Setting the EMF Limits
The setting of the EMF limits must be optimized over one or two maintenance
cycles. Initially, no EMF limit should be set. When instrument performance
indicates maintenance is necessary, take note of the values displayed by lamp
counters. Enter these values (or values slightly less than the displayed values)
as EMF limits, and then reset the EMF counters to zero. The next time the EMF
counters exceed the new EMF limits, the EMF flag will be displayed, providing
a reminder that maintenance needs to be scheduled.
