21

The C.A 6460 and C.A 6462 are ohmmeters equipped with
digital displays for earth and resistivity measurements in the
field.
They are particularly well-adapted to use in difficult conditions,
in the presence of interference voltages, high earth currents
or highly resistive auxiliary connections, in accordance with
standards NF EN 61010-1 + A2, NF EN 61557 parts 1 and 5,
NF EN 61326-1 + A1.

For easier handling, the instrument is equipped with:

■

a single pushbutton for activation of measurement,

■

a large-size backlit liquid crystal display,

■

three LEDs indicating the presence of faults which may
invalidate the measurement result,
