APPENDIX A: Technical Specifications

A.22 Length

Range: 0 to maximum distance, where max. distance = 457 m (1500 ft.) for twisted pair cable

Accuracy: + K + Length resolution + NVP uncertainly, where K = ±4% of length or 0.6 m (2 ft.), whichever is greater.

Length resolution: 0.3 m (1 ft.)

A.23 Resistance

• Range: 0 to 500 Ω

• Accuracy: ±0.5 Ω @ 0 to 15 Ω ; ±2% @ 15 to 500 Ω

• Resolution: 0.1 Ω
