Prescience Calibration
ISO 17025 Accredited
By offering calibration service for DC Nutrunner, torque transducers, angle encoder, transducer power tools, and rotating torque tools, optical level, theodolite, total station, point laser, line laser, rotation laser, Prescience Calibration has earned a unique position by complying to NABL Standards for getting accredited for calibration of DC Nutrunner for the first time in India among calibration laboratories. The laboratory is in all compliance to ISO IEC 17025 (NABL Accreditation), the calibration laboratory quality standard. This implies a high level of technical competence and well documented, traceable calibrations. It is thus assured that the calibration services offered are in compliance with ISO 9000 and ISO/TS 16949 and any other standard as applicable. Laboratory backed up by Technical expertise over decade in Calibration of Nutrunner also offers on-site calibration service
BIPM Definition
The formal definition of calibration by the International Bureau of Weights and Measures (BIPM) is the
following: "Operation that, under specified conditions, in a first step, establishes a relation
between the quantity values with measurement uncertainties provided by measurement standards and
corresponding indications with associated measurement uncertainties (of the calibrated instrument or
secondary standard) and, in a second step, uses this information to establish a relation for obtaining
a measurement result from an indication."

DC Nutrunner Calibration
Transducerized tools (DC Nutrunner or any torque tool) must be tested regularly in order to establish continued trueness of the delivered torque. Thus, it must be checked that the tool controller reading agrees with the reading of a torque reference transducer. This operation is often called tool calibration. It is based on a certain number of readings, generally at least 25. The average discrepancy between the tool and the reference must lie within tolerance. If not, an adjustment must be made
When a transducerized power tool (DC Nutrunner and other torque tools) is used, it is connected to a controller which runs and monitors the torque tool. The controller is part of a torque and angle measuring system and must be calibrated to maintain accurate torque tool operation. The controller must be calibrated both on a regular basis and following a service, when parts which may influence the torque measurement have been exchanged.
Rotary Torque Tool
All tools are subject to mechanical stress, e.g., gears, bearings and motors
are subject to wear. As a result, a tool may not deliver its expected torque or may not be as
accurate as expected. The consequences are obvious. Nuts and screws may not be tightened to the
prescribed torque, joints may fail and some may even cause injuries. To avoid this, tools need
regular calibration
Shut off type torque tools either battery operated torque tool or pneumatic torque tool need calibration at regular intervals.Prescience calibration specializes in calibration of battery operated torque tool and air operated torque tool in accordance with VDI 2645 standard. We provide the tool capability value along with calibration certificate.
