Sew 1824 LP

Category: Loop Testers
FEATURES
● Microprocessor-controlled.
● Measures Earth Resistance without the need for poles 
   in the ground or external measuring wires.
● Earth measurement uses the real earth current path
   and the current generated by the electric network,
   without the need for any disconnection.
● The Earth Resistance displayed is exactly the earth
   resistance that the earth current will need to go
   through if an earth fault occurs.
   (you do not need to add all the bonding points and 
   connection paths)
● Displays voltage supply at the transformer(Line to
   Neutral), without loading the transformer.
● Single one smart push button operation; ON, Scroll
   through results and menus.
● Checks wiring integrity (LEDs).
● Auto-off / Auto-ranging (software range).
● Color-coded test leads.
● Combined prospective short circuit current, loop, and
   earth tester.
● Loop test for L-E and PSC between L-N.
● Voltage test L-N.
● Display can be customized for large orders.
