Transistor hFE and LED Test
1. Set the selector switch to the R X 10 range.
FOR Measuring Transistor hFE
2. Take note the type of transistor “PNP” or “NPN” and then insert
the transistor terminals of the Emitter, Base and Collector
separately into the proper holes of the socket on the front panel.
3. Read the approximate hFE Value directly at the hFE scale.
Note: Current 10μA. VCE 2.8V.
4. When the Base terminal cut, the value of Leak is Iceo for
Transistor.
FOR Measuring LED: Insert the transistor terminals directly into
the “+” and “-” holes of the socket on the front panel.
And then check if the LED under testing is lighting.
Battery Check
1. This meter comes with two separate battery check ranges to test
either DC 1.5V or 9V batteries.
2. Set the selector switch to the appropriate BATT range to be
used.
3. Connect the BLACK test lead to the “-COM” jack and the RED
test lead to the Red “+” jack.
4. Connect the Red test lead to the positive end of battery and the
Black one to the negative end of the battery to be measured.
5. Take reading on the “BATT” scale and check it good or bad as
per which portion indicated.
(Note: the mark section of “?” shows that the battery may be
starting to decay.)
Note: If connected incorrectly with the voltage, quickly remove
the test leads from the circuit and can avoid the damage to
this tester.
(This tester can afford the voltage <250V DC/AC rms. for the
period of 5 seconds max.)
