The pressure gauge is a good example of a deflection-type instrument, where the value of the quantity being measured is displayed in terms of the amount of movement of a pointer. An alternative type of pressure gauge is the dead-weight gauge which is a null-type instrument. Here, weights are put on top of the piston until the downward force balances the fluid pressure. Weights are added until the piston reaches a datum level, known as the null point. Pressure measurement is made in terms of the value of the weights needed to reach this null position.
The accuracy of these two instruments depends on different things. For the first one it depends on the linearity and calibration of the spring, whilst for the second it relies on the calibration of the weights. As calibration of weights is much easier than careful choice and calibration of a linear-characteristic spring, this means that the second type of instrument will normally be the more accurate. This is in accordance with the general rule that null-type instruments are more accurate than deflection types.

What Difference between null type and deflection type instrument?
Null type instruments require balancing the unknown quantity with a known quantity to obtain a measurement, while deflection type instruments measure the unknown quantity based on the amount of deflection of a pointer or needle. Null type instruments are more accurate but require more setup, while deflection type instruments are simpler to use but may have less precision.
What is difference between null type and deflection type instruments?
Null type instruments require a null balance point to be achieved for accurate measurement, while deflection type instruments measure the quantity directly as a deflection on a scale. Null type instruments are more accurate but require more intricate adjustments, while deflection type instruments are simpler to use but may have lower accuracy.
What type is the Pokemon Type Null?
Type: Null is a Normal type, and it was introduced in the Generation 7 games, Pokemon Sun and Pokemon Moon. The evolution path for Type: Null is Type: Null (Normal) >>> Silvally (Normal). However, the Silvally evolution can change type depending on what is placed in its RKS system drive.
What are the advantages and disadvantages of the VOM as compared to the electrical measuring instrument?
As a VOM (volt-ohm meter) is one type of electrical measuring instrument, it is unclear how to answer this question. It is almost as if you had asked "What are the advantages and disadvantages of the banana as compared to the edible plant part?"
What is weston galvanometer?
A weston galvanometer is a type of sensitive instrument used to detect and measure small electric currents. It uses a moving coil suspended in a magnetic field to deflect in response to the current passing through it. This deflection is then used to indicate the strength of the current.

What is an alpha error?
An alpha error is another name in statistics for a type I error, rejecting the null hypothesis when the null hypothesis is true.
What type of instrument can detect the presence of an electrical charge?
a gold leaf electroscope. if initially charged negatively, the deflection of the leaf with respect to the electroscope is increased if a negatively charged object approaches the electroscope. conversely if a positively charged object approaches, the deflection is reduced. the angle of deflection is proportional to the magnitude of the charge.

What is the difference between a Type I error and a Type II error in hypothesis testing?
In hypothesis testing, a Type I error occurs when a true null hypothesis is incorrectly rejected, while a Type II error occurs when a false null hypothesis is not rejected.
