SEW 1824LP Digital LOOP/ PSC/ EARTH Tester

Loop Testers & Electrical Network Analyzers

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.
