Function
There are two modes to choose from (n):
Mode 0: Calculate the corresponding humidity by wet bulb temperature and dry bulb temperature.
Mode 1: Calculate the corresponding wet bulb temperature by dry bulb temperature and humidity.
The conversion process formula is as follows:
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:
Precautions
·The wet bulb temperature is not greater than the dry bulb temperature. When they are the same, the humidity reaches the maximum value 100%.
·The unit of dry and wet bulb temperature is (oC).
·The general value range of dry bulb is between 0~100oC, and the command does not judge its range, so pay special attention when using this command.
Error code
| Error code | Content |
|---|---|
| 4084H | When the value specified in (n) exceeds the following range. 0 to 1 |
| The value specified in (d1) exceeds the following range. 0 to 100 | |
| A negative value is specified in (s). | |
| A negative value is specified in (d2). | |
| 4085H | The output result of (d1)(s)(d2)(n) in the read application command exceeds the device range. |
| 4086H | The output result of the write application command (d1) and (d2) exceeds the device range. |
