transmitter can record the offset value under temperature of 45
℃
.
After these two steps calibration, the
output value will be the correct one.
Two steps for humidity linear calibration setting:
z
Entering into humidity calibration mode (press MENU and number 4), press OK to enter humidity
range 75% calibration point. That is the current humidity should be 75%. Transmitter LCD will display
two-line values after the humidity is stable (about 30mins or more). The first line displays the testing
humidity U1; the second line displays 75%. Now you can choose UP and DOWN keys to calibrate the
U1 to 75% and click OK key to confirm so that the transmitter can record the offset value under
humidity of 75%.
z
Then entering into humidity range 33% calibration point, that is the current environment humidity
should be 33%. Transmitter LCD will display two-line values after the humidity is stable (about 30mins
or more). The first line displays the testing humidity U2; the second line displays 33%. Now you can
choose UP and DOWN keys to calibrate the U2 to 33% and click OK key to confirm so that the
transmitter can record the offset value under humidity of 33%. After these two steps calibration, the
output value will be the correct one. Now you can back to the normal working mode and both of the
value is correct.
