Technical Specifi ca on
The TX8000 is 6Km range Time Domain Refl ectometer housed in
a rugged over moulded case being water proof to IP67 and drop
resistant, designed for outside use, but suffi ciently small and light
weight for widespread use. Using a 3.5-inch QCGA colour display
informa on is clearly displayed; an illuminated key pad makes the
TX8000 ideal for use in poorly lit areas.
Using 11 range scales with a fi rst range of 7 meters near end
faults are clearly visible. Using the scan hold facility faults may be
retained on screen for closer examina on or when in scan mode
intermi ent faults may be easily iden fi ed. The user variable gain
control allows small events on the waveform to be magnifi ed for
clearer iden fi ca on. With dual cursors each cursor giving its
length measurement and a diff eren al distance between cursors
the length of a fault may be iden fi ed. To assist in the iden fi ca-
 on of faults a number of known fault types may be super im-
posed over the displayed fault for easier iden fi ca on
