TORQUE MEASUREMENT

Calibration details
TORQUE TOOL TESTER (TTT)

The Torque Tool Tester (TTT) shares all of the extensive features of
the Torque Screwdriver Tester (TST) except that it has no internal
transducer. Instead, the TTT offers not one but three external
transducer interfaces allowing any three transducers to be
simultaneously connected. Selection between the transducers
is made by a rotary switch at the back of the instrument case�
The TTT is supplied as standard with a UKAS accredited
calibration certificate in CW direction.
Any transducer from Norbar’s Smart range and most mV/V
calibrated transducers from Norbar or other manufacturers can
be connected to the TTT. The Smart feature means that once a
transducer has been connected, the instrument will automatically
recognise calibration details such as mV/V output, serial number and
capacity�
• Instrument accuracy of ±0.05% (±0.1% when below 10% of transducer
capacity)
• System accuracy with a typical Norbar transducer, ±0.5% from 20% of
transducer capacity
• Pictorial display panel for easy mode selection
• Limit detection with low, pass and fail indication. Up to 12 target values can be set
• Digital limit state output for control of external tools
• Operation from fast charge internal battery pack (maximum time of 3 hours 20 minutes for full charge) or a.c. supply (90 to 264 Volts)
• RS-232-C serial data interface for connection to a printer or PC. Continuous RS-232 output when used in Track mode (up to 11 readings per second)
• Pulse count feature in Impulse mode and Clutch Tool mode
• Smart intelligence for transducer recognition, now displays transducer capacity, units and Serial Number
• Memory for calibration details of 20 non -Smart mV/V calibrated transducers
• Analogue output allows the instrument to be used as part of a process control system for performance analysis
• User-selectable frequency response for each mode of operation
• All user-selectable features have password protection. The instrument can be issued to users with only the required modes of operation and units of
measure enabled. This feature can virtually eliminate operator induced errors
• Peak memory modes can now be configured to have auto reset (previously only manual reset was possible)
• Series 3 users can set up their own measurement units, making it possible to interface with non-torque transducers, for example load or pressure
