RC oscillation
Use the program to set any of the following four ranges, according to the chart shown below.
0.1 to 1 second
1 to 10 seconds
10 to 60 seconds
1 to 10 minutes
The timing operation can be paused if so specified by the program. therefore, the timers can also
be used as cumulative timers.

SET and TIME UP
External variable resistors can be used to set the time value when the IN/EXT selector is set to
EXT. Use 20 k
W external variable resistors
