SEL

OGIC

 Math Variables

Math calculation result storage locations.

SEL

OGIC

Control Equation

A meter setting that allows you to control a meter function (such as a control 
output) using a logical combination of meter element outputs and fixed logic 
outputs.

Sequencing Timers

Timers designed for sequencing automated operations.

Sequential Events

Recorder

A meter function that stores a record of the date and time of each assertion and 
deassertion of every Meter Word bit in a list that you set in the meter. SER 
provides a useful way to determine the order and timing of events of a meter 
operation.

SER

Sequential Events Recorder or the meter serial port command to request a 
report of the latest sequential events.

Settle/Settling Time

Time required for an input signal to result in an unvarying output signal within 
a specified range.

Stator

The unit that provides the driving torque in a watt-hour meter. It contains a 
voltage coil, one or more current coils, and the necessary steel to provide the 
required magnetic paths. Other names used for stator are element or driving 
element.

Status Failure

A severe out-of-tolerance internal operating condition. The meter issues a 
status failure message and enters a disabled state.

Status Warning

Out-of-tolerance internal operating conditions that do not compromise meter 
protection, yet are beyond expected limits. The meter issues a status warning 
message and continues to operate.

Strong Password

A mix of valid password characters in a eight-character combination that does 
not spell common words in any portion of the password. Valid password 
characters are numbers, upper- and lower-case alphabetic characters, “.” 
(period), and “-” (hyphen).

Telnet

An Internet protocol for exchanging terminal data that connects a computer to 
a network server and allows control of that server and communication with 
other servers on the network.

Terminal

Emulation Software

Software that can be used to send and receive ASCII text messages and files 
via a computer serial port.

Thermal Demand

Thermal demand is a continuous exponentially increasing or decreasing 
accumulation of metered quantities; used in demand metering.

Thermal

Withstand Capability

The capability of equipment to withstand a predetermined temperature value 
for a specified time.

Time Delay on Pickup

The time interval between initiation of a signal at one point and detection of 
the same signal at another point.

Time-of-Use Metering

A metering method that records demand during selected periods of time so 
consumption during different time periods can be billed at different rates.

Total Harmonic

Distortion (THD)

The ratio of the sum of the power of all harmonic frequencies above the 
fundamental frequency to the power of the fundamental frequency. Usually 
expressed as a percentage, large numbers indicate increased distortion.
