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 memory press the “MEM / ENTER”
button. If you are testing several tools note the memory numbers of the readings for
the various tools. This number is in the bottom 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. See the operating manual for instructions on downloading and
clearing the readings in the memory.
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 stable. The proper
reading may be an average of several readings.

PROCEDURE FOR POWER SCREWDRIVERS
Put the driver adapter into the unit’s female 3/8” square socket. This is also called a
joint simulator. 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. Take care not to
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 “RESET / ESC” button to be sure the display is at 0Run 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 “MEM / ENTER” button. If you are testing several tools note the memory
numbers of the readings for the various tools. This number is in the bottom 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. See the operating manual for instructions

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 stable. The proper
reading may be an average of several readings. ALLWAYS UNWIND THE DRIVER
ADAPTOR AFTER EACH TEST. DO NOT LEAVE THE SPRING UNDER TENSION
WHILE NOT IN USE

INSTRUCTIONS FOR USING THE DRIVER ADAPTER
Use an adapter that has a higher capacity than the tool you are using. Before using
the adapter, make sure the thread is unwound but engaged. Turn the shaft by hand to
make sure the thread is turning smoothly and the bearing is also turning smoothly.
Refer to the pictures below to identify the various driver adapters and springs to
determine the proper set up to obtain the correct match for measuring torque
