leads and then subtract it from the real measurement result.
Diode and continuity testing
RANGE
DISPLAYING
TESTING CONDITION
Forward voltage drop of diode
Forward DCA is approx. 1mA,
the backward voltage is approx
3V
Buzzer makes a long sound
while resistance is less than
(70±20)Ω
Open voltage is approx. 3V
Overload protection
：
DC 250V or AC peak value.
Bartery test:
At 1.5V range, overload inside is 15Ω, working current is 100mA
At 9V range, overload inside is 900Ω, working current is 10mA
