Information
The Models 646-1 and 646-3 are portable instruments designed
to monitor the quality of ac power being supplied to
sensitive electronic equipment. These units operate by
continually measuring the voltages at their inputs, and then
reporting any unusual occurrences (such as drop-outs and
high voltages which sometimes occur during severe
thunderstorms).
1.3.1 Disturbance Reporting
A disturbance is reported whenever the measured value falls
outside "normal" (outside the programmable high or low limit).
For example: A Series 646 may be programmed to report
whenever the line voltage falls below 105 V ac or rises
above 125 V ac, Each time a disturbance is detected, a
detailed printout describing the event is generated. This
printout includes the time, date, amplitude, and duration of
the disturbance.
