1. Introduction
The Tester is specifically used to measure SMD
（
Surface Mounting
Device). There are Chip type resistor, Chip type capacitor and diode,
for example. Moreover, the Tester has the continuity checking
function. The Tester automatically identifies the passive component.
The Tester is designed to meet IEC1010-1 standard and
Stipulation of 2-Pollution Grade.
2.Safety Note
The following safety notes should be observed prior to using
This Tester and any associated accessory. Although the Tester is not
used to measure DC/AC Voltage or Current, there are situations
where hazardous conditions may be present.
● Inspect the Tester case before using. Do not use damaged device.
● Inspect the Pin Holder and Pin gold-plated state.
● Do not attempt use the Tester as tweezers to prevent the pin tip
from damage.
● Do not apply external voltage between the two pins.
● Do not used in the environment with explosive gas, vapor, or dust.
Caution: Never use the Tester on live circuits.

5. Testing Operation
“F” push button is the function select key to choose manually
Resistance, Continuity, Diode or Capacitance test. The tester default
preset is auto scanning.
5-1. Scanning Mode
Once the 3V Lithium battery installed, it will auto power on
immediately and LCD will
displayed „SCAN‟ and „ - - - - ‟ sign.
Caution
When measuring SMD device on the PCB, please
disconnect power and discharge all high- voltage
capacitors.
5-2. Resistance measurement
[1] Auto scanning mode & a
uto range: 300.0Ω — 3.000MΩ
[2] Selected resistance measurement mode by the
“FUNC” key: the
range is extended to 30 MΩ, i.e.300.0Ω — 30.00MΩ
When overloaded
, the „OL‟ symbol will be displayed on the LCD.
5-3. Capacitance Measurement
[1] Auto scanning & Auto range: 3.000nF
— 300.0uF
。
[2] Selected Capacitance Mode by the „FUNC‟ key:
The range is extended to 30.00mF, i.e. 3.000nF
—30.00mF.
Caution
To avoid damage to the tester or to the equipment under test,
disconnect power and discharge all high-voltage capacitors before
measurement.
5-4 Diode Check
This function is used to check diodes, transistors and other
semiconductor devices. In the diode test mode, it will send a current
through the semiconductor junction, and measure the voltage drop, a
good silicon junction drop is between 0.5V
— 0.8V.
For forward voltage drop on any semiconductor component, the test
pin (
"INPUT‟ terminal) touch component anode and another test pin
touch component cathode. The measured value show on the LCD.
Reverse the test pin and measure the voltage across the diode
again.
If diode is good, the display shows “OL”.
If diode is shorted, the display shows 0 (zero) in both directions.
If display shows “OL” in both direction, the diode is open.
5-5. Continuity Check
When the resistance reading is less than 30Ω, the buzzer generates
a 2KHz beep to indicate continuity.
5-6. Hold function
In the data hold mode, the tester will hold the present measuring data
until pressing of
the “HOLD” key once again.
6. Maintenance
6-1. Replacing The Battery
When meter displays
, the battery must be replaced to
maintain normal operation.
6-2. Cleaning
The meter can be cleaned with a soft clean cloth to remove any oil,
grease or grim. Do not use liquid solvent or detergent.
