AstroAI AM33D - Square Wave Output

DIODE TEST TIPS:
• Is the diode functioning correctly: If the red test lead is
connected to the positive pole of the diode and the black
lead is connected to negative, then the diode should be in a
forward conduction state, and the displayed value is the
forward voltage drop.
• Normal diode forward pressure drop: the general silicon
tube is 0 5-0.7 V, germanium tube is 0.15-0 3V
• You can also verify that the red test lead is connected to the
negative pole of the tested diode and the black test rod is
connected to the positive pole. The diode should display' 1"
POLARITY JUDGMENT METHOD:
• Switch the Multimeter to the Resistance setting
• Connect the two test leads to the two electrodes of the
diode.
• Measure one result, then swap the positions of the test
leads and measure the second result.
• The larger result is the reverse resistance and the smaller
result is the forward resistance. The smaller resistance is
when the black test lead is connected to the positive end of
the diode and the red lead is connected to the negative end
w.SQUARE WAVE OUTPUT:
• Insert the red test lead into the "VQmAJ1r" terminal and the
black test lead into the "COM" terminal.
• Turn the rotary dial to the continuity test,
touch the red test lead and the black test
lead to check whether they are normal The
buzzer will beep if the test leads are normal.
