Measurement Operation(10)
Note
l
In a circuit, a good diode should still produce a forward
voltage drop reading of 0.5V to 0.8V; however, the
reverse voltage drop reading can vary depending on
the resistance of other pathways between the probe
tips.
l
Connect the test leads to the proper terminals as
said above to avoid error display.
l
The LCD will display OL indicating either open circuit
or wrong polarity connection.
l
The unit of diode is volt (V), displaying the positive-
connection voltage-drop value.
l
Open circuit voltage approximate 2.8V.
l
When diode testing has been completed, disconnect
the connection between the testing leads and the
circuit under test and remove the test leads away
from the input terminals.
H. Capacitance Measurement
(see figure 8)
( figure 8)
Warning
To ensure accuracy, the Meter inside is discharged
against the tested capacitor. DIS.C will be shown
on the display when it is under discharging, this
process will be quite slow. To avoid damage to the
Meter or to the equipment under test, disconnect
circuit power and discharge all high-voltage capacitors
before measuring capacitance.
Use the DC Voltage function to confirm that the
capacitor is discharged.
