CONTINUITY TEST
WARNING: DO NOT APPLY VOLTAGE TO MEASURING TERMINAL
WHILE RANGE SWITCH IS IN OHM POSITION.
Set the selector switch to the BUZZ range. Connect the test leads to two
points of circuit. If the resistance is lower than 200 Ohm approx., the Beeper
sounds.
Note: Battery voltage is sufficient for Buzzer operation as long as the
Zero Ohm pointer can be adjusted to the Zero scale place.
Note: If connected incorrectly with the voltage, quickly remove the test
leads from the circuit as to avoid damage to this tester.
(This tester can afford the voltage <250V DC/AC rms. for the period of 5
seconds max.)
Transistor hFE and LED Test
Set the selector switch to the Ω X 10 range.
For Measuring Transistor hFE
1. 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.
1. Read the approximate hFE Value directly at the hFE scale.
Note: Current 10μA. VCE 2.8V.
2. 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 can come 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.)
