WARNINGS & CAUTIONS
CAUTION!
To avoid serious malfunction of equipment, never open the front panel directly with
bare hands so that ESD is ruled out. Refer to our company’s safety procedures when
working with electronic equipment & systems.
WARNING!
Use only the specified AC adapter. Use of another type of AC adapter can damage
the instrument and create the danger of fire and electrical shock.
WARNING!
To avoid the danger of fire and electrical shock:
Never use a voltage that is different from that for which the AC adapter is
rated.
Do not plug the unit into a power outlet that is shared by other devices.
Never modify the power cord or excessively bend, twist, or pull it.
Do not allow the power cord to become damaged. Do not place heavy
objects on the power cord or expose it to heat.
Never touch the AC adapter while your hands are wet.
Should the power cord become seriously damaged (internal wiring
exposed or shorted), contact the manufacturer to request servicing.

Nominal V/2 values for different types of Cables
S.No Cable Type Nominal V/2 Variation in V/2
1 Jelly 90 88 to 95
2 Paper 102 102 to 110
3 Co-axial 123 122 to 130
4 PVC 72 70 to 74
Note:
1) Nominal value of V/2 for same type of cable varies depending on the gauge of
the conductor and the insulation material.
2) For better results V/2 value of cable under test should be determined using a
pair of known length in the same cable.
3) Preset value of V/2 can be changed either through “Others” in “Setting” mode or
directly in Pulse Echo Model to display preset value in “Cable Type” box & then
changing it using 67 arrow keys
4) V/2 value of 0.9mm drop wire is 69 ± 1 & V/2 value of 1.5mm PVC power cable
is 74 ± 1

Leading Particulars & General Data:
ELECTRONIC Cable Fault Locator is basically a High Resistance Fault Locator to mainly
locate Low Insulation & Contact faults in UG Cables. Its simple design, ease of
operation, very light in weight makes it an ideal tool for even an inexperienced
person to locate the faults. This instrument can also be used to measure distance
to fault in case of clear open faults using pulse reflection principle.

Introduction:
Electronic Cable Fault Locator Model 5379 works on a proven pulse reflection
technique in combination with a Bridge network to detect most common faults
quickly. It transmits a pulse of controlled width and amplitude along the cable. The
velocity of propagation will majorly depend upon the dielectric surrounding the
conductor. Whenever there is a change of dielectric constant due to fault the pulse
is partially or wholly reflected back & both incident & reflected pulse are displayed
on a 240 x 1218 pixels LCD Display. The time between the incident and reflected
pulse is directly proportional to the distance.
The distance to fault is computed internally and displayed on the 5” Graphic LCD
display in METERS directly.
Purpose To locate the Open , Short & Low Insulation type of faults in
a cable with direct read out of the fault distance in meters
