Answer :
In the context of a manifold set, which is a tool used in refrigeration and air conditioning systems, the high-side gauge measures the pressure on the high-pressure side of the system. This is typically used to assess the pressure of the refrigerant after it has been compressed by the compressor and before it enters the condenser.
The correct pressure range for a high-side gauge on a manifold set is from [tex]0 \text{ psig}[/tex] to [tex]500 \text{ psig}[/tex]. Therefore, the correct answer is:
C. 0 psig to 500 psig.
Explanation:
Manifold Sets: These are tools used by technicians to check the pressure of refrigerants in HVAC (Heating, Ventilation, and Air Conditioning) systems. They consist of hoses, gauges, and a manifold block that allow the technician to measure and control the flow of refrigerant.
High-Side Gauge: Specifically measures the high-pressure side of the system. After refrigerant is compressed, the pressure increases significantly, which is why the high-side gauge needs to accommodate higher pressures compared to the low-side gauge.
Pressure Ranges: Gauges are designed to cover specific pressure ranges to ensure safety and accuracy. The high-side gauge must cover a wide range because compressor pressures can vary significantly under different conditions.
Practical Usage: Maintenance of the correct pressure levels is crucial for the efficient operation of HVAC systems. If pressures are not within expected ranges, it may indicate problems like refrigerant overcharge or obstructions in the system, requiring immediate attention by a qualified technician.
Understanding the correct use and range of the manifold set gauges is key for technicians engaged in HVAC system maintenance and repair. It ensures safety and proper functioning of the systems.

When dealing with a manifold set in refrigeration or air conditioning systems, the pressure range of the gauges is crucial for proper system diagnostics and servicing. The manifold set typically includes two main gauges: the high-side (or high-pressure) gauge and the low-side (or low-pressure) gauge.
The high-side gauge is designed to measure the pressure in the high-pressure side of the system. Commonly, the high-side gauge will have a range of 0 psig (pounds per square inch gauge) to 500 psig. This range allows for the measurement of pressures that are generally expected under normal operating conditions of most air conditioning and refrigeration systems.
Given the options provided in the question:
A. [tex]30'' \text{ Hg to } 300 \text{ psig}[/tex]
B. [tex]0 \text{ psig to } 300 \text{ psig}[/tex]
C. [tex]0 \text{ psig to } 500 \text{ psig}[/tex]
The correct answer is C. [tex]0 \text{ psig to } 500 \text{ psig}[/tex].
This selection is based on the typical pressure range expected for operating and testing high-pressure sides of HVAC systems. Understanding this range is important for ensuring that the system is functioning correctly and safely, as readings outside the normal range could indicate potential issues such as overcharging or leaks.
