When testing for electrolysis in the cooling system the digital volt-ohmmeter (DVOM) reading should not exceed?

What tool can be used to test for electrical conductivity?
The easiest way is to use an Ohmmeter. This function is usually built into most multimeter that can be bought at any hardware store. An Ohmmeter measures the electrical resistance of a material. The lower the number the more conductive that material is. If the Ohm reading is above the maximum reading on the meter then their is infinite resistance which means that the material is not a conductor of electricity.
What are the problems relating the electric meter reading?
Dogs.
How much current flows in a circuit with an open circuit?
None.AnswerIt depends! A capacitor is an open circuit, yet a.c. current flows quite readily. And d.c. current will flow for a very short period of time.
How would a three phase meter reading compare to three single phase meters connected to the same service?
The reading on the 3-ph meter would equal the sum of the three separate readings on the single-phase meters. The neutral sides of the single phase meters do not need to be connected to the neutral wire as long as they are connected together.

What reverse resistance reading should diodes have when under test with an ohmmeter?
Reverse resistance should be infinite.

When using an ohmmeter what should be the results for an NPN transistor?
When the positive lead is at point "P" which is the base and the negative lead is at either of points "N" which is either the emitter or the collector, then the ohmmeter should have a very low reading or reads short circuit. Also, when the negative lead is at point "P" and the positive lead is at either points "N", then the ohmmeter should have an infinite reading when the meg ohm range.
What value will appear on ohmmeter when we will check 100 uh microhenry inductor?
The reading will be very close to zero ohms.
How can the cathode end of a zener diode be determinded using an ohmmeter?
Hard to do. If your Ohmmeter battery is just 1-1/2 volts, then you simply put the test leads on the diode one way, then the other way. The way that show a meter reading will have the black lead on the 'cathode', if you assume, as most do, that electrons are issued from the " - " or 'minus' side of the battery. BUT . . . if your Ohmmeter voltage is above the zener's trigger voltage, then you will get a reading both ways.
What is the ohmmeter reading for open circuit?
The capacitor has no resistance which your direct current ohm meter can show.
How do you connect an ohmmeter in series or paallel?
A: To read ohms you will use it by reading in parallel and without any external voltage applied

What happen ohmmeter hook up to a live circuit?
Depending on the voltage, make sure to be safe, but I don't think that it is too bad, although it does depend on the circuit
A zero reading on an ohmmeter means the circuit or component is open is this true or false?
This is false. A zero reading is what you get when you press the probes of themeter together with nothing between them, to make sure the meter is working.That's about as closed as the circuit under test can get.
What ohms setting do you use on a meter for 240v electric heater?
Whenever you use an ohmmeter, you must first ensure that the device you want to test is disconnected from the supply. So the fact that your heater is rated at 240 V is irrelevant to this question. The heater must be disconnected from the supply BEFORE you contemplate measuring its resistance. Which 'ohms setting' to use is then simply determined by whichever setting gives you the best reading. For an analogue ohmmeter, this is whichever setting results in the pointer being towards the lower-resistance end of the scale.
