○Inspection report list
This indicates the results of accuracy and performance
inspection of the product conducted before shipment based
on our internal standards.
○Calibration and adjustment
The torque accuracy check (calibration) and adjustment
services are available for a fee.
○Issuance of "calibration certificate"
The calibration certificate certifies that the value indicated by the
measuring instrument is calibrated by using inspection
equipment in conformity to the standard equipment traced
against the international standards. It independently and officially
certifies the accuracy and performance of the measuring
instrument.
Contents of the calibration certificate are as follows:
a. Inspection report
b. Inspection date
c. Declaration of tracing against the international standards
d. Identification of the calibrated article (management number,
item name, model number, manufacturer and manufacturing
number)
e. Item name, model, equipment capacity of the inspection
equipment used for the calibration, and last and next
calibration dates of the inspection equipment
* The inspection report indicates results of accuracy inspection
based on KTC's standards conducted at the time of shipment,
while the calibration certificate provides information of b.
through e. above besides the inspection report.
For other inquiries about repair, etc., please contact the distributor.

Features and applicationsof the product
Packed contents
○Features
• The driver type digital ratchet is a preset type driver with
excellent workability combined with digital functions for
accurate indication.
• The torque value is indicated by light and sound.
• Full-scale torque measurement functions that satisfies
the international standard (ISO).
• Torque in both right and left directions can be measured.
• Up to 5 target torque values (preset values) can be
registered.
• Various settings can be customized to use indications
and alarm sound (ON/OFF) according to your needs.
• In the Auto Clear mode, indications are cleared after a
certain time has passed even during continuous works.
It is not needed to press the clear button each time.
• In the Pass/Fail mode that sets the upper and lower limits
of tightening torque, the number of passes can be
counted.
• In the Track mode, the real-time torque value is indicated.
When the load is eliminated, the indication becomes "0".
○Applications
• Measurement of tightening and loosening torque values
of right-hand and left-hand screws.
• Tightening work to the specified torque.

Starting up
Keep the main unit free from any force until "0 (zero)" value is
displayed on the display after turning the power ON. Turning the
power ON under any force may cause wrong torque indication.
After turning the power ON, make a torque measurement with the
ambient temperature stable. In places where the temperature
varies sharply, turn the power ON/OFF frequently.
Press the button gently.
If any error code is displayed,
refer to P. 25.
