(3) Do not input any voltage at this range.
4-8. Continuity, Diode Test
(1) Set the range selector knob to " ,
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
Stop using the instrument for 30 minutes, the instrument will be auto power off, and get into the sleeping
mode; if restarting the power, set the selector knob to OFF position, it will be restarted.
Note: Please turn off the power after use for lengthening the life of battery.
5. Instrument Maintenance
This is a high precise instrument, don't try to modify the circuit optionally, and note the following points.
(1) If " " symbol displays, should replace the battery in time.
(2) Before replacing the battery, please keep the test leads off the tested point, turn the power off, and
unlock the screw, then replace the battery.
(3) Do not expose the instrument to the direct sunshine, do not use and store the instrument under the
circumstance of the high temperature, high humidity, and combustible, explosive, and strong magnetic
place.
(4) Keep the instrument away from water, dust and shock.
(5) Regularly wipe the instrument case with detergent, do not use the abrasive or solvent.
6. Fault Elimination
If the instrument doesn't work properly, check it as the follows:
