| Operating Principle: | Ultrasonic, pulse-echo measurement method |
| Thickness Measuring Range: | 0.025 inch to approximately 12.00 inches; 0.50 mm to approximately 300.0 mm; depending on probe selection and material under test. |
| Material Velocity Range: | 39,400 to 393,662 in/s; 1000 to 9999 m/s |
| Displayed Resolution: | Four options, selectable via the keypad:
1.) 0.001 inch from 0.025 to 9.999 inches. Over range indicator when greater than 9.999 inches.
2.) 0.01 inch over entire range.
3.) 0.01 mm from 0.60 to 99.99 mm. Not available in HI SPD mode. Over range indicator when greater than 99.99 mm
4.) 0.1 mm over entire range |
| Reading Stability: | Nominal measured value ±0.001 inch (0.025mm) over the temperature range of the instrument. |
| V-Path Error Correction: | Automatic, microprocessor controlled |
| Linearity with KBA560 Probe: | ±0.002 inch (±0.05 mm) when calibration point is ≤1.0 inch (25 mm); ±0.004 inch (±0.1 mm) when calibration point is >1.0 inch (25 mm). |
| Probe Zero Adjustment: | Push-button, keyed to built-in probe zero block |
| T-minimum Set Range: | OFF or 0.020 inch to 9.999 inches; 0.5 mm to 300.0 mm. |
| Calibration: | One point, off block, with known thickness calibration standard of same material and velocity as material to be measured; probe zero required. |
| Display Update Rate: | 4 Hz in 0.001 inch, 0.01 inch, and 0.1 mm resolution modes; 3 Hz in 0.01 mm resolution mode. |
| Measurement Rate: | 4 Hz in 0.001 inch, 0.01 inch, and 0.1 mm resolution modes; 3 Hz in 0.01 mm resolution mode; 16 Hz in High Speed Minimum Capture (HI SPD) mode. |
| Reciever Gain Level: | Three options, selectable via the keypad:
Automatic: High gain will be enabled for material velocities up to 246,000 in.s (6,248 m/s). Low gain will be enabled for velocities over 246,000 in/s.
Manual Low: Low gain will be enabled over the entire velocity range.
Manual High: High gain will be enabled over the entire velocity range. |
| Data Logger Capacity: | 1200 Readings maximum; 999 readings if number of files is set to 1; readings are stored sequentially |
| Number of Data Files: | 1 to 99; memory is divided by number of files, i.e. one file of 999 readings, two files of 600 readings each... 99 files of 12 readings each. |
| Serial Protocol: | 1200 baud; 8 data bits; 1 stop bit; no parity |
| Data Transfer: | Via SEND key or optional remote SEND Switch |
| Memory Retention: | Typically 10 years |
