Eliminates the transmission pulse ‘dead zone’
10m to 3Km Measurement Ranges
25Ω, 50Ω, 75Ω and 100Ω Cable Matching
Suitable for many cables
Large high resolution backlit display
Internal Matching Networks
IP54 rating
The TDR1000 is an advanced instrument capable of identifying a wide range of cable faults using a technique called Time Domain Reflectometry (TDR).
It offers exceptional features and a range capability normally associated with bigger, more expensive instruments.
The measurement range spans between 10m and 3km (30Ft to 9,000Ft), with a minimum resolution of 0.1m (4 inches).
The TDR1000 can be used on any cable consisting of at least two insulated metallic elements, one of which may be the armouring or screen of the cable.
The TDR1000 has internal matching networks to allow testing of 25Ω, 50Ω, 75Ω and 100Ω cables.
(These correspond to power, coaxial data and data/telecoms cable).
The instrument can be closely matched to the cable using the balance control allowing long lengths of cable to be easily tested and faults close the instrument to be seen.
The propagation velocity value can be similarly adjusted to match the cable, thus ensuring an accurate distance measurement can be directly read.
To enable a wider range of faults to be detected, the gain of the instrument is also variable, allowing more minor faults to be identified over the entire length of the cable.
Other user adjustable settings include changing the distance measurement units between metres and feet and adjusting the propagation velocity units between
a ratio and a distance per microsecond. Display contrast can be set to compensate for all viewing conditions and a backlight assists in low ambient light conditions.
(Except where otherwise stated, this specification applies at an ambient temperature of 20°C.)
General
Ranges:
10 m, 30 m, 100 m, 300 m, 1000 m, 3000 m (30 ft, 100 ft, 300 ft, 1000 ft, 3000 ft, 10000 ft).
