3) Press the function key MENU(Menu) to enter menu items.
If pressing the key ALARM, the buzzer starts up. It will
beep briefly for the normal semiconductor junction; If the
semiconductor junction shorts out, it will beep continuously.
Silicon PN junction drops between 0.5"'-'0.8V as the normal
value. If pressing the key NORMAL, the buzzer will not
start up.
.& Attention:
• If the measured diode is in open circuit or the polarity is
reversed, "0L" will display.
• When measuring the in-circuit diode, all the power within
the measured circuit must be shut off before measurement
and all the capacitors must be discharged.
• Open-circuit voltage of diode test is around 3V.
• Do not input a voltage higher than 30V in AC(rms),AC(peak
42V) or 60V in DC to avoid personal injury.
• After completing all the measuring operations, disconnect
the connection between the test leads and the circuit under
test.
