3.2 Selection of Joint for Measurement
Some "joint for measurement" is attached to this product.
At the time of measurement of a tool, the joint corresponding to a tool is surely used.
3.2.1 SJ Joint
SJ joint is used for measurement of an electric driver.
In case joint is chosen, tolerance level is checked and it is cautious of exaggerated torque enough.
SJ joint (coiled-spring compression system)）
SJ50 （MAX 5N・ｍ）SJ10K（MAX 1N・ｍ） It attaches to CD100. Cap bolt portion H6
SJ10 （MAX 1N・ｍ） It attaches to CD10. Cap bolt portion H5
The bolt omission prevention function was newly
carried in joint. By attaching an omission
prevention screw, if a bolt separates from a plinth, it
will race, and it does not decompose and trouble is
not caused to work. （However, when it continues
racing, a ridge may be worn out and torque value
may change.）Moreover, by wear, the metal fatigue,
etc. of a screw, where a spring is closed, it is left,
and a bolt may jump out with the pressure.
New joint which served also as the measure against dangerous prevention in that case. (PAT,P)
The cautions on use
The load more than the measurement range is not applied by any means.
It checks before use whether grease is attached to bolt and bearing.
After use is kept where a spring is surely loosened.
The number of times of an exchange standard is about 2500 times.
When the following condition comes out, use is stopped and new joint is used.
When there is wear of a bend and a ridge
When there is sound etc.

3.3 Cautions at Time of Installation
At the time of measurement, it installs so that a circuit tester main part may not move.
When especially high torque starts, A fixed knob is used.
3.4 Power Source
This model is using the "Ni-cd charge battery." Charge it with an AC/DC exclusive adaptor.
The display of battery residual quantity is displayed on the display upper part.
The meaning of a display
Display
Contents
There is battery residual quantity.
Battery residual quantity has decreased. It charges soon.
When using many lamps, such as a yes-no decision, and buzzers,
it charges a little early.
There is almost no battery residual quantity. It charges urgently.
When there is no battery residual quantity, a power source is shut off immediately.
Charge uses an AC-DC exclusive adaptor by all means.
If key operation is not performed for 10 minutes, a power source will be in an OFF state automatically.
When you turn off the power, push an ON/OFF button lightly for about 1 second.
* If anAC/DC adaptor is connected, a display may be a full display,
but while the pilot lamp is on, continue charge.
3.5 About zero adjustment
At the following, this tester is performed zero adjustment automatically.
1.When power is switched on 2.When measurement mode is changed
(When torque started during this movement,
it becomes impossible for 0 points to shift, and to do a normal measurement.
At the time of power supply injection and the measurement changing,
confirm that torque does not started.)
Moreover, zero points might shift when zero points do not return.
In that case, zero points adjustments by the following methods.
1. Check that torque has not started a detecting element.
2. If CLEAR is kept pushed, Red LED will switch on the light.
If the light is switched on, the CLEAR button will be detached promptly.
3. Red LED will disappear, display will be zero, zero adjustment is completed.
*When continue pushing it in a state with the red LED, display it with
and become all elimination of memory data. (Leave Red LED unattended. It will be zero.)

4Measuring Method
The concrete measuring method of various tools is explained.
4.1 Measurement of Electric Driver
The torque of the electric driver whose set torque is possible of operation is measured.
In the case of the electric driver which performs impact operation, it may be unable to measure normally.
4.1.1 Check of Torque, and Selection of Measurement Joint
The standard of the output torque of the electric driver to measure is checked, and it checks whether it is in the
measuring range of a tester. Especially when you use "CD-10M", be careful. * CD-10M are a maximum of 1
N-m=10kgf・cm.
Next, SJ joint to be used is chosen. First, it checks whether the torque of the standard of an electric driver is
in the tolerance level of SJ joint. Next, the bit of an electric driver and the screw of SJ joint head to measure
confirm whether it gears exactly. When a bit does not suit a screw well, it becomes the cause of coming-out or
screw-head breakage. In this case, a bit is exchanged for other things, or the kind of screw is changed and it
corresponds. Moreover, if it exchanges for the attached bit for measurement, it is also possible to remove the
screw of the head of SJ joint, and to measure as it is.
4.1.2 The method of measurement
1. Install SJ joint in a torque detecting element.
(SJ joint is fixable using the tapped hole for fixation of a
detecting-element nail portion.)
2. Press a power-source key and switch on a power. (A power source
is switched on after checking that load is not applied to a detecting
element, since zero adjustment is performed at this time)
3. Check whether measurement mode is "PP" peak interrupt mode.
Measurement mode is changed into "PP" when "PP" is not displayed on display (3.1.2 references).
4. The fit of the bit of an electric driver is carried out to the screw of SJ joint head,
operate an electric driver, fasten, and perform lump operation. It checks whether the
spring of SJ joint is loosening at this time. When you are not loosening, please be
sure to start measurement after loosening.
※Before operation, a display checks in "0." When it is not "0", a clear button is
pushed and it is made "0."
5. If it binds tight and operation finishes, the torque value of a display board will be
checked.
6. Loosen the spring of SJ joint using inversion operation of a driver.
7. If the "CLEAR" button is pushed, it will be in the state where a display is cleared and measurement is possible
again.
