CABLE FAULT LOCATOR ECFL 30

WHERE IS THE FAULT ? ECFL30 GIVES THE ANSWER !

FOUR INSTRUMENTS IN ONE

• Active Bridge for accurate location of
faults where the level of disturbing
voltages are low
• Passive Wheatstone Bridge for loca-
tion of faults where the level of dis-
turbing voltages are high
• Graaf Fault Locator for accurate fault
location on totally water-soaked cable
where the disturbing voltages are
usually high and intermittent
• TDR to find low impedance faults and
splits causing cross talk between the
pairs. Manual and Automatic configu-
ration provided

APPLICATIONS AND FEATURES

The CABLE FAULT LOCATOR ECFL 30 hand-held in- Extremely Simple Operation
