The instrument can be used on any cable consisting of at least two separate conductive elements, one of which may be the armouring or
screen of the cable. It has internal matching networks to allow testing of 25 Ω, 50 Ω, 75 Ω and 100 Ω cables. (These typically correspond to
power, coaxial data and data/telecoms cable). By selecting the TDR impedance closest to that of the cable under test, maximum power can
be transmitted into the cable allowing long cables to be tested. If the impedance of the cable under test is unknown, the auto-impedance
function may be used to determine the cable impedance and set-up the TDR automatically.
The distance units can be changed between metres and feet. Display contrast is automatically adjusted for temperature, but can be adjusted
further for optimum display. A backlight aids viewing in low ambient light conditions.
The instrument can be powered by manganese alkali, or nickel-metal-hydride battery. All cells must be of the same type.
