For silicon PN junction generally 500~800mV is
confirmed to be the normal value.
Note:
•
“OL” will be displayed when the measured diode is
open-circuit or the polarity is inversely connected.
•
Before measuring diode, the power circuits being
measured shall be powered off and all capacitors
shall release residues of electric charged to assure
the measurement accuracy,
•
The test open-circuit voltage of diode is approximately
3.5V.
•
Do not input voltage higher than 30V DC or AC, as it
may cause personal injury.
•
After completing all measurement operations,
disconnect the test pen from the measured circuit.
CAPACITANCE MEASUREMENT
•
Insert the red test pen into the “
V
” jack and the black test pen into the “COM”
jack. Measure by REL mode.
•
Push the range switch to the measurement gear “ ”, press
SELECT
to select
“capacitance” and connect the test pen in parallel with the two terminals of
measured capacitance.
•
Directly read out the capacitance value of the measured circuit from the display.
•
It is recommended to carry out the capacitance measurement with test short line
input, thus reducing the impact caused by distributed capacitance.
Note:

•
If the measured capacitance is short circuited or capacitance exceeds the
maximum range of the meter, the display will show “OL”. Under capacitance
measurement mode, the simulation bar indicator is
forbidden.
It will take a longer time to achieve the correct reading
when measuring capacitance larger than 600µF.
To ensure the measurement accuracy, it is
recommended to discharge all residual charges in the
capacitor before the test.
Then, input the meter for measurement, which is
particularly important to the capacitor with high
voltage.
It is required to prevent damage to the meter and
personal injury.
After completing the measurement operation,
disconnect the test pen from the measured
capacitance.
