Frequency Or % Duty Cycle Measurements - Sonel CMP-400 Manual De Uso

Do not realise measurements if the battery compartment is
open.
In order to realise continuity test it is necessary to realise the
following actions:

place the rotational selector in the position Ω

connect the red test lead to sockets V/Ω/TEMP and the black
one to sockets COM,

press the MODE button until

touch the test probes to the diode under test - forward voltage
will indicate 0,4V to 0,7V, reverse voltage will indicate "OL";
shorted devices will indicate near 0mV and an open device will
indicate "OL" in both polarities,

having done the test disconnect the test leads from the meter.
5.6 Frequency or % duty cycle measure-
ments


connect the red test lead to sockets V/Ω/TEMP and the black
one to sockets COM,

select Hz or % duty with the Hz/% button,

