When measuring an unknown value of voltage the meter should be initially set to?

With an unknown voltage you should start out with the highest voltage setting on the meter. Doing this reduces the risk of "pegging" out the needle on an analog gauge or overloading the input of a DMM. Most DMM's are auto-ranging though.

When measuring an unknown voltage with a multitester or analog VOM you should first?
Go to highest scale on AC range
Should you increase voltage or resistance to increase flow in a circuit?
To increase (current) flow in a circuit you increase voltage (or decrease resistance). Ohm's Law: Current = Voltage divided by resistance
Three good reasons why you should go to Lake Lousie?

What is the influence of gate voltage on drain source breakdown voltage in mos transistors?
Drain-to-source breakdown voltage (BVdss) should not change appreciably until the gate-to-source voltage (Vgs) approaches the device's threshold voltage (Vth). In that case, the drain to source voltage becomes the product of the drain-to-source current (Ids) and the device's on-state resistance (Rds-on) at the given Vgs.
What should you do if your epson printer is running with some kinds of unknown technical issues?
You should take the printer to a technician.
When measuring an unknown voltage with a multitester or analog VOM you should first?
Go to highest scale on AC range
In the unknown of measuring the voltage what should be the setting of VOM selector?
Use the highest available voltage setting. One should know the system voltage before attempting to measure, other wise it may lead to accidents.
When measuring voltage the probes should be connected in?
can some one please tell me when measuring voltage the probes should be connected to sequence or series?
When measuring an unknown voltage with an analog VOM you should first?
For any value turn the multimeter to the highest scale in the value that you are measuring. By doing this you will not overload the meter by using a lower scale to measure a higher value.
When measuring resistance what should done to the supply voltage?
supply should be off
If you discover a UXO measuring 24 inches in diameter how far should personnel initially evacuate?
1500
What range should you set the voltmeter prior to taking a voltage measurement?
Make a guess of what the voltage will be and set the range accordingly. If needed, change the range after measuring the voltage, to get a better reading.
When measuring voltage how should test probes be connected?
First connect the positive terminal of the voltage line to positive terminal of multimeter and negative to negative terminal of multimeter. Select voltage in multimeter and measure the voltage
If you discover a unexplosive ordiance measuring 24 inches in diameter how far should personnel initially evacuate?
1500 feet
What range should the voltmeter be set prior to taking a voltage measurement?
If the voltage is completely unknown, a voltmeter should be set to the maximum range first, then stepped down to an accurate level.
Do you unplug before measuring resistance?
Yes. Measuring resistance involves imposing a small current through a device and measuring the voltage drop. If there were any other source of voltage, the reading would be in error. You could also damage the ohmmeter if there were an external voltage source. You should also take the device out of circuit before measuring it, so as to not bias the results by the resistance of other devices in the circuit. It all depends on the situation, for which you are responsible for evaluating before you start.
When measuring a large current flow should you use a shunt with zero resistance?
It is not a shunt with zero resistance. It is very small, but it is not zero. The large current develops a small voltage across the small resistance. Measuring that small voltage gives you a proportional measurement of the current.
