Please note that without the help of a pickup, if the operator signals the start or the
end of a test with the magnet too early or too late, the number of disk revolutions
(whole number, no fractions) may not be accurate and will affect the test’s precision.
Tracking Test is similar to Manual Test except that the socket counts the number of
revolutions and displays them on your wireless device. The count is based on the
selected Kh for the meter and the cumulative watthours recorded by the MT-1/WT3,
not the physical count of the disk revolutions. A magnet can be used to start and end
the test.
kW Demand Test allows the operator to perform a kW demand test. The test is
calculated using this formula:
kW = kWh x 60/T
Where T = Demand interval length in minutes
Note: With solid-state metering, conducting energy and demand tests may be
considered redundant since they are both results of the same measurement.
Set up the meter for a kW demand test following the manufacturer's instructions.
Please note that instructions for conducting kW demand tests will vary by
manufacturer, as per their respective technical guides.
Line Monitor Test analyzes the input voltage to statistically determine the line
voltage, frequency fluctuations and its harmonic content (THD) up to the 32nd order.
KYZ Test is used to verify the KYZ or KY meter’s output pulses.
