Maximum Length: 8,000 feet (2,438 meters) on certain cable types, 4,000 feet (1,220 meters) on most cable types, and 500 feet (152 meters) on cables with high loss. The tester shows -Err if the cable is too long to be correctly measured.
Representative Maximum Cable Length:
8,000 feet (2,438 meters): CAT-3 Twisted Pair
8,000 feet (2,438 meters): CAT-5 Twisted Pair
6,000 feet (1,830 meters): 12/2 AC Wire
3,000 feet (900 meters): RG-6/U TV Coax
1,500 feet (457 meters): RG-174/U Coax
Minimum Length: No minimum length (can read a bridge tap at 0 feet/meters). Minimum non-zero reading is 2 feet or 1 meter.
Length Accuracy:
"±2 feet (±0.6 m) for cables less than 10 feet (3 m)
±5 feet (±2 m) for cables longer than 10 feet (3 m) and shorter than 200 feet (60 m)
+/-3%+/-5 feet (±2 m) for cables longer than 200 feet (60 m)"
Distance to Bridge Tap: 0 feet to 3,200 feet (975 meters)
Minimum Length of Bridge Tap: 10% of the distance to the bridge tap. Dependent on the cable characteristics.
Measurement Rate: Maximum of 4 complete measurements per second, decreasing to 2 seconds per measurement based on cable size and uniformity.
VOP: Adjustable from 20 to 99, saved in flash memory.
Test Technology: Time Domain Reflectometry (TDR) with 100 Ω drive impedance, 6v maximum pulse height.
Cable Type: Virtually all two or more conductor cables.
Power: 4 AA alkaline batteries.
Reverse Battery Protection: No damage to the tester will occur if the batteries are installed backwards.
Battery Life: 35 hours (typical)
Low Battery Indication: LED display alternates between LO and bAtt when the battery voltage falls below 4.5v.
Maximum Output Voltage: 4 voltage peak
Maximum Isolation Voltage: 250 volts RMS
Voltage Measurements:
Range: 0 volts AC to 115 volts AC; 0 volts DC to ±150 volts DC
Accuracy: AC: +/-1%+/-2 volts (45 Hz to 65 Hz); DC: +/-1%+/-2 volts DC
High Voltage Detection: AC voltage detected to 115 volts; DC voltage detected to ±150 volts.
AC voltage ≥90 volts or DC voltage ≥100 volts causes high voltage warnings to show on the display
SmartTone® (5-tones) Range: 7,000 feet (2,134 meters)
Toner Range: 52,800 feet (16,093 meters)
Tone Injection: Approximately 1 kHz at an amplitude of 80% of battery voltage. Variable frequency and cadence. Tone characteristics change as cable condition changes to “normal-open” from any other condition.
Impedance Range: 35 Ω to 330 Ω with auto-compensation within this range. Cables with impedances outside this range will not be properly tested and may produce erratic or incorrect readings.
Temperature Range: Operating: 32°F to 104°F (0°C to 40°C)
Storage: 32°F to 131°F (0°C to 55°C)
Humidity: Operating: 20% to 80% relative humidity
Storage: 0% to 100% relative humidity
Operating Humidity: 80% maximum at 86°F (30°C )
50% maximum at 104°F (40°C )
Operating Altitude: 9,843 ft max (3,000 m max)
Weight: 1 lb (454 grams)
Dimensions: 7.4 in x 2.7 in x 1.4 in (18.8 cm x 6.9 cm x 3.6 cm)
