Megger TDR900

 MGR-TDR900/DS Hand-Held Digital TDR

The TDR900 can be used for any cable consisting of at least two insulated
metallic elements, one of which may be the sheath or shield of the cable. The
Meter has automatic internal matching networks to allow testing of 25O, 50O,
75O, 100O, 125O, or 150O cables. (These correspond to power, telephony, CATV,
and LAN cables.)

The measurement range spans from 15 feet (5 m) to 10,000 feet (3 km) with a
minimum resolution of 20 inches (50 cm).

Features:
Full autoranging for measuring the length of power, telephony, CATV and LAN
cables, provides distance to an open or short.
Extra large, high resolution backlit LCD.
Automatic output impedance control of 25, 50, 75, 100, 125 or 150 ohms.
User-friendly menu on screen operation.
Cable length calibration function.
Internal library of 39 standard cable types.
CE-Certificated
Accurate to 20 inches (50 cm) throughout the entire range

SPECIFICATIONS:
Except where otherwise stated, this specification applies at an ambient
temperature of 68 F (20 C).

CABLE LENGTH MEASUREMENTS
Range: Depends upon the V.O.P of the cables under test.
12,000 ft (3.7 km)@ V. O. P 99.9
9,800 ft (3.0 km)@ V. O. P 80.0
8,000 ft (2.4 km)@ V. O. P 66.0
6,200 ft (1.9 km)@ V. O. P 50.0

Accuracy*
2 % of reading + 20 inch (50 < 300 ft (100 m)
2 % of reading > 300 ft (100 m)
*This accuracy is effective for Coaxial Cables up to 8,000 feet,
Telephony Cables up to 6,000 feet, and Structured Wiring up to 3,000 ft.
Resolution: 20 inches (50 cm)
V.O.P (Velocity of Propagation): Adjustable from 1.0 % to 99.9 (in 0.1 % step)

CABLE LENGTH CALIBRATION FUNCTION
Allows you to measure the V.O.P, given as a percentage of the speed of light,
of a known cable length.
