4.9 Timers Setup Menu

This menu allows you to access the two interval timers provided by the
PM172EH which can trigger setpoints on a user-defined time interval
basis. This is useful for continuous data logging at specified time intervals
in order to produce trend and load profile graphs.
Each timer has a time interval range up to 9999 seconds at a one-second
resolution and runs independently. The timer accuracy is about
±
0.05 sec.
To use a timer as the trigger for a setpoint, simply select one of the timers
as a trigger when defining the setpoint, and then specify for the selected
timer a non-zero time interval at which you want the periodic action (for
example, a data log) to be made. To stop a timer, set the time interval to
zero. Each timer can be used to trigger multiple setpoints, for example, if
you need multiple data logs at the same time.
