When setting up an instrument, which of the following is not typically necessary to know?

Understanding the rate of flow of the control agent is indeed significant for setting up instrumentation effectively, but it may not be strictly necessary for every instrument setup. The primary focus when configuring instrumentation usually revolves around ensuring that the instrument will function correctly and within the specifications needed for the particular application.

The expected response time of the system is crucial because it helps to determine how quickly the instrument will react to changes in the process, which is vital for maintaining optimal control and ensuring that the system performs as intended under varying conditions.

Calibration standards for instruments are fundamental to ensure accurate measurements. Knowing these standards is essential for maintaining the reliability and precision of the instruments used in any control application, as inaccurate calibration can lead to significant measurement errors and compromised system performance.

Additionally, the manufacturer’s specifications for controls provide critical information about how the instrument should be installed, configured, and operated. These specifications often include data on the operational limits, performance characteristics, and any specific requirements that must be met for the instrument to function correctly.

In summary, while knowing the flow rate of the control agent may be important in some contexts, it is not universally required for every instrument setup, making it the least necessary piece of information in this context.
