Description

LCD Digital ESR Transistor Meter M328 Resistor Diode Capacitor Mosfet Tester
1. Product Description
This Tester is a small tool design for Engineer, Electronic Maintenance and Factory,It’s very easy to test plug-in and SMD devices, also can test different kinds of Diodes, Triodes, Thyristors, MOSFET; able to analysis the device type, the polarity of the pin, the output HFE,
the valve voltage, the junction capacitance of the FET
2. Attention
● Always be sure to discharge capacitors before connecting them to the Tester!
● If using DC supply please choose DC 9V-12V adapter
.
● When the battery power is under 6V, please replace a new one

4 Use Introduction
a. Power ON: Press “POWER/TEST” button before to use, this meter design 2“POWER/TEST” button, the function is the same. Easy for both left and right hand habit people to use.
b. Test: Press “POWER/TEST” button to start a test. Regardless of the pin sequence, this meter will recognizes the pin’s function and layout on the screen.
c. Power OFF:
Automatically power down if no button operation in 20 seconds.
d. Test Socket: With 3 test sockets, SMD Socket, Plug-in Devices Socket and Probe Socket.
The port 1, 2, 3 of each socket are the same, they are connected internal.
e. SMD Device Test: Test via SMD socket or Probe. While using SMD socket, put some pressure on device for better connection
f. Electrolytic Capacitor Discharge: Support max 2000μF/50V capacitor discharge with the internal 1K/1W resistor, and discharge for 2 seconds at least. Use external discharger while the capacity is higher
Discharge is stand alone function, no need to power on or press button
g. Selection Menu:A long button press(>0.5s) will enter the selection menu for additional functions. Short button press to switch different functions,and long button(>0.5s) to enter submenu.
● Switch off: Long button press to Power Off immediately
.● Transistor Exit Selection Menu, return to transistor test.
● Frequency:Reserved.
●f-Generator:With the button press can select different frequencies output from T2(Test Port 2), and T1,T3 will be the reference gr-ound.
Frequencies selectable from1 Hz to 2 MHz
, amplitude is 5V
● 10-bit PWM: Generates a 7.8KHz frequency with selectable pulse width at the pin T2. With a short button press (<0.5s) the pulse width is increased by 1%, with a longer button press(>0.5s, <1.3s)
the pulse width is increased by 10%.
●C+ESR@TP1:3: It's a stand-alone capacity
measurement with ESR measurement at the test pins T1 and T3.
rotary encoder:Reserved
.● Selftest:Full selftest with calibration
●Contrast:Contrast value for a graphic display,
selectable from 33 to 55
.Note In Selection mode, the Tester will auto power off after
8 minutes without any button press.
5. Function Description
● Automatic detection of NPN and PNP bipolar transistors, N- and P-Channel MOSFETs,JFETs, diodes, double diodes, Thyristors and Triacs.
●
Measuring of current amplification factor and Base-Emitter threshold v-oltage of bipolar transistors.
● Detection of the protection diode of bipolar transistors and MOSFETs.
● Measuring of the Gate threshold voltage and Gate capacity value of M-OSFETs
● The inductance measuring range is from 0.01mH to 20H,out of range or if the resist or higher than 21KΩ will be shown at resistor
.
● Testing time is about two seconds, only capacity or inductance measurement can cause longer period.
● Small Devices Container is design for placing the small size components
.● TheProbe socket support different kinds of
probes.
● With a Typical ESR Value of Electrolytic Capacit
or table on the cover, easy for user to judgment
the detected capacitor's quality. The ESR table is
for reference only, use the manufacturer's data asstandard.
5. Calibration
● Short
T1,T2,T3 to one, then press button.
● When LCD shows “Selftest mode.. ?”, press button within 2 seconds to enter calibration mode, otherwise will come into transistor test mode.
● Tester automatic calibrating until LCD shows “isolate Probes!”, then separate T1,T2 and T3.
● Wait a few seconds until LCD shows “Test End”
