NOTE:
1.If the capacitance range under measured is unsure beforehand, should set the range knob to the
highest range, then, set to a proper range according to the displayed value.
2.If LCD displays“1” , it means over range, should set the range knob to a higher range.
3.Before measuring, LCD display might not be zero, the residual reading will be decreased
gradually and could be disregarded.
4.When measuring large capacitance, if creeps seriously or break capacitance, LCD will display some
instability value.
5.Discharge all capacitors completely before capacitance measurement to avoid damage.
6.UNIT: 1uF =1000nF 1nF=1000pF
4.8 DIODE AND CONTINUITY TEST
1.Insert the black test lead to “COM” terminal and the red one to V/
Ω
jack( Note: the polarity
of red test lead is“+”).
2.Set the range knob to“
”range, connect the test leads to the diode under measured,
reading is the approximation of the diode positive volt drop.
3.Connect the test leads to two points of the measured circuit, if buzzer sounds, the resistance is
lower than approx.(70±20)
Ω
.
4.9 TRIODE hFE
1.Set the range knob to hFE.
2.Verify the type of the transistor is NPN or PNP, insert the emitter, basic and collector to the proper
jack on test accessory.
4.10 AUTO POWER-OFF AND LCD BACKLIGHT ON
When power on ,LCD screen showing “APO” ,mean the meter in
automatic power-off mode , After 15
minutes, the meter is auto power-off to be in sleepy mode . Shortly and repeatly press LCD backlight
key , light on/off . If no need auto power off , press LCD backlight key for 2 seconds , the “APO” will
