ZERO/TARE FOR WRENCHES MANUFACTURED PRIOR TO 11/1/2016
If the wrench/tester serial number has a " * " symbol laser marked as part of the serial number it was
manufactured after 11/1/2016 and can be zeroed/tared as described in this manual. Wrenches without
the " * " symbol in the serial number are manufactured prior to 11/1/2016 and require that the wrench be
turned off first and then on to zero/tare the display (for example when going from the clockwise (CW) to
counter-clockwise (CCW) direction).
INFORMATION
JETCO TORQUE TOOLS RECOMMENDED CALIBRATION INTERVAL
JETCO recommends calibration at 6 months to 1 year intervals, however, actual intervals are user
dependent and can vary based on cycles, environment, tool use, criticality of the application and other
factors. It is the user's responsibility to determine the best calibration interval for their torque tools.
The following is a list of tool accuracies by series. JETCO accuracies are based on Indicated Value which
means that the tool is guaranteed to meet or exceed this accuracy level at the reading within the given
range.
Dial Wrenches: +/- 4% (both directions) from 20-100% of range.
Electronic Dial Wrenches (ED series): +/- 1% (both directions) from 10-100% of range.
SuperDuty/Revo Electronic Wrenches: +/- 2% (both directions) from 10-100% of range.
TED series Torque Testers: +/-1% (both directions) from 10-100% of range.
TTS-2000 Torque Meter when used with:
In-Line transducers: +/- .5% (both directions) from 10-100% of range.
Bench Mount Transducers: +/- .25% (both directions) from 10-100% of range.
Pre-set click wrenches: +/- 4% Clockwise and +/- 6% counterclockwise.
Micrometer click wrenches: +/- 4% Clockwise and +/- 6% counterclockwise.
