Test Method. (i.e. the LCD displays "
(2) Insert the red lead into "V. " input terminal and the black lead into "COM" input terminal.
(3) Connect the test leads crossly with the tested circuit, the inner buzzer sounds if the resistance is less
than (50+20)
.
(4) Press "SEL" button to select the Diode Test Method. (i.e. the LCD displays "
(5) Forward Measurement: Connect the red test lead with the positive polarity of the tested diode, and the
black test lead with the negative polarity of the tested diode, the LCD displays the approximation of the
diode forward voltage drop.
(6) Backward Measurement: Connect the red test lead with the negative polarity of the tested diode and the
black test lead with the positive polarity of the tested diode, the LCD displays "OL".
(7) The complete diode measurement includes forward and backward measurements. If the testing result
doesn't comply with the above, it indicates the diode is fault.
Note: Do not input any voltage at this range.
4-9. Hold
Date Hold: Press the date hold button, the current date is held on LCD; Press the button again, the date hold
function is cancelled and get into further measurement.
4-10. Auto Power Off
