2. Chapter 4, Question 5.
List seven factors in making a good measurement: Error, validity, reliability, repeatability, accuracy, precision, resolution.

3. Chapter 4, Question 18. List several types of characteristic errors.
zero offset.
gain
processing
linearity
hysteresis
repeatability
resolution.

4. Chapter 4, Question 19.
For digital systems, overall error must include the quantization error caused by the digital nature of the circuits.

5. Chapter 4, Question 21.
A voltage measurement error is caused by the integration time window of a digital voltmeter. This is a dynamic error.

6. Chapter 4, Question 22.
If a low-impedance voltmeter is inserted into a high-resistance dc circuit, a instrument insertion error is created.
