Features:This instrument is an instrument developed for electronics engineers, developers, electronic repair, production plants and enthusiasts.It is very easy to test plug-in and SMD devices, also can test different kinds of diodes, triodes, thyristors, MOSFETIt enable you to analysis the device type, the polarity of the pin, the output HFE, the valve voltage, the junction capacitance of the FET.Automatic shutdown function, avoid unnecessary waste, save battery power, improve battery life.A reference for the transistor, MOSFET protection diode and amplification factor that can detect the transistor emitter forward bias voltage.SpecificationTypes: A(Without Clip), B(With Clip)Material: Plastic, electric componentsColor: Black, redSize(L x W x H): About 14 x 8.2 x 4.6 cmResistance: 0-50M. Resolution: 0.01.Capacitance: 25pf-100mf. Resolution: 1pf.Inductance: 0.01mH-20H. Resolution: 0.01mH.Measuring capacitance ESR resolution: 0.01.Matters needing attention:Be sure to discharge the capacitor before testing it, otherwise the meter may be damaged.When using adapters for power supply, use adapters in the DC 9V-12V (including 9V, 12V) voltage range.This meter will not charge the battery. When the battery power is lower than 6V, please replace the battery in time.When discharging the capacitor, discharge can be realized without starting up.Usage:A. Press "Start up/Test" to realize the function of starting up and testing once. Press this key repeatedly for multiple tests;Automatic shutdown after 20 seconds without operation.B. The meter provides three measurement methods, namely patch, plug-in and external table, and 1, 2 and 3 of each method have the same corresponding relation.C. There is no need to distinguish the discipline sequence when placing the device. After the measurement, the corresponding device function of each pin will be displayed on the screen.D. A reference table of ESR typical values corresponding to electrolytic capacitors is printed on the back of the instrument. The table is for reference only.Calibration:Short connect 1, 2, 3 test points, press "Power on/Test" button, the screen prompts whether to enter calibration, press "Power on/Test" button to confirm and enter calibration within 2 seconds.After that, the screen prompts to disconnect 1, 2, and 3 test points, and then continue to disconnect until the end of the prompt calibration.New features:1. DC power interfaceVoltage input range: 9V ~12VConvenient factory needs long or long time testing, battery saving, and environmental protection2. Start/test the buttonBig body: People with big hands are also easy to operateLeft and right keys: function the same, suitable for left and right hand habits of people3. Small element placement areaWhen measuring small devices, the device is easy to drop, such as shaking, wind blowing, sneezing, the device may be lost.Having such a placement area is of great convenience.There are three cells, you can put a variety of different components, in the operation of the test, easy to find.Package included:Choice A:1pc x Resistance meter1pc x User manualChoice B:1pc x Resistance meter1pc x Clip1pc x User manualNotice:Due to the light and screen difference, the item& 039;s color may be slightly different from the pictures.Please allow 0.5-2cm differences due to manual measurement.
