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/ESC 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 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 upper right hand corner of the LCD. The unit can save up to 500 readings. After that no

further readings can be entered until the memory is cleared. See the main menu section starting on page 11 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 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. 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. 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 RESET/ESC 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 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 upper right hand corner of the LCD. The unit can save up to 500 readings.

After that no further readings can be entered until the memory is cleared. See the main menu section starting on page 11 for

instructions on downloading and clearing the readings in the memory.

• 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.
