3.5 Diode and Audible continuity Test
1) Connect the black test lead to "COM" socket and red test lead to the "V
Ω
Hz"
socket.
2) Set the selector switch to desired “
” position.
3) Press “SELECT” key to choose Diode or Audible continuity measurement.
4) Connect the test leads across the diode under measurement, display shows
the approx. forward voltage of this diode.
5) Connect the test leads to two point of circuit, if the resistance is lower than
approx. 50
Ω
, the buzzer sounds.
Note:
Make sure the power is cut off and all capacitors need to be discharged
under this measurement.
3.6 Frequency and Duty cycle measurement
1) Connect the black test lead to "COM" socket and red test lead to the
"V
Ω
Hz" socket.
2) Set the selector switch to desired “Hz” position.
3) Press “Hz/%” key to choose Frequency or Duty cycle measurement.
4) Connect the probe across the source or load under measurement.
5) Read the result from the LCD panel.
3.7 Temperature Measurement
1) Connect the black banana plug of the sensor to "COM" socket and red
banana plug to the "V
Ω
Hz" socket.
2) Set the selector switch to desired “
℃
/
℉
” position.
3) Press “SELECT” key to choose
℃
or
℉
measurement.
4) Put the sensor probe into the temperature field under measurement.
5) Read the result from the LCD panel.
3.8 Data Hold
On any range, press the “
” key to lock display value, and the “DH” sign
will appear on the display, press it again to exit.
3.9 Back Light
On any range, press the “
” key over 2 seconds to light the back light,
press it again for more than 2 seconds to wink the light.
3.10 Relative measurement
Press the “REL
△
” key, you can measure the relative value and “
△
” sign will
appear on the display, the auto range mode is changed to manual range mode.
Press it again to exit relative measurement and “
△
” sign disappears, but you
can not go back to auto range mode. This function is non effective on Hz/%
measurement.
3.11 Auto/Manual range
The auto range mode is a convenient function, but it might be faster to
manually set the range when you measure values that you know to be within
a certain range.
