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
