【Instructions】
Time range setting:
When the selector switch is placed in the 30 position, it means 0-30 is adjustable
When the selector switch is placed in the 300 position, it means 0-300 is adjustable
Adjustment of time value:
Turn the adjustable resistor counterclockwise in the - direction to decrease the time, and turn it clockwise in the + direction to increase the time
Time unit setting:
When the selector switch is in the Sec position, the unit is: seconds
When the selector switch is in the Min position, the unit is: minutes
Example:
Request a 50-minute delay:
1. The scope is placed at the 300 position
2. The time unit is placed in the Min position
3. Adjust the adjustable resistance to the 50 position, and the full adjustment is 300, so the adjustment to 1/5 is 50.
Note: The adjustment of the potentiometer can also be quickly adjusted with the voltage gear of the multimeter. For example, the range of 30 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
