After selecting a monitoring mode, press the Trigger Limits tab or press

Next. The Limits screen will vary according to the selected monitoring

mode.

Trigger Limits for all Monitoring Modes Except Voltage Compliance

(EN50160):

The Xplorer allows you to set the limits for the following triggers:

 Set RMS Limits – use to review/modify limits for rms variation

as well as set the amount of rms value (in cycles) to record

before and after the trigger cycle.

Dranetz instruments label rms voltage or current variations as

either sags (voltage or current decreases below low limit) or

swells (voltage or current increases above high limit) as per

IEEE 1159. Voltage disturbances which are shorter in duration

than typical sags and swells (which are usually 1/4 cycle or

longer) are classified as transients.
