For testing earth connections... whatever the installation configuration!

Innovative and and user-friendly, the C.A 6456 earth and loop tester is particularly easy to use and also offers high metrological performance for testing installations' compliance with the European and international standards: NF C 15-100, IEEE, VDE 0100, NIN/NIV, OVE EN-1, etc.

* direct, safe connection to installation mains
* reliable measurements due to automatic permutation of L and N inputs if conductors are
  reversed at socket connection
* automatic installation voltage and frequency measurement
* POWER-OFF earth resistance measurement on installations using conventional auxiliary earth
  rods (3P or 2P)
* POWER-ON earth resistance measurement of installation: ground loop and 1P earth with
  choice of measurement current (high for precision measurements or low so as not to trigger
  differential devices)
* loop resistance and impedance: L-N, L-L, and L-PE from 0.20 to 4 kΩ
* short-circuit current displayed up to 40 kA by calculation (Uref/ZL-PE)
* clamp measurement of current and leakage current (option)
* Cat. III, 600V
* programmable alarms, date-stamped recording of measurement readings, data printout using
  standard printer, direct transfer of data to PC (data transfer application included as standard)
* large backlit display / "hands-free" pouch
* battery operated - battery life: 2,000 tests
* dimensions: 270x250x180mm ; weight : 900g
