Product Introduction
Description:
LCD GM328B Transistor Tester Diode ESR Meter PWM Square Wave Generator
Resistance measurement maximum resolution 0.01Ω, can be measured up to 50MΩ.
Can measure a capacitor, capacitance range 25pf~100mF, resolution is 1pF.
Capacitance less than 25pF can be measured by parallel connection another known capacitor is greater than or equal to 25pF.
Support two diodes to be measured simultaneously and display voltage drop for diode.
Automatically test the pins of a component and show on the display.
Resistance less than 2100 ohm while it's equivalent inductance measuring range from 0.01mH-20H.
Program tape self checking function, Support calibration of multiple parameters.
Can be used as frequency meter and frequency generator: frequency range from 1Hz-2MHz and can output 10-bit PWM signal.
Notice:
Before measuring capacitance, the capacitor must be discharged, otherwise very likely damage the meter.
Be sure to disconnect the power from the circuit board when testing the components on the circuit board, the test equipment have residual voltage is not allowed.
Type: Assembled Tester
Display: 1.8inch 160*128 LCD
Power Supply: DC 7-12V
Current: Approx. 20nA
Resistance Measurement: Max. 50MΩ
Resistance Resolution: 0.01Ω
Capacitance Measurement: 25pF~100mF
Capacitance Resolution: 1pF
Inductance Measurement: 0.01mH~20H
PCB Size: 7.5 * 6cm / 2.95 * 2.36in
Product Weight: 50g / 1.79oz
Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
Old Version
New Upgrade Version
Low Base without Battery Base
New Upgrade Version
High Base with Battery Base
There is no welding battery holder on the board, but there are reserved welding points.
Power can be supplied through the DC interface, or the battery holder can be welded by itself.
The base is welded with a 9V square ba
ttery ho
ld
er on the PCB board, which can be powered by a DC interface or a battery.
The product has no battery charging function and cannot be powered by the DC interface and battery at the same time.
Compared with the old version, the new version is only modified and upgraded in hardware. The display is placed on the motherboard, and the chip and other patch components are placed under the PCB board, protected by the base; the DC connector and button cap are replaced,
Use four large mushroom head screws to fix the PCB and the base, the structure is stable and solid, and the metal feels full.
The high base version has a built-in battery box, which makes it more convenient to use.
The software has not been upgraded. The source code of the product is open source code, which is a learning and discussion program. The product is more inclined to learning and teaching products. It is normal for testing bugs such as inaccurate test data to occur. After-sales cannot solve this aspect temporarily.
The problem.
If there is a hardware problem that cannot be lit or the key operation is invalid, you can contact the after-sales service for solution.
