Digital multimeter
19 / 25
b）When checking the diode, all the powers within the tested circuits must be disconnected and the
capacitance should be sufficiently discharged.
c) When the measurement is completed, immediately disconnect the testlead and the measured circuit.
Diode forward voltage drop
Forward DC current is about
1.0mA, and backward voltage is
about 3.0V.
30Ω Buzzer sounds for a long
time and the resistance of the
two points is measured as 30Ω
Open circuit voltage is about 1.2V
Overload protection: 250V DC or AC peak value.
XIV. Capacitance（C）
1．Press “ “ button and respectively pu t the red and black testleads into “VΩHz”and“COM”.
2．After the instrument is turned on, triggering the“ “ button is the automatic identification measurement
