KMK 7

Digitized AC and DC fault locating bridge, menu controlled, automatically balancing and with integrated functions for acceptance tests and screening tests.

• Automatically balanced bridge
• For maintenance and series tests
• Fault location measurements as per: Murray, Küpfmüller and Graf (Fischer)
• Measurement is possible even with residual voltages on test object of up to 40 V AC or DC
• Measurements possible on loaded and unloaded cables
• Input of cable temperature via test sonde RS 232 interface for printer or PC
• Easy menu-driven operation
• Main functions by fix defined keys
• Storage of test results
• Power supply by NC-accumulator, external 12 VDC or main supply
• In-built charger, operation time 6-8 hours
• Splash-proof with cover open, waterproof with cover closed

Fault locating methods:

• Murray with one healthy wire of the same kind (2-wire)
• Graf  with any two healthy wires (3-wire)
• 4-wire measurement in case of low-resistive loops
• Küpfmüller in case of a poor healthy wire (i.e. manual switching at the far end)

Optional extra:

• Remote circuit closer
