This product is a digital torque wrench for tightening purpose. Upon reaching the set torque, a buzzer goes off and LED
turns on to signal tightening completion. Applied torque will be indicated on the digital display as well as on LED indicator.
・The indicator display enables the user to see the setting torque and the actual torque being applied at the same time.
・Applied torque will be directly reected on the display in a timely fashion.
・Can register maximum 10 different torque settings (Target torque/Upper limit value/Lower limit value).
・Multiple units of measure selection through keypad setup: N ･ m, kgf ･ cm,kgf ･ m,lbf ･ in,lbf ･ ft.
・Maximum 50 of tightening data can be stored in the internal memory, and transferred to PC with RS232C cable (Optional).
・AA batteries are used (available in the local market).
・Can be used for re-tightening inspection method as well as loosening torque inspection method.

① Auto Zero function
In RUN mode, push Clear key to activate Auto Zero function. Displayed torque value will be cleared to zero (Auto Zero
function will activate only when the displayed torque is within 7.5% of the maximum torque value). If the value is 7.5% of
the maximum torque or more, it may show "Err9". Please refer to P25 "Error Message" for details.
② Auto Memory/Reset
Tightened torque value will be stored in the internal memory automatically after the set timing (selectable between 0.1 – 5
seconds) and the counter will be forwarded to the next. When the communication cable (No.585) is connected to CPT, torque
data will automatically be output through the cable as auto memory saves the torque value. If you do not need to activate Auto
Memory/Reset, set it at 0.0 second.
Auto memory/reset will be activated only when the torque reaches beyond the lower limit value. Also, if the target torque
or upper/lower torque limit is set as Zero values, this function will not be active.
③ Mute
Set "OFF" on Buzzer setting. Buzzer will not go off.
④ Auto Power off
Power will be automatically turned off after 3 minutes without any key operation or any torque load (7.5% or lower of the
maximum torque capacity).
In case of "LoBATT" alarm (low battery) condition, it turns off after 1 minute without use.
⑤ Residual battery display
It indicates the residual battery amount by LCD indicator.
⑥ Over torque alarm
When the applied torque exceeds 105% of the maximum torque capacity, the display blinks between " －－－－ " and the
torque value and the buzzer goes off. In this case, the measured data will not be saved by the manual operation.

※ All the units except N.m, calculate the torque value based on the unit conversion table on P18.

① Preset tightening mode "PRESET" （default）
Set the target torque and range,and tighten up to that torque.
Set the tightening mode to "PRESET" (default).
This mode is for simple tightening operation that does not require a judgement or recognition of tightening direction.
Blue LED shows the target torque range.
(Please refer to P19 for setting procedures.)
Example)
When you set target torque 100N ・ m and target range 5%, then the blue LED blinks in the range of 100-105N ・ m .
○ Selecting the target torque
PEAK mode (set the memory counter to 01-50).
Press MD key to proceed to torque setting.
Use ▲▼ key to select pre-registered torque value and
press MEM key to conrm.
When there is measured data remained in the memory,
you cannot change torque setting.
Please clear the measured data before change.
Press MD key or C key to proceed to measuring mode without changing the torque setting.
① Continuous display (RUN mode)
Set the memory counter to "00". The applied torque will be directly displayed without peak holding, and torque value will
be returned to zero as you release loading.
Indicator display will not be used.
② Maximum value display (PEAK mode)
Set the memory counter between "01 – 50". Displayed value will increase as torque is applied, and captures the
maximum value (PEAK torque) and remain displayed even after releasing loading. The indicator display will also be held
at PEAK value.
(Please refer to P16 for operating instructions)
③ Tightening mode
PEAK mode has two different tightening settings.
Both tightening modes can register up to 10 different torque values A through J (target/upper/lower torque value).
・Preset tightening mode “PRESET” （default）
Use it as adjustable style of torque wrenches. First, set the target torque and target range (%). As you apply torque, the
red LED starts to blink and move toward right. When it reaches the target range, the blue LED starts to blink and the
buzzer goes off. When it reaches out of the target range, the red LED starts to blink and a buzzer goes off-and-on for
alarm to prevent over-torque.
(Please refer to P10 for operating instructions and P19 for setting procedures.)
・Judgement Tightening mode "JUDGE"
A judgement will be given after tightening.
Set the lower limit torque, and the upper limit torque, and the judgement will be given after tightening. As torque is
applied, the red LED indicator starts to blink and moves toward right. Upon reaching the lower limit torque, the blue LED
blinks and the buzzer goes off to signal completion. When it exceeds the upper limit, the red LED starts to blink again and
another buzzer goes off for alarm.
(Please refer to P12 for operating instructions and P21 for setting procedures.)

7. How to Use

Tightening operation
Example）Target torque: 100N ・ m
 Target range ：5%
Blue LED turns on to indicate the target torque.
Start tightening
When it reaches 20% of the target torque, red LED
turns on. (Red LED may turn on at 7.5% of the max
capacity torque in case 20% of the target torque is
higher than this value.)
As torque increases, the red LED moves toward right.
When it reaches 80% of the target torque value, buzzer
starts to sound off-and-on (slow pace) to indicate the
target torque is near.
When it reaches the target torque range, the blue LED
starts to blink and the buzzer goes off continuously to
inform tightening completion.
If it exceeds the target range, the red LED turns on
again, and the buzzer pattern turns to off-and-on (fast
pace).
Press MEM key to save and proceed to the next
counter. If you need to clear the data, press C key.
※ It does not give a judgement.
Example）Target torque: 0 N ・ m
Blue LED at the target torque part will NOT turn on.
When it reaches 7.5% of the maximum torque capacity,
the blue LED turns on and starts to move toward right.

② Judgement tightening mode "JUDGE"
This mode is for tightening with a judgement function.
Set the tightening mode to "JUDGE".
Set the target torque range (lower limit value and the upper limit value) and tightening direction. A judgement will be given
as you press MEM key after tightening (In Auto memory/reset mode, the judgement will be given automatically).
If you apply torque in the opposite direction against the settings, Peak Hold function will be ineffective.
(Please refer to P21 for setting procedures.)
Selecting the target torque
PEAK mode (set the memory counter to 01 – 50).
Push MD key to proceed to torque setting.
Use ▲▼ key to select pre-registered torque value and press MEM key to conrm.
When there is measured data remained in the memory, you cannot change torque setting. Please clear the measured
data before change.
Press MD key or C key to proceed to measuring mode without changing the torque setting.

Example) Inspection by re-tightening method.
Retighten the already tightened bolt. （LED will not turn
on at no loading condition.)
When it reaches 7.5% of the maximum torque capacity,
the blue LED turns on.
As torque increases, the blue LED moves toward right.
Stop tightening as the bolt starts to rotate again, and it
reads out the torque value at that moment.
Press MEM key to save the data.
(If the set torque is Zero values, Auto memory/Reset is
not effective.)
Press C key to clear the data.
Cautions)
In case you accidentally apply over 105% of the max
capacity torque.
The applied torque value and "----" appears on LCD
alternately while the red LED blinks and the buzzer
goes off.
In this situation, data saving is not possible by pushing

Insert AA batteries (2pc) inside the handle of the main body.
Please be careful not to place them at wrong polarity (see below illustration).
Both nickel-hydrogen battery and alkaline battery can be used.
However, nickel-hydrogen battery is more recommendable (See below ※).
Please refrain from using a new and old battery together, or different type of batteries at the same time in order to
maintain stable performance.
※Nickel-hydrogen battery and alkaline battery have different nal voltage.
CPT indicates battery shortage by showing "LOBATT" based on rechargeable nickel-hydrogen battery voltage.
Therefore, when using alkaline batteries, it may show the "LOBATT" display before using up the batteries.
