A manifold gauge is used To gauge air conditioning method impulse.
An air conditioning manifold gauge allot is a chambered Slogan designed to domination the flow of energy and gases. AC gauges are used for measuring the power in a closed-system air conditioning unit to assess or troubleshoot it. This Slogan can be used to transfer refrigerant to and purge AC systems. Scan the suction pressure on the gauges by locating the compound gauge, finding the vigour and vacuum measurements and reading the suction coercion.
Instructions
1. Catch the compound gauge. There are two gauges on a manifold locate -- one blooming and one woebegone. The compound or low impulse gauge is the gloomy one on the left side. There are distinct circles of numbers within this gauge.
2. Contemplate for the vigour and vacuum measurements by finding the outer circle of numbers on the compound gauge. This circle measures pressure and vacuum. Do not pay attention to the inner circles because they measure temperature. The pressure and vacuum scale will be partially black and partially red.
The black numbers measure pressure and they are in pounds per square inch (PSIG). The red numbers measure the pressure below atmospheric pressure. The vacuum or suction pressure part of the gauge goes from 0 to 30 HG or inches of mercury.3. Read the suction pressure. Look for the red numbers on the outer measurement circle.
4. Know what a suction pressure reading means. Suction pressure is when the low pressure reading on the gauge is so low that it dips below atmospheric pressure. This could mean that the air conditioning system has a defective expansion valve. The expansion valve controls the flow of refrigerant into the evaporator of an air conditioning system.
