Service and Warranty
Overload Capacity Caution
ASG, Division of Jergens, Inc., warrants to the original purchaser buying the ASG DTT-L meter with the intention of use rather than
resale, for a period of 1 year. ASG will replace those items found to be defective or otherwise fail to conform, or at ASG’s option
repay the price paid for the item. The buyer’s remedies with respect to any item found to be defective or otherwise not conforming
shall be limited exclusively to the right of replacement or repayment. In no event shall ASG be liable for any incidental, special or
consequential damages or for damages in the nature of penalties.
DISCLAIMER: Seller makes no other warranty what-so-ever, expressed or implied, and all implied warranties of merchantability and
tness for a particular purpose are disclaimed and excluded from this transaction and shall not apply to the goods sold hereunder.
The ASG DTT-L meter is an electronic instrument and should be treated with the same care given any sensitive electronic instrument.
Avoid dropping the unit or dropping items on the unit. Avoid high shock loads to the transducer. Use the proper driver adapter when
using clutch type power tools.
Do not exceed the capacity of the unit. The overload capacity of a DTT-L meter is 200% of its maximum load capacity. If the meter is taken
over capacity, a warning tone will sound, the word “OVERLOAD” will ash on the LCD, and the unit will LOCK until the RESET button is
pressed. Immediately stop applying torque when the overload warnings are observed. A unit subjected to overload or subjected to harsh
conditions, such as use with an impact tool, will not be covered under warranty.

Below is a list of all rundown adapters ASG offers for the DTT and DTT-L Series
• Rundown adapters are included with the DTT torque testers. See charts in DTT manual on page 6 for more information.
• Rundown adapters are not included with the DTT-L torque tester, choose the needed rundown adapters from the chart below
when ordering the tester.
* ASG Adapter #66612 comes with two springs covering torque range from 1.3-5.0 lbf.in (0.15-0.56) and 4.5-26.0 lbf.in (0.51-2.94 N.m)

Usage
Procedure for Manual Torque Drivers
• Attach a proper adapter to connect the driver to the 3/8” female square.
• NOTE: It is NOT recommended to use the power tool adapters to calibrate hand torque tools.
• Select FIRST PEAK mode using the MODE button. Press the RESET button if the display is not at 0.
• Turn the driver or wrench clockwise or counterclockwise until the “break” point is reached.
• In FIRST PEAK no other reading can then be displayed until the reset button is pressed.
• The LCD display will show the torque that the driver or wrench is set at. Note the reading or write it down. To enter it into the
DTT-L memory press the ENTER/MEM button. If you are testing several tools, note the memory numbers of the readings for the
various tools. This number is in the upper right hand corner of the LCD. The unit can save up to 200 readings. After that, no
further readings can be entered until the memory is cleared.
• If the torque is not correct, adjust the tool. Repeat the test. When the reading is proper, perform the test several times to be sure
the readings are consistent. The proper reading may be an average of several readings.
Procedure for Power Screwdrivers
• Put the appropriate rundown adapter into the unit’s female 3/8” square socket. It allows the power tool to reach its working speed
before tightening up and causing the clutch to operate.
• Run the tool in reverse to make sure the adapter is unwound. Do not disassemble the driver adapter.
• Make sure the unit is in PEAK mode. If it is not, use the MODE button to select PEAK mode.
• Press the ZERO button to be sure the display is at 0.
• Run the tool forward until it shuts off. The reading on the display will be the torque setting of the tool’s clutch. Note the reading or
write it down.
• To enter it into the units memory, press the ENTER/MEM button. If you are testing several tools, note the memory numbers of the
readings for the various tools. This number is in the upper right hand corner of the LCD. The unit can save up to 200 readings. After
that no further readings can be entered until the memory is cleared.
• If the torque is not correct, adjust the clutch. Repeat the test. When the reading is proper, perform the test several times to be sure
the readings are consistent. The proper reading may be an average of several readings.
• Always unwind the rundown adapter after each test. Do NOT leave the spring under tension while not in use.

While operating the tester, it may be necessary to zero the display so that residual torque does not become part of the measured
reading. Press and release the ZERO key.
You can choose from the following modes of measure: Track, First Peak, and Peak. To change the display mode, press the MODE
key. Each time the MODE key is pressed, it will select the next available mode until the tester returns to its original setting.
You can choose from the following units of measure depending on the capacity of your tester: N.mm (not available on the DTT-L 500),
N.cm, N.m, kgf.cm, kgf.m, lbf.in, and lbf.ft. To change the display units, press the UNIT key. Each time the UNIT key is pressed, it will
select the next available unit until the tester returns to its original setting. The DTT-L automatically converts readings as new units of
measure are selected.
NOTE: All units may not be displayed depending on tester capacity.
