3. Short the leads by touching the probes together. Pointer should
read zero at the right hand end of the uppermost scale, if it
doesn’t, use the Ohm adjust knob on the right hand of the panel
to line up the pointer with zero. ( If pointer can’t be brought to
zero, replace battery.)
4. Connect the test leads across the resistance to be measured.
5. Take reading on the top “” scale and multiply it by the
multiplication factor indicated by the selector switch.
6. If there is little or no pointer movement from the left side of the
scale, reset the selector switch to higher range. The effective
reading scope on an Ohm meter scale is within the area of
between 25 degree of Arc left side to the Midscale and 25
degree right side to the Midscale.
Note: If connected incorrectly with the voltage, quickly
remove the test leads from the circuit as to avoid the damage
to this tester. (This tester can afford the voltage <250V DC/AC
rms. for the period of 5 seconds max.)
Diode Measurement
Set the selector switch to the appropriate range to be used.
NOTE: To test the diode while current below 0.060 mA at X
10K range; current below 0.15 mA at X 1K range; current
below 1.5 mA at X 100 range; current below 15 mA at X 10
range; current below 150 mA at X 1 range.
For IF (forward current) test
Put the BLACK test lead to the “-COM” jack and the RED test
lead to the Red “+” jack. And then connect the Black probe to
the Positive terminal of the Diode, the Red probe to the
Negative terminal of the Diode.

For IR (reverse current) test,
reverse the connection.
1. Read the value IF or IR of the diode on the LI scale.
2. Read the linear (forward voltage) VF of the diode on the LV
scale.
Transistor hFE and LED Test
Set the selector switch to the R 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 10A. 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.)
Note: If connected incorrectly with the voltage, quickly
remove the test leads from the circuit as to avoid the damage
to this tester.
(This tester can afford the voltage <250V DC/AC rms. for the
period of 5 seconds max.)

Decibels Measurement
1. Set the selector switch to AC 10V range.
2. Connect the BLACK test lead to the “-COM” jack and the
RED test lead to the “Output” jack.
3. Connect the test leads to the measuring circuit, and then
read the bottom Red dB scale.
4. For more dB scope, change the selector switch to the others
of ACV ranges and make the same actions. Add the
appropriate number of dB scale reading as noted on the
chart below.
Note: For absolute dB measurements, circuit impedance
must be 600 Ohm. 0 dB = 1mw dissipated in a 600 Ohm
impedance (equivalent to 0.755V across 600 Ohm)
ACV RANGE ADD dB Number
