| 95 | Function | ||
| 96 | |||
| 97 | There are two modes to choose from (n): | ||
| 98 | |||
| 99 | Mode 0: Calculate the corresponding humidity by wet bulb temperature and dry bulb temperature. | ||
| 100 | |||
| 101 | Mode 1: Calculate the corresponding wet bulb temperature by dry bulb temperature and humidity. | ||
| 102 | |||
| 103 | The conversion process formula is as follows: | ||
| 104 | |||
| 105 | Assuming that the wet bulb temperature is A, the dry bulb temperature is B, and the corresponding current humidity is C, which meet the following conditions: | ||

| 109 | |||
| 110 | |||
| 111 | Precautions | ||
| 112 | |||
| 113 | ·The wet bulb temperature is not greater than the dry bulb temperature. When they are the same, the humidity reaches the maximum value 100%. | ||
| 114 | |||
| 115 | ·The unit of dry and wet bulb temperature is (^^o^^C). | ||
| 116 | |||
| 117 | ·The general value range of dry bulb is between 0~~100^^o^^C, and the command does not judge its range, so pay special attention when using this command. | ||
