„ Use: Zero level of the red scale in dB corresponds to U
range. The reading is direct in dB for the 10 V
For the other ranges, it is possible to read in dB (near value) by adding respectively:
+10 dB on the 30 V
+20 dB on the 100 V
+30 dB on the 300 V
+40 dB on the 1000 V
DC AND AC CURRENTS
Always switch off the circuit. If the «Fus» light comes on, change the faulty
fuse(s) (Reminder: minimum voltage of 110 V).
Connect the leads to the multimeter and connect in series to the circuit with:
- the red lead in the «µmA» terminal, up to 1.5 mA
- the red lead in the «15 A» terminal, from 1.5 A to 15 A
Switch off the power supply to the circuit before changing range.
„ To get the current in µA, mA or A, multiply the value read on the appropriate scale
by the reading coefficient shown in the table.
