Question 1

Which document defines the acceptable tolerance limits for a piece of test equipment during calibration?

Accepted Answer

Equipment specification sheet

Answer

The equipment specification sheet defines the manufacturer's stated tolerance limits used as the acceptance criteria during calibration.

Question 2

A digital multimeter reads 10.05V when measuring a reference standard of exactly 10.00V. What is the absolute error?

Accepted Answer

0.05V

Answer

Absolute error is the difference between the measured value and the true value: 10.05V − 10.00V = 0.05V.

Question 3

What is the primary purpose of a calibration interval?

Accepted Answer

To ensure equipment accuracy is verified before drift exceeds tolerance

Answer

Calibration intervals are set to ensure instruments are rechecked before accumulated drift can cause measurements to fall outside acceptable tolerance.

Question 4

When a temperature sensor is found out-of-tolerance during calibration, the correct first action is to:

Accepted Answer

Tag it out-of-service and notify affected test areas

Answer

An out-of-tolerance instrument must be removed from service and affected areas notified so prior measurements can be assessed for impact.

Question 5

Which calibration method involves comparing a device under test directly against a higher-accuracy reference standard?

Accepted Answer

Direct comparison calibration

Answer

Direct comparison calibration places the device under test side-by-side with a reference standard to measure the same quantity simultaneously.
