Using Periodic Timers
The EM920 has 4 programmable interval timers that are
normally used for periodic recording and triggering operations
on a time basis through the Control Setpoints.
Whenever a programmed timer interval is expired, the timer
generates an internal event that can trigger any setpoint (see
Using Control Setpoints ). The programmable time interval
can be from 1 cycle and up to 24 hours. Though it is defined
in 0.001-second units, the actual value will be rounded in the
meter to a nearest bigger 1/2 cycle multiple.
To configure interval timers, select General Setup from the
Meter Setup menu, and then click on the Periodic Timers tab.
To run a periodic timer, specify a non-zero time period.
To stop a timer, set the time period to zero.
