Proven multifunction tester combining the latest anti-trip technology, phase rotation, earth resistance & advanced memory, with easy to use functionality. Specifically designed for the UK market.
The KT65DL incorporates Anti Trip Technology (ATT) which electronically bypasses RCDs when performing loop impedance tests. This saves time and money by not having to take the RCD out of the circuit during testing and is a safer procedure to follow.
With the ATT function enabled, a test of 15mA or less is applied between line & earth. It enables loop impedance measurements without tripping RCDs rated at 30mA and above.
FEATURES
Easy to use
Phase rotation in line with new 17th edition requirements.
Advanced memory with free software.
NEW Anti-Trip Technology for full no trip LOOP testing on all RCD types.
Test button in probe as well as lockdown test button for ‘hands free’ testing.
Easy PFC & PSC measurement without the need to alter test probes.
250, 500 & 1000V insulation tests with auto discharge.
Additional LED for warning of high voltage output in insulation test mode.
Memory for test lead resistance compensation.
Backlit display.
Auto-test memory for RCD testing with all results shown on one screen.
Conducts phase to phase loop tests.
Earth resistance for earth rods (with optional Earth Spikes).
End of line calibration certificate included.
Can be used with rechargeable batteries.
Complies with BS7671 (Part P).
