The Kewtech KTD40 uses the latest in electronic design to produce a compact and feature packed test instrument. For instance it includes a full socket tester that will check for any mis-wiring at the socket. It will also check for the very hazardous condition of a reversal of line/neutral at the supply.
This instrument is capable of measuring true loop impedance, this gives more relevant information when testing PSC/PFC as the reactance of the suppliers transformer measured as well as the pure loop resistance.
With the optional distribution loop test a high current two wire test can be carried out. A high or low current (non trip) test is conducted and after the reading is displayed the PFC or PSC can be shown instantly on the press of a second button.
See pdf file for full specifications.

Features

Low current non trip and high current loop impedance (Patented)
High current test reads true loop impedance (including the supply transformers reactance)
Full socket tester functionality built in
Unique mains supply polarity test (checks that line and neutral are not switched at the supply
Instant readout of PFC/PSC by use of secondary button
Voltage test function L-N, L-E & N-E
Fully protected against accidental to phase to phase protection

The Kewtech KTD50 is a comprehensive RCD tester that tests type AC and ACS RCDs from 30mA to 500mA (see specifications pdf). 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 results can be viewed using the recall button.

The ramp test slowly increases 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 Kewtech KTD50 also measures mains voltage and incorporates a full socket tester that checks for 18 socket wiring conditions. 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/phase reversal.
