It has a unique feature by which you can adjust long periods by simply adjusting it in the minute mode and then changing the switch to hour mode so you won't have to wait for a long time for measuring the time period. When the timer is changed from minute mode to hour mode, the time duration will be approximately 64 times the time duration measured in minute mode.
In the cyclic mode, the same length of period will be repeated on the 50 / 50 basis duty cycle.
In addition to its continous pre-set adjustment, it has 5 fixed timing periods which can be selected by the position of the jumper. The timing periods are shown on the table below.
