Press H, to display power quality data,
including THD, unbalance factor and voltage
eligibility. The screen will scroll to the next display
as you press H each time. It will go back to the
first screen if you press H at the last screen.
The following table shows you how it scrolls:
Note 1: Some patterns do not have these
functions so the key function and display are
invalid.
Note 2: When the meter is set to “2LL”, THD,
unbalance factor and voltage eligibility are based
on the line-to-line voltage; otherwise they are
based on the phase voltage.
Press E to display energy and the real time clock. The screen will scroll to
the next display as you press E each time. It will go back to the first screen if
you press E at the last screen.
The unit of power is kWh and kVARh for reactive power. The running

accuracy of 0.01H and is stored in the nonvolatile memory. It can be reset via
communication port.
The following table shows you how it scrolls:
Note: Patterns without TOU functions will not display the 9th~16th screens.
