1. To complete the charts: Mark the delivery temperature along the vertical line. Mark the intake temperature (ambient air temperature) along the bottom line. Draw a line straight up from the air temperature to the humidity. Mark a point 10 % above and 10 % below the humidity level. From each point, draw a horizontal line across the delivery temperature. The delivery temperature should fall between the two lines. Complete the low-side pressure test and high-side pressure test in the same way. Any measurements outside the line may indicate the need for further inspection.
   Example | Intake temperature (dry): | 30 °C (86 °F) Humidity level 70 %
   | Intake temperature (wet): | 25.5 °C (77.9 °F)
   | Intake pressure: | 314 kPa (3.2 kgf/cm 2 ) (45.5 psi)
   | Delivery temperature: | 16.6 °C (61.9 °F)
   | Delivery pressure: | 1,618 kPa (16.5 kgf/cm 2 ) (234.7 psi)
   Results: | Within normal range
