Warning

Operators should wear protection such as a mask and gloves in case pieces or components break away from the unit under test. Whether the unit is ON or OFF, DO NOT exceed the capacity of the sensor. NEVER exceed 120% of the rated capacity, or the torque sensor will be damaged. At 110% of the rated capacity the display will flash a warning. Measure in line torque only. DO NOT attempt to measure forces at an angle to the sensor – damage to sensor may result. Do not attempt to repair or alter this instrument. Warranty will be voided and damage to the unit may result. Use and store within the stated temperature and humidity ranges, or damage and failure may result. Ensure during testing unit is properly mounted & secured to stable sur- face. Mount display with the two integral 8.5 mm mounting holes only. If not using this instrument for extended periods of time, remove the batteries to prevent potential battery leakage from causing product damage.

The TNC Digital Torque Cap Tester is a simple operation test in- strument for quickly measuring Open and Close torque values up to 14.8 ft-lbs (20 N-m). The TNC meter is used in medical, pharmaceutical, industrial quality control, R&D and countless oth- er torque applications.

The TNC’s provide long operation life and power flexibility with the ability to work from the internal rechargeable battery or included AC adapter.

The TNC’s have six modes of operation: Track for live readings, Peak which records the highest level over a test, First Peak which records a reading after a programmed decrease, Auto Peak which resets after a period of time, Auto First Peak which resets the first peak after a period of time, Double Peak which provides two separate peak readings from programmed decreas- es. Preset operation with programmable tolerance thresholds for quick pass fail test is available in all modes.

The analog bar graph on the backlit, reversible LCD aids users by providing the resultant torque’s current position compared to the full scale range along with the direction of the force. Pass/fail icons produce live test feedback allowing instant determination of the results.

Every tester comes standard with USB and RS-232 outputs. The TNC’s software enables the uploading of data and the additional statistical analysis with its auto-calculation of the selected values.

These excellent features make the TNC Torque Cap Testers a valuable and versatile addition to the production, R & D and qual- ity control departments.
