Today one of the most useful tools for trouble shooting electrical issues is the DVOM-Digital Volt Ohm Meter. This versatile device can look into circuits and diagnose trouble. It is capable of measuring AC/DC Voltages, Resistance in Ohms, Amperage, and other functions based on the model owned.
This will focus on DC voltage measurements and safety. Look at circuit or device to be tested. Determine voltage to be tested.
Turn the meter on and set it for DC Volts, and set the range above what is expect in this test. (Here I chose a 1.5 volt battery. And I chose 20 Volt scale which is the lowest scale above the 1.5 Volts being measured ) Inspect probes for damage, look for bare or cracked or wires.
Look for cracked probes. If damage is found, dispose of meter lead. UNDER NO CIRCUMSTANCE DO YOU USE DAMAGED LEADS.
Grasp probes behind the finger protector (seen in picture)DO NOT GRASP PAST FINGER PROTECTOR, CAN BE FATAL! More.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
