Tohnichi DOT Analog Torque Wrench Tester

Tohnichi DOT Analog Torque Wrench Tester

Features
Dial indicating torque wrench tester with mechanical loading device.
Manual-operated analog type torque wrench tester
Easy-to-read large dial face (φ140)
Since torque wrench is designed to set horizontally, wrench weight correction is not necessary.
Pole plate available for all models, which helps horizontal setting of torque wrenches.
Torque wrenches can be calibrated easily by rotating the handle.
The loading device is designed to apply load accurately against the effective line of torque wrench, which maintains a stable calibration conditions and prevents individual errors.
For markets outside Japan, our products are manufactured to both metric standards of measurement (kgf, cm, etc.) and American standards of measurement (lbf, in, etc.).

DOT Torque Wrench Checker measure torque values accurately by the use of the amplified twisting of the torsion bar set on the dial gauge. DOT Torque Wrench Checker consists of a torque meter and a loading device (to apply force to the torque wrench), which contribute to high accuracy and user-friendly operations. Since DOT Torque Wrench Checker is low weight and small in size compared with conventional testers, operators can check torque wrenches easily.

Handling Instructions
a) There is no need to fix the checker onto the table. Place the checker horizontally on the table.

b) In case of the square drive head: Insert the square drive of the torque wrench into the socket. If the square drive is small, use the furnished socket between the square drive and the socket. In case of the spanner head: Choose the hexagon male socket that matches the size of the spanner from the furnished sockets. Insert the square drive of the hexagon male socket into the socket, and fit the spanner to the width across the hexagon.

c) Slide the pole on the loading plate so that it is aligned to the effective length line of the torque wrench, and lock the pole.
d) Turn the handle clockwise, so that the pole presses on the effective length line of the torque wrench. With the turning of the handle, the pointer on the dial indicates the appliedtorque.

e) In case of the preset torque wrench with scale or without scale, the pointer will suddenly lower after continuous increase when the preset torque is reached. Read the value on the dial just before the pointer lowers. In case of beam and dial type torque wrenches, read the value on the dial as it is. Depending on the shape of torque wrench, there may be too much space between the pole and the handle of the torqure wrench. In such case, remove the pole once and put it on the opposite sides to make up for the space

Maintenance and Handling Notes
Maintenance
a) Avoid placing the checker in dusty places.
b) Inspect the checker approximately every two months, although the period may depend on the frequency of use. Inspection guarantees the accuracy and the life of the checker. It is not necessary to apply lubricant on the checker. Handling Notes
a) Place the checker horizontally whenever used.
b) Handle with care, since the checker is an elaborate product. If the checker has been subjected to violent vibration or dropped on the ground, check the accuracy in any case.
c) Avoid using the checker in places subject to extreme vibration. Accurate checking can not be obtained.

Measurement Method For calibration of DOT models, use the DOTCL Calibration Kit. The DOTCL calibration kit is designed exclusively for Tohnichi DOT Torque Wrench Testers. It is not recommended for use on other equipment. There is no need to fix the kit to a workbench, since the unique design stabilizes the unit itself. The DOTCL kit tests in both the clockwise and counterclockwise directions.

1) Set the DOT tester on a sturdy workbench in a vibration-free environment.
2) Assemble the calibration stand and set.
3) When hanging the wire, carry out a zero adjustment according to the following:
Turn the scale plate so the needle is pointing toward zero.
4) Hang the scale holder from the top of the wire.
5) According to the measured value, add additional weights to the scale holder for calibration.
