Length measurement of twisted pair cable:

Range: 1 ~ 350 m (3 ~ 1000 ft)

Calibration accuracy: 3% (±0.5 m or ±1.5 ft) (calibrating cable > 10 m)

Factory accuracy: 5% (±0.5 m or ±1.5 ft) (AMP, AT&T Class 5 cable)

Display unit: m or ft

Length calibration:

User can set calibration coefficients manually using a cable of known length.

The calibration cable length must be more than 10 m.

Wire sequence and cable fault locating:

Detects open circuit, short circuit, reverse connection, and cross-over.

Automatic time-delay shut-off:
