The C.A 5231 is a TRMS digital multimeter, specially designed
to combine in a single instrument the various functions and
measurements of the following electrical quantities:
AC
voltmeter
measurements in the fields of electricity and electrical
engineering);
AC and/or DC voltmeter with high input impedance (voltage
measurements in the field of electronics);
Ohmmeter;
Continuity test with buzzer;
Diode test;
Ammeter (measurement by clamp-on ammeter);
Contact-free detection of presence of network voltage (NCV
function, presence of phase).
