The 1553 will do all the tests; except it won't test the A type Rcd's. Was using a 1552 till about a year ago.I have been offered a very well looked after unit . The price is £160 with all accessories etc . Calibration finished 3 weeks ago. Unit compares reading with another calibrated unit .so a possible good buy ?????
Dont tell me that, the only reason I forked out £800 on a new 1721 was to test type A's, and the 2 wire no trip, oh and not forgetting that it tests rcd's and ZS quicker !I've seen conflicting messages about this. Still have a 1552 as back up, but upgraded to a second hand 1711 to get the A Type test.
15xx series does test "DC type", but noone seems to be definitive about whether that includes Type A - one day when I have both on site I keep meaning to try it out.
the 15xx series doesn't do a 2 wire no trip test, which was worth the upgrade anyway...
At that price and recently calibrated an absolute bargain for sure.
