RM1307731648914587 1. Product Description This Tester is a small tool design for Engineer, Electronic Maintenance and Factory,Its 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 3. Measuring Parameters Resistor: 0-50M Resolution 0.01 Capacitor: 25pF-100mF Resolution: 1pF Inductor:0.01mH-20H Resolution: 0.01mH Capacitor ESR 2F-50mF Resolution:0.01 (ESR:Equivalent Series Resistance) 4 Use Introduction a. Power ON: Pre POWER/TEST button before to use, this meter design 2POWER/TEST button, the function is the same. Easy for both left and right hand habit people to use. b. Test: Pre POWER/TEST button to start a test. Regardle of the pin sequence, this meter will recognizes the pins 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 preure on device for better connection f. Electrolytic Capacitor Discharge: Support max 2000F/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 pre button g. Selection Menu:A long button pre(>0.5s) will enter the selection menu for additional functions. Short button pre to switch different functions,and long button(>0.5s) to enter submenu. Switch off: Long button pre to Power Off immediately . Transistor Exit Selection Menu, return to transistor test. Frequency:Reserved. f-Generator:With the button pre 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 pre (0.5s,
