## Description

PRODUCT BENEFITS Great value for money, great specification in a hand held style of case Auto RCD test and Ramp test makes your job easier The KTD50 is a comprehensive RCD tester that tests type AC and ACS RCDs from 30mA to 500mA. Special RCD features include an auto, ramp and x 2 I ΔN test. In the auto-test mode the instrument automatically runs through all the six standard tests whilst the operator only has to stand by the RCD and reset it every time it trips. All the result can be viewed using the recall button. The ramp test slowly increases the tripping current until the RCD trips. The display is in mA. It will show up RCDs that are out of specification and those that will be susceptible to nuisance tripping. It can also be used to indicate which circuits have high leakage currents. The x 2 I ΔN test satisfies the advisory note for verification of disconnection times as in the 17th Edition regulation 411.3.2.2. The Ketch KTD50 also measures main voltage and incorporates a full socket tester that checks for any miss-wiring at the socket. Last but not least this tester has the unique feature of a mains polarity test. It will check that the mains incoming supply is not in the very hazardous condition of line/neutral reversal. PRODUCT FEATURES Comprehensive RCD tester Includes RCD ramp and auto-test Full socket tester functionality built in Unique mains supply polarity test (checks that line and neutral are not switched at the supply) Measures mains voltage Special x 2 I ΔN RCD function Tests selective RCDs INCLUDES KAMP13 - Mains Test lead only Certificate of Conformity

Review: Good product but the display protective label was very hard ... - Good product but the display protective label was very hard to peel off and left a tough glue smear which I had to clean with label remover. As a result the display was slightly matted. The type of test (X11, x5, etc) characters are too small and hard to read. The beep volume is also too low and hard to hear in a noisy environment.
