•RMS triggers occur when any

one of the measured quantities

crosses the high or low limit for a

period of at least one rms sample

point (which are taken twice per

cycle with a one cycle sliding

integration window)

•Disturbance End = the cycle

when all triggered channels

return within limits for a minimum

duration of cycles specified in

range to end event. Until then,

any subsequent excursions

beyond the thresholds are

considered part of the original

disturbance. To minimize the

number of triggers recorded for a

sequence of closely spaced

disturbances, hysteresis is

employed in both voltage and

time for the begin-event and end-

event thresholds

•Press: RMS Variation Limit

Wizard Setup: RMS Variation Limits

•If applicable, Press: Group

A B C to simplify setup

•Press the threshold

parameter (High, Low, Very

Low) to change, enable or

disable threshold values

•High limits must be at least

.1 higher than Low limits, or

the entered value will not

be accepted.

•Press: % of Nominal to use

percentages instead of

volts

•Press the other tabs to set

other channels

•Press: Amps
