Attach the black (negative) terminal with the Cathode pin and the red (positive) with the Anode pin The multimeter reads nothing because the SCR is not turned on If the multimeter stays on certain value all the time, the SCR is shorted Hook a load, a resistor, and the BT151 in series...
1482137 Testing transistors SANWA INSTRUMENT WORKS Ltd 14 Aug 1974 [21 April 1974] 35818/74 Heading G1U [Also in Division H2] A test lead comprises a housing 1 with a contact pin 2 connected to two lead wires 5, 6, one wire 5 being in series with a resistor 7. In use, the pin ...
1, will use multimeter testing instruments and equipment; 4, familiar with the inverter, switching power supply, and power devices. 9, a strong sense of responsibility, can work under pressure to maintain a positive attitude. 10, a good sense of service. ...
Precision resistors below $100 will not come with a test report which states what the resistance actually is. You just know that the resistance will be to the specified tolerance. So a 1\$\Omega\$ 0.1% resistor could be 0.99\$\Omega\$ or 1.01\$\Omega\$ or somewhere in between. ...

Though small and simple, the diode is an essential part of modern electrical systems. By controlling the flow and direction of current, diodes enable countless applications of modern electronics.
A digital multimeter (DMM) would be connected in parallel with the load resistance to measure the power supply voltage. The load resistance is chosen to emulate the load resistances found in the final application, but may be chosen to reach full output capacity to perform stress testing. Figure...

The 14.4V with the engine running is a good indication that the alternator is charging. It should be because I replaced it not too long ago. But doing these sorts of tests with a multimeter can be a bit deceptive. Although the display shows digital numbers and decimals, that in itself ...
