1 Safety Precautions
Meanings of the "a symbol and a signal terms"
Meanings of the "a symbol and a signal terms" indicated at the top of each precaution.
Note that even an item described in Caution may lead to a serious result depending on the case.
Be sure to observe all precautions, because every one of them describes something important.
Warnings; A precaution about the possibility that mishandling may result in death or serious injury of the user.
Cautions; A precaution about the possibility that mishandling may result in personal injury or property damage.
Warnings
1. Do not apply the torque more than permission load.

3.2 Power Source
This model is using the "Ni-MH 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 an AC/DC adaptor is connected, a display may be a full display,
but while the pilot lamp is on, continue charge.
*Measurement while charging cannot be performed. A plug is pulled out at the time of measurement.
3.3 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 detector
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.)

4 Measuring Method
4.1 The common operation method
1) Attach the suiting bit and socket.
2) Check whether the display is zero.
When it is not zero, zero adjustment ("3.3 zero adjustment" reference) is performed.
3) When required, set up measurement mode and the numerical value of each function.
(5 Convenient function refer)
4) If screw bundle work is done, a torque value will be displayed on the display section.
The measured numerical value is read.
5) Push CLR and carry out a zero clearance.
(If the auto clearance is set up by functional setup, a zero clearance will be carried out
automatically.)
6) When continuing, repeat from 4.
7) If work is completed, please carry out power-source OFF.
(Memory of the contents of each set point is carried out.)
4.2 Ratchet one-way function
Ratchet mechanism
DID-4M or DIW-15M are equipped with the ratchet mechanism.
Rotate the ratchet section and choose RRC fixation (CW), fixation, and RLC (CCW) fixation .
One-way mechanism
DID-05 -- CW/CCW -- both can be measured.
* It can fast forward in the direction of the right (screw bundle)
by roller clutch adoption. A screw can be early turned more to
taking a seat. When you use it, carrying out both-directions
fixation (loosening measurement of a direction etc.), please use
it, substituting for the bit for fixed measurement.
The notes in the case of attaching a bit
When the time of CCW measurement and a bit are fixed
The bit for fixation is used. A bit should unite the portion applied a half, should insert it to the back, and check
whether CW/CCW is being fixed. Work with a bit holder portion so that big load does not take for a detecting
element at this time.
When a one-way mechanism is used by measurement of CW
A one-way bit is inserted.
One-way socket
It is attached to DIW-20/75.
If it equips with this socket, in case a screw bundle will be performed, if it carries out by the fast forward
mechanism (one-way socket) and a main part is turned several times after that until a screw arrives at the bottom,
bolting and measurement can be performed simultaneously.
(Since the one-way clutch is being used for an internal mechanism, in a lock and the return direction, the direction
with a bundle becomes free.)
When you use a one-way socket by DIW-75, use it with the torque of 500 kg-cm or less .
It has this portion and attachment and removal of a bit
are performed. If it works with other portions,
exaggerated torque may start and a sensor portion may
be damaged.
