will display "OL".
2) When measuring continuity, press the SELECT button again and connect the
probes on both ends of the tested circuit. If the resistance value between the two checked
points is less than about 60Ω, the buzzer will make out a sound. When you need to buzzer
and have an indicator light, press the LIGHT
head light as the buzzer. If want to save power, press the LIGHT button again to turn it off
when the light is off.
3) . Note: The tested circuit must be checked the continuity in the power off state, any
load signal may cause the buzzer to sound, and leading to misjudgment.
4) When measuring the forward voltage drop of the diode, press the SELECT button
once again, connect the probes to both ends of the tested diode and read the forward
voltage drop volts value. When the diode is reversed or the input end is open circuit, the
LCD will display "OL". This function can also measures the operating voltage of the LED.
5) When measuring the capacitance, press the SELECT button again, and connect the
probes to both ends of the measured capacitor (the red probe is connected to the positive
pole of the capacitor) to directly read the capacitance value.
6) There is no manual range function in the capacitor gear. When the capacitance
value is large, the measurement time will be longer. Do not connect an external voltage or a
charged capacitor (especially a large capacitor) to the test terminal. When the large
capacitor is severely leaked or has broken down, in general, the measurement value will be
unstable.
