Page 7: Tmx3Rh Method
TMX3RH METHOD The TMX3RH is a high accuracy silicon device for the measurement of relative humidity and dry bulb temperature. Both sensors are integrated in one small silicon chip, factory calibrated and conditioned to give accurate and fast response. The TM360A uses this accurate data to compute the wet bulb and the dew point temperatures using the latest software algorithms. -
Page 8: Psychrometric Chart
PSYCHROMETRIC CHART Psychrometry is the science which studies the properties of moist air. A psychrometric chart graphically illustrates the relationship between air temperature and relative humidity as well as other properties. Air Temperature is a measure of the heat content of air. Three different temperature measurements are used in the psychrometric chart. -

Page 11: Technician Operating Tips
TECHNICIAN OPERATING TIPS Experience has shown that accurate temperature readings can be affected by several factors. Listed below are some of the conditions you may encounter when performing temperature drop tests. The pressure that you apply to a temperature probe can affect the reading by as much as 20°F (-6°C). -

CONDENSER FLOW CHART A Measure condenser inlet and outlet temperature within 4” of condenser of the condenser. Temperature drop (difference) should be between 20°F and 50°F (-6°C and 10°C) in a properly performing system. Between 20°F and 50°F Less than 20°F (-6°C) More than 50°F (10°C) (-6°C and 10°C) CHECK CONDENSER FOR AIR... -
Page 18: Air Efficiency Flow Chart B
AIR EFFICIENCY FLOW CHART B Measure ambient air temperature 16-18” in front of the condenser. Measure air temperature of the AC duct closest to the evaporator using the vent probe. The temperature difference between ambient and duct air should be approximately 30°F (-1°C) in a properly performing system. -
Page 19: Evaporator Flow Chart C
EVAPORATOR FLOW CHART C Measure the evaporator inlet and outlet temperatures as close to the evaporator core as possible. The ideal temperature difference between the inlet and outlet is 0°F (-18°C). The acceptable temperature range for the outlet tube is from 5°F (-15°C) colder to 5°F (-15°C) warmer than the inlet tube. -
