4.
If the resistance is < 50
Ω
,
a tone will sound.
Diode Test
1.
Connect
as described for resistance measurements
2.
Press the
MODE
button to select diode test
.
3.
Touch the test probe tips to the diode or semiconductor junction under test. Note the meter reading.
Reverse the test lead polarity by reversing the red and black leads. Note this reading.The diode or junction can be evaluated as
follows:If one reading displays a value (typically 0.400V to 01.800V) and the other reading displays
OL
, the diode is good. If both
readings display
OL
the device is open.If both readings are very small or ‘0’, the device is shorted.
Capacitance Measurements
WARNING:
To avoid electric shock, discharge the capacitor before measuring.
1.
Press the
MODE
button to select capacitance measurements.
2.
Insert the black test lead banana plug into the negative
COM
jack.
Insert the red test lead banana plug into the positive
jack.
3.
Touch the black test probe tip to one side of the device.
Touch the red test probe tip to the other side of the device.
4.
Read the capacitance value in the display.
Note: For very large values of capacitance measurement time can be several seconds before the final reading stabilizes.
Note: The Zero feature removes stray test lead capacitance to improve the accuracy of low value capacitance measurements. To
perform a zero, Press and hold the
MODE ZERO
button for two beeps. The display will zero. The offset value is now stored and is
removed from all measurements.
.
Frequency and Duty Ratio Measurements
1.
Rotate the function switch to the
Hz %
Position.
2.
Insert the black test lead banana plug into the negative
COM
jack.
Insert the red test lead banana plug into the positive
Hz
jack.
3.
Touch the black test probe tip to one side of the device.
Touch the red test probe tip to the other side of the device.
4.
Read the Frequency value on the upper large display.
Read the Duty Ratio on the lower small display.
5.
Press the
MODE
button to display the Duty Ratio on the large
display.
Power and Measurement
1. Rotate the function switch to the
KW/KVA
Position.
2. The connecting method see right figure.
3. Press the
MODE
button to select AC or DC power.
4. Press
COS
θ
button to select KVA ,KW,or Power Factor.
Type K Temperature Measurements
1.
Rotate the function switch to the
Temp
position.
2.
Press the MODE button to select °F or °C.
3.
Plug the transfer socket into the negative COM jack and the positive V jack, then insert t
he TYPE K into the transfer socket, make sure that the positive and negative feet are c
onnected correctly.
4.
Connect the temperature probe tip(s) to the object which will be tested.
5.
Read the temperature on the display.
Note:
In case of an open input or a temperature overrange, the meter will display “
- - - - -
” .
Data Hold
To freeze the LCD reading, press the
HOLD
button. While data hold is active, the
HOLD
icon appears on the LCD. Press the
HOLD
button again to return to normal operation.
MAX/MIN
1. Press the
MAX/MIN
button to activate the MAX/MIN recording mode. The display icon "
MAX
" will appear. The meter will begins
recording and displaying the maximum value measured.
2. Press the
MAX/MIN
button and “
MIN
” will appear. The meter will display the minimum value measured during the recording session.
3. Press the
MAX/MIN
button and “
MAX
MIN
” will appear. The meter will display the present reading, but will continue to update and
store the max and min readings.
4. To exit MAX/MIN mode press and hold the
MAX/MIN
button for 2 seconds.
