the test state.
2) Insert the black test lead into the COM jack and the red test lead into
the jack.
3) Connect the red and black test leads to the resistance of the circuit under test.
If the resistance of the circuit under test is less than 50Ω, the buzzer inside the
instrument will sound. If less than 5% buzzer will sound.
Note
：
If the pen is open or the measured line resistance is greater than 200Ω, the display
shows "0L".
4.12 Transistor measurement
Risk of electric shock.
Do not apply voltages up to 36V DC or AC rms at the common
and hFE ends to prevent electrical shock or damage to the
instrument.
1) Turn the rotary switch to the hFE position.
2) first determine the transistor is NPN or PNP type, and then the transistor of the
e, b, c three feet into the hFE test seat corresponding hole.
3) The hFE approximation of the transistor to be measured is read by the liquid crystal
display.
4.13 Capacitance measurement
Risk of electric shock.
To avoid damage to the instrument or equipment under test,
all power supplies of the circuit under test and all high
voltage capacitors should be fully discharged before
measuring the capacitance. Use the DC voltage file to
determine that the capacitors have been discharged.
