LOOP/PFC/PSC Testers

• Anti-Trip Technology for complete trip free Loop testing on all RCDs rated 30mA and above.
• Dual Display allows simultaneous measurements like Loop & PFC/PSC.
• Two wire connection for Loop L-L, L-N and PSC testing is possible.
• Phase rotation, Voltage and Frequency measurements.
• Lock-down test button for ‘hands free’ testing with auto-start operation.
• Display and front panel keyboards with Backlight to be visible in dark places.
• Water and Dust proof (IP54)
