meter reading.
5. Reverse the probe polarity by switching probe position. Note this reading.
6. The diode or junction can be evaluated as follows:
A. If one reading shows a value and the other reading shows OL, the diode is good.
B. If both readings show OL, the device is open.
C. If both readings are very small or zero, the device is shorted.
NOTE:
The value indicated in the display during the diode check is the forward voltage.
CAPACITANCE MEASUREMENT
WARNING:
To avoid electric shock, discharge the capacitor under test before measuring.
1.
Set the function switch to the
CAP
capacitance position.
2.
Insert the black test lead banana plug into the negative
COM
jack and the red test lead banana
plug into the
CAP
positive jack.
3.
Touch the test probe tips across the part under test.
4.
Read the capacitance value in the display.
5.
The display will indicate the proper decimal point and value.
Note
: For very large values of capacitance measurement time can be several minutes before the
final reading stabilizes. The bar graph is disabled in capacitance measurement mode. The LCD
displays
DIS. C
.Discharging through the chip is quite slow. We recommend the user to discharge the
capacitor with some other apparatus.
FREQUENCY MEASUREMENT
1. Set the function switch to the Hz position.
2. Insert the black test lead banana plug into the negative (COM) jack and the red test lead banana
plug into the positive Hz jack.
3. Touch the test probe tips to the circuit under test.
4.
Read the frequency in the display. The digital reading will indicate the proper decimal point,
symbols (kHz, MHz) and value.
TEMPERATURE MEASUREMENT
1.
Set the function switch to the Type K
o
F or
o
C position.
2.
Insert the Temperature Probe into the input jacks, making sure to observe the correct polarity.
3.
Press the MODE button until “
o
F or
o
C” appears in the display.
4.
Touch the Temperature Probe head to the part whose temperature you wish to measure.
Keep the probe touching the part under test until the reading stabilizes (about 30 seconds).
5.
Read the temperature in the display.
