Configuring Alarms in ViewPoint HD
The MD-xxHD power meter has the ability to set alarms for over and under conditions for voltage and
current on any meter channel.
Configuration Input Methods
ViewPoint HD uses dynamic entry for the specification of Alarm settings. Whichever text entry field is
selected becomes the forcing condition and the other related fields are updated by calculation to reflect a
consistent set of conditions.
The text entry fields in grey are “configuration aids” and are NOT retained by
the meter. Only the fields with a black background are stored in the meters memory or in configuration
files.
Nominal Values
Entering alarm thresholds based on “percent of nominal” values is helpful when alarm conditions are
desired to be centered around electrical components or industry standard conditions. For example, an
over current alarm may be set to 80% of an installed circuit breaker to alert when that breaker exceeds
NEC recommendations.
Absolute Values
Entering alarms based on absolute value is a matter of entering the triggering values directly in the
register fields (black background).
