Measuring

Range:

From 1 to 96 inches (25.4 to 244 cm).

Quantities: Time - Nanoseconds.

Elongation - Change in length (inches/mil- limeters).

Load - Force load applied (pounds KIP or megapascals MPa).

Stress - Force for unit area stress applied (inches per inch or millimeters per millime- ter).

%Strain - Ratio of elongation to effective length.

Resolution:

+/- 0.00001 inch (0.0001 mm).

Velocity Range: 0.0492 to .3937 inches/microsecond (in/μs)

(1250 to 9,999 meters/sec).

Fixed, Single, and Two-point zero calibra- tion options.

Select bolt material types from a preset or custom list.

Units:

English & Metric / Farenheit & Centigrade.

Display

A-Scan: Rectified +/- (half wave view), or RF (full waveform view).

Large Digits: Display and toggle between nanoseconds, elongation, load, stress, and strain; Digit Height: 0.400 inch (10mm).

Limits Bar (alarm limits): Set Hi & Lo alarm limits for displaying an acceptable toler- ance range.

Repeatability Bar Graph: Bar graph indi- cates stability of measurement.

Data Logger:

Total of 8,000 bolts in multiple bolt groups. Stores both waveform views, nanoseconds, elongation, load, stress, strain and all gauge settings for each reading.

Memory:16 megabit non-volatile ram.

Transducer

Transducer types:

Single element (1 MHz to 10 MHz & 1/8 to 1inch diameters). Magnetic & Non-Magnet- ic options.

Glue-on transducers available for short bolts with minimal elongations to eliminate transducer placement errors.

Locking quick disconnect “00” LEMOconnectors. Standard 10 foot cable.

Custom transducers available for special applications.

Temperature probe for automatic temperature compensation.

Auto Set:

Locates the detection signal, optimizes the gain setting, and adjusts the overall display to show the waveform and detec- tion point automatically.

Field Calibration:

Vector & linear regression.

Certification

Factory calibration traceable to NIST & MIL- STD-45662A.
