Eddy Current Specifications (All NORTEC Models) |
Probe types |
Absolute and differential in either bridge or reflection configuration. The instrument is fully compatible with NORTEC POWERLINK probes, as well as other main probe and accessory suppliers. |
Probe connectors |
16-pin LEMO and BNC featuring internal automatic balancing for BNC connector (absolute probes). |
Frequency range |
10 Hz to 12 MHz |
Gain |
0 dB to 100 dB in 0.1 or 1 dB increments |
Rotation |
0° to 359.9° in 0.1° or 1° increments. |
Sweep |
Variable from 0.005 s to 10 s per division (total of 13.3 divisions with FINE grid). |
Filters |
Low-pass: 10 Hz to 2000 Hz and wide band. Highpass: off or 2 Hz to 1000 Hz, user-selectable in constant “figure 6” or “figure 8” filter type. Continuous null (low-frequency HP filter): 0.2 Hz, 0.5 Hz, 1.0 Hz. |
Probe drive |
LOW, MEDIUM, and HIGH (2 V, 5 V, 8 V) |
Display erase, persistence |
Display erase (0.1 s to 60 s), persistence (0.1 s to 10 s) |
Available alarm types |
3 simultaneous alarms. Choices include BOX (rectangle), POLAR (circle), SECTOR (pie), SWEEP (timebased), CONDUCTIVITY, and COATING THICKNESS |
Conductivity (NORTEC 600C, NORTEC 600S, and NORTEC 600D) |
Frequency |
60 kHz or 480 kHz |
Digital conductivity specification |
Digital conductivity display from 0.9% to 110% IACS or 0.5 to 64 MS/m. Accuracy within ±0.5% IACS from 0.9% to 62% IACS and within ±1.0% of values over 62%. Meets or exceeds BAC 5651 specifications. Accuracies dependent on probe frequency, range of calibration, and coating thickness. |
Non-conductive coating thickness |
Nominal accuracy of non-conductive coating thickness of ±0.025 mm (±0.001 in.) from 0 mm to 0.254 mm (0.00 to 0.010 in.) range and ±0.50 mm over 10 mm to 0.5 mm (0.01 to 0.020 in.) range. Accuracy dependent on conductivity range, probe frequency, and range of calibration. |
Scanners (NORTEC 600S and NORTEC 600D) |
Scanner compatibility |
Operates Olympus scanners (MiniMite, Spitfire, RA2000, and PS-5) and other major supplier scanners, from 120 RPM to 3,000 RPM. |
Dual Frequency (NORTEC 600D) |
Frequency adjustment (dual frequency mode) |
Two fully independent frequencies, operating in simultaneous injection |
MIX options |
F1 - F2, F1 + F2, and automatic true mixing |
