Description:
The tester uses 3.7V rechargeable lithium battery (battery model: 14500), but you can use the T-MINI USB socket to charge the battery and power the system, is more economical and convenient for a long time in the indoor use.
Specification:
| Operating System | ATmega328 microcontroller |
| Display | LCD with back light, 2×16 characters |
| Power Supply | 3.7V rechargeable lithium battery (battery model: 14500) or 5V USB port power supply. |
| Shutdown Current | 20nA |
| Resistance Measurement | 0-50MΩ, accuracy is 0.1Ω |
| ESR Measurement | 2UF or higher value capacitor, accuracy is 0.01Ω and a two-digit numeric display |
| Capacitance Measurement | Max. four numbers and units display, measuring range 25pf to 100mF, Resolution up to 1 pF (@ 8MHz clock). * discharge it before testing. |
| Inductance Measurement | (Resistor value lower than 2100Ω) Range from 0: 01mH than 20H, but the accuracy is not good. Measurement results show only a single connection element. |
| Automatic Detection | PNP and NPN bipolar transistor, N, P-channel MOSFET, JFET, diodes, dual diode, thyristor SCR, pin layout, etc |
| Other Measurements | Threshold voltage of emitter junction and current amplification factor of the bipolar transistor. |
| Other Functions | Find out all the full-bridge connection by measuring it only once |
| Testing Time | about 2 seconds, only the capacitance and inductance measurements require longer time. |
Correction:
Short connect three test terminal, enter the test, the screen prompts correction step. When prompted to disconnect nipple, disconnect the three test, calibration will continue, when prompted connect 100nF capacitor above in the 1-3 foot, program will automatically enter the next step. Until the end of the correction to restart, can complete the correction.
Features:
- One key measure operation, automatically shut off the power when delay. Support for battery operation.
- Automatic detection PNP and NPN bipolar transistor, N, P-channel MOSFET, JFET FET, diodes, two diodes, thyristors, resistors, capacitors, inductors. Automatic detection pin definitions.
- Measurement of the bipolar transistor current amplification coefficient (B) and emission of conduction voltage (Uf). Darlington transistor can be identified by the amplification factor of the high threshold voltage and high current.
- Can detect bipolar transistors and MOSFET's internal protection diodes and displayed on the screen.
- Measuring the threshold voltage and the gate capacitance of the MOSFET.
- Support two resistance measurements, the potential can be measured. If the potentiometer is adjusted to its end, the tester can not distinguish between the middle and the ends of the pin.
- Resistance measurement resolution is 0.1 ohms, the maximum value is 50M ohms measurements.
- Capacitance measurement range from 25pf to 100mF (10 UF). Resolution up to 1 pF, inductance measurement range is 0.01MH-20H, otherwise it will appear as a resistor, if inductor DC resistance is higher than 2100Ω will also be displayed as a resistor.
- Can detect 2UF above capacitor equivalent series resistance (ESR), the resolution is 0.01 ohms. This feature is very important for the detection of the capacitor performance.
- Can display symbols of the two diodes in the right direction, also shows the positive voltage drop.
- For evaluation of a LED diode, positive voltage drop higher than normal. Double light emitting diode detection for the double diode. Simultaneous detection of the light-emitting diode will flashes.
- Each test time is about two seconds, only large capacitance and inductance measurement will need a long time.
Note: When installing the battery for the first time, you need to activate the battery.
Method 1: After installing the battery, use tweezers or shorting line shorted connect the following two holes.
