Multi-wire Cable: Connect the clips to any two wires.
4.1 Testing a Cable
Having followed the set-up procedures in the preceding sections, a
typical display showing impedance anomalies is shown below.
Further examples are shown in section 4.6.
The vertical cursor line is moved left or right along the line of the
trace by pressing ◄ and ►buttons to determine the distance to
the event. Position the cursor at the beginning of the event and
read off the distance at the bottom left corner.
On the fault display shown above, an Open cable has a splice at 30
feet. To increase the gain of the return see section 4.4. The open
end of the cable is shown as a large positive spike. This is used to
determine the end of the cable run and the overall length of the
cable.
4.2 Selecting Range Scales
The Pro400 has 11 range scales covering the range of 23 to 19,000
feet.
To select a range scale, or scan the cable run, press and hold down
the Range button and press ◄ to decrease range or ► to increase
range.
