Dc And Ac Currents; Currents (A Dc And Ac) - Chauvin Arnoux C.A 5001 Notice De Fonctionnement

5 - DC AND AC CURRENTS

Always switch off the circuit to test before connecting the
multimeter to the circuit. If the "Fus." light comes on, change the
faulty fuse(s) (Reminder: minimum voltage of 80 V).
Connect the leads to the multimeter and connect in series to
the circuit with:
- the red lead in the "mA" terminal, up to 500 mA
- the red lead in the "5 A" terminal, from 500 mA to 5 A
Switch off the power supply to the circuit before changing
range.
I When the order of magnitude is not known, place the switch on the
highest range then progressively lower to the appropriate range.
I To get the current in mA or A, multiply the value read on the
appropriate scale by the reading coefficient shown in the table.
