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.

How can you get 240V single phase power from a 240V 3 phase service Can you just connect to two poles of the 240V 3 phase service?
I'm sure this isn't what you want to hear, but you probably need to ask an electrician familiar with your service and what you want to connect. As a general answer, you can connect a 240v line to line resistive load like an electric water heater to any 240v source. If you also need the 240v to have 120v line to neutral, like a 240v electric stove that contains a 120v clock and oven light, then its possible if the 3 phase power is connected in a "high delta" configuration, and you connect to the correct leads. If you have a high delta service and want to ignore the 3-phase power service and wire most or all of the loads in the building as a single phase load, the utility may have to be consulted.
Would a 30A 240V circuit breaker be too large to safely support a either a 20A or 23A 240V bandsaw?
Yes it will operate it fine.
What would the control voltage be for a transformer marked 240v 24vac?
A control transformer marked 240V - 24Vac would have a control voltage of 24 volts.
Will a 240v 3 phase welder run better than 240v 1 phase?
Yes, because you will be able to maintain current flow between phases.
You are building a new house and trying to decide between 120v and 240v which is better More practical?
In the US, both 120v and 240v will be needed for your home, as different appliances need different voltages. Your TV needs 120V, while your electric dryer and stove will need a 120V/240V supply. If you have an electric water heater, or central AC unit, they will need a 240V supply.

What voltage is needed for electric ovens?
240V
Why wont your central air start and your lights and electronics keep flickering?
It is very possible that you have lost 1 phase to your home. This means that one of the 120 volt lines ( you have 2) coming into your home is out. This could be at the meter or at the pole/ground transformer. Some of the appliances and lights in your home will work and some will not. An AC unit requires 240v to operate. So does and Electric dryer, heat pump, electric water heater, and some electric baseboard heat. You should call an electrician or your local electric company to have the issue fixed.
Can you use one wire from the panel with 240v on it to wire a 240v water heater?
In North America it takes two "hot" wires to obtain 240 volts.
IS there an adapter for a 240V heater that will allow you to plug it into two 110V outlets?
No. Sounds like a fairly hazardous thing to try as well. If it's to use a heater in the US, then buy a US heater at a lower cost than any adaptor that might do the job for you. If it's to use on a UK building site that has 110V but doesn't have 240V, it breaks all the rules because you end up with 240V where you shouldn't.
What is the number of AMPS for a 240V 2400 watt water heater?
Watts = Amps x Volts for a resistive load like a water heater.

How do you change a heater from 120 volts 3a to 240 volts 1.5 a?
the simplest solution is by connecting two 120v 3amps heater in series , the same can be used directly on 240v. However the current drawn will still be 3 amps & Not 1.5 amps. The heater output power will be double that of a single heater running on 120v. ( or equvalent to two heaters operating on 120v. supply ) A more expensive method is to use a stepdown transformer which can be powered on 240v & connect the heater on the transformer 120v side. this method will consume approx. 1.5 amps from the 240v supply.
