say 20 lbf.in, and a lower torque is applied
first, say 10 lbf in, the 10 lbf.in will be displayed on the LCD. If the next reading is 15 lbf.in it will
also be displayed. Until you reach the threshold the DTT meter acts as it does in peak mode. Any
reading higher than the previous reading will be displayed. A lower reading will not register. Once
the threshold has been reached any torque reading that is higher than the threshold will be
displayed whether it is higher than the previous reading or not.

Enter Percent
of 100 lbf.in**
Old Data : 00%
Enter New : 00%
*This % number will depend on which model DTT meter is used. See page 26 for other
models. This will be a minimum % of the torque units shown. The torque units can not
be changed here. The torque units can only be changed in the calibration menu.
**This number is the maximum torque value of the meter. The maximum torque of the
DTT-100 is 100 lbf.in (See page 26 for other models) therefore, For the DTT-100 the
minimum threshold that can be set to act as the “trigger” to over write the existing
reading with the new reading is 2% of 100 lbf.in, or 2 lbf.in. Any %, from 2% to 99%,
can be selected, for the DTT -100, which would then represent 2 to 99lbf.in.
To set up the threshold to 15 lbf.in, on a DTT-100 you would use UP or DOWN to enter 15%. 15
lbf.in will be 15% of 100. Press UP or DOWN to change Enter New : 00to ENTER NEW : 10
You do not have to worry about which value will change. Only the zero underlined in the ENTER
NEW line will change. No other number will change until ENTER is pressed. After you change the
00 to 10 and press ENTER you will see:
AutoReset min 2%

see:
Before you save the setup make sure you have reselected PEAK as your default setting. Follow
the Save Setup instructions. The word “AUTO” will now show between the time and the memory
number at the bottom of the LCD when the unit is turned on.
To turn Auto Reset off, enter the main menu, select set up, select Auto Reset Mode and press

Before you save the setup make sure you have reselected PEAK as your default setting. Follow
the Save Setup instructions. The word “AUTO” will no longer show on the LCD in the normal
operating display.
Caution, If Auto Reset is set too low you could experience “kick back” in the
driver adaptor when the tool shuts off. This can cause erroneous low torque
readings. If you see what seems to be very low reading based upon the
torque the tool is set at, check the direction arrow on the LCD. If it shows
counter clockwise, set the threshold higher, closer to the torque setting of
the tool.

5) Go-No Go Mode
Go-No Go mode is used to set a range or “window” for acceptable torque readings. This can be
used only with the meter in PEAK or FIRST PEAK modes. When a torque falls within the range the
meter will show the word “GOOD!” on the LCD just above the time. Any torque reading outside
this range, higher or lower, will cause the LCD show message “NO GOOD!” This range can be
set between 2 and 99% of the maximum torque of the meter. There is also a sound option that
will cause the meter to “beep” when a reading is within the range.
Say you wish to test a number of hand torque drivers that are supposed to be set at 15 lbf.in.
You may say that as long as the driver is above 13 lbf.in but below 17 lbf.in the driver is
acceptable.

*This number is the maximum torque value of the meter. On a DTT-100 this is 100 lbf.in. The
minimum lower level that can be set up is 2%. 2% of 100 lbf.in will be 2 lbf.in. (See page 26 for
the min torque value for other models). Any number from 2 to 99 can be selected which would
then represent 2% to 99% of 100 lbf.in on a DTT-100, or 2 to 99 lbf.in.
To set up the lower level to 13 lbf.in, on a DTT-100, you would use UP or DOWN to enter 13%.
13 lbf.in will be 13% of 100. Use UP or DOWN to change Enter New : 00to ENTER NEW :
