This two wire earth loop tester has a 40 KA PFC range, 0.001 Ω resolution and an R1 and R2 display. It is the highest specification tester in the LTW300 range and has an auto start function so that testing begins as soon as the leads are connected.
The LTW425 is designed so that it doesn’t trip 30 mA RCDs and can be used on a wide range of voltages. It can be used for phase to phase, phase to earth and phase to neutral testing.
Features of the LTW425:
· Two-wire non-tripping tester
· Can be used for 110v to 280v and 50v to 440v applications
· 110v centre-tap to earth (55v phase to earth) loop testing
· Auto noise detection feature
· Auto start feature
· Measures voltage and frequency
· 20KA PFC (Prospective Fault Current) range
· Max Zs display
· R1+R2 display
· CAT IV installation testing
