Yes. This is usually an indication that either its current coil or its voltage coil has been wired incorrectly.

Why would you get a negative voltage reading?
Because the meter is connected backwards
What is the minimum watt of a light bulb for night reading?
40 watt light bulb. This is obvious. Go do an experiment. -_-
What if you have a negative kvar reading?
A negative KVAR reading can be eliminated by adding an inductor to the circuit.
Why wattmeter measure the reactive power?
A watt meter will measure active power, not reactive power.
Why watt-meter is required to measure real power delivered to a purely resistive load?
A wattmeter (not 'watt-meter') will always measure the true power of a load, regardles of whether that load is purely resistive or not. This is because a wattmeter effectively measures the in-phase component of the load current.
Does watt meter reading go negative?
Yes!
Why would you get a negative voltage reading?
Because the meter is connected backwards
How many voltmeter and ammeter are in dc watt meter?
There is no volt meter or amp meter in a DC watt meter.
What will happen to dc signal if positive probe connected to negative terminal and negative probe connected to positive of the dc supply?
If you are referring to using a volt meter then you will just get a negative reading on most modern digital meters. If you are using an old analogue meter you may get no reading.
Why you reset the zero point on the watt meter?
So that the result that you find on the watt meter after resetting it will be accurate
When is it important to make sure to match the polarity of the meter leads to the polarity of the circuit being tested?
This is important when meter cannot display negative values, e.g. it is analogous meter with scale. Most digital meters can display negative values. P.S. I am amateur in elecrtonics.
What is the relation between Newton meter and watt?
1 Watt = 1 Joule / Second = 1 Newton-meter / Second.
What is a meter socket?
The electrical power that you use from the utility company has to be metered. This is done with a plug in watt meter. The meter socket is what holds the electrical watt meter. It is this meter that the meter reader reads to give you your monthly billing for the electricity that you used.
How do you measure polarity?
In a DC circuit, just connect your meter across the source or electrical bus. The meter, because it is one of the newer digital ones, will work regardless of which way the leads are connected. If the leads are plugged into the meter correctly, the investigator need only look at the sign associated with the reading on the meter and the position of the leads. If the reading on the meter is "13.6 V" on a DC setting, then the red lead is connected to the positive side or negative rail, and the black to the negative side or negative rail. Conversely, if the reading is "-13.6 V" on a DC setting, the red lead is on the negative side or negative rail, and the black lead is on the positive side or positive rail. The DMM is a wonderful innovation and will allow someone making measurements to not have to worry about which way to connect the leads - as long as that someone pays attention to the sign displayed with the voltage reading.
What are the types of electrodynamometer?
power meter,power factor meter, frequency meter, volt meter ,watt meter ,voltage ampere meter,
How do you interchange connection of watt meter in 3 phase induction motor loading when it shows negative deflection?
interchange connections of c and v i.e pressure coil
How do you provide a meter reading?
where do you go on your website to notify you of meter reading
