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.
