Instructions
Time range setting:
When the selector switch is in the 30 position, it means that 0-30 is adjustable
When the selector switch is in the 300 position, it means that 0-300 is adjustable
Adjustment of the time value:
The adjustable resistor rotates counterclockwise in the direction of - sign to decrease the time, and turns clockwise in the direction of + sign to increase the time
Time unit setting:
When the selector switch is in the Sec position, the unit is: second
When the selector switch is in the Min position, the unit is: minute
Example:
Request a 50 minute delay:
1. Set the range to 300
2. The time unit is placed in the Min position
3. The adjustable resistance is adjusted to 50 position, and the full adjustment is 300, so it is 50 when it is adjusted to 1/5.
Note: The adjustment of the potentiometer can also be quickly adjusted with the multimeter voltage file. For example, if the range is 30, it needs to be adjusted to 12, then the voltage can be adjusted to 2.
t=Ut/5*30=2.0V / 5.0V * 30 =12
Ut is the voltage measured by the multimeter, 30 is the range selected by the selector switch, and it can also be selected to 300

1. The real color of the item may be slightly different from the pictures shown on website caused by many factors such as brightness of your monitor and light brightness.
2. Please allow slight manual measurement deviation for the data.
