    DiLOG testers....any good? And is 440v overvoltage rating adequate?

    I'm looking at new testing equipment and quite like the look of the dilog's. They seem to do what every other tester does but they are cheaper and the customer service has rave reviews. I noticed they all only go up to 440v overvoltage whereas the higher end Flukes etc go to 550v. Any ideas?

    Power Rating

    Got a pic off a customer of a machine data plate. Bit odd with the two ratings and the other with the + signs in. Can anyone help? Is it startup and running current or something else? Am I also right in thinking the 1 st pic machine is going to pull about 47 Amp per phase? Thanks in advance
