How to use:
Adjust the time counterclockwise to decrease, and adjust it clockwise to increase. The resistance range is about 0~5Ku03a9. When T1 is adjusted to 0u03a9, the relay does not work.nFormula: T1, T2 time (seconds or minutes) = voltage value (MV) /32.8095nFor example: the measured voltage value is 273MV. If the working time unit is seconds, the timer time is about: 237/32.8=7.2 seconds;nIf the working time unit is minutes, the timer time is about: 237/38.8=7.2 minutesnFor example: the measured voltage value is 1.37V. If the working time unit is seconds, the timer time is about: 1370/32.8=41.8 seconds;nIf the working time unit is minutes, the timer time is about: 1370/32. 8=41.8 minutes
