Current Source
Current source applies to the diode measurement function. The current selected is
applied to the diode under test and the multimeter measures the voltage drop
between the two ends of the diode to determine the polarity of the diode.
Note: when measuring diode with relatively larger drain current, do not use the
small current source (as the forward voltage drop measured might be too low to
determine the polarity of the diode).
In DIODE measurement, press
to enter the following interface. The current
sources available are 1 mA, 100 μA, 10 μA, 2 μA and 200 nA and the corresponding
voltage ranges are -0.2 V ~2.2 V, -0.2 V ~4.2 V, -0.2 V ~4.8 V, -0.2 V ~5.2 V and
-0.2 V ~5.5 V. You can also press
to select the desired current source.
