Multimeter Description
Rotary switch
Input Terminals
Measuring DC Voltage
1) Insert test leads into input terminals(Red to V and black to COM).
2) Set the rotary switch to range; Connect test leads to the power or load under test,
and the positive polarity of the test end will indicate.
Measuring AC Voltage
1) Insert test leads into input terminals(Red to V and black to COM).
2) Set the rotary switch to V range; Connect test leads to the power or load under test.
Measuring DC current
mA terminal. If current goes up to 10A, insert red test lead into 10A terminal.
2) Set the rotary switch to A range; Connect test leads to the tested circuit in series.
The polarity of red test lead will show.
A
Measuring AC Current
mA terminal. If the current goes up to 10A, insert red test lead into 10A terminal.
2) Set the rotary switch to A range; Connect test leads to the tested circuit in series.
Measuring Resistance
all capacitors
Measuring Capacitance
1) Although the capacitance ranges have been protected internally, you still need to discharge
all tested capacitors so as to avoid any damage to the instrument or any measurement error.
Measuring Frequency
1) Insert test leads into input terminals(Red to Hz and black to COM).
2) Set the rotary switch to kHz range; Connect test leads to frequency source. You can read
the frequency reading directly from the display.
Measuring Temperature
1)
terminals
Testing Diodes and Continuity
、
Then set the rotary switch to ; Connect test leads to tested diode. The displayed
reading is the approximate value of forward voltage drop of diode.
2) Connect test leads to the circuit under test, if the resistance between two tested ends
is ＜
Auto Power Off
1) Auto Power Off
2) power off,
