k is the order of the harmonic;
n is the maximum order of the harmonic(For LT-101A, it is 50).
Notes: The range of input harmonic signal is 10% ~ 100% F.S..
5.1.3 Harmonic analysis
"ANALYZE": Press "ANALYZE", the indictor will be flickering and the instrument
is under the state of harmonic analyze, press again to exit.
"RMS": Press "RMS" to display the RMS or relative value of harmonic in different
times.

5.2 Output characteristic test at steady state
5.2.1 Measurement parameters
The output electric parameters can be tested under stable state including RMS values
of voltage and current, frequency, active power, and power factor of power supply.
5.2.2 Window display
The output voltage(V) or frequency(Hz) can be displayed in Window E according to
different selection, and the output current(A) of LED driver can be displayed in
window F. In addition, the active power(W) or power factor(PF) can be displayed in
window G according to different selection and the efficiency of power supply can be
displayed in window H.
5.2.3 Steady-state testing
Press "RUNNING" to switch into the steady state from output start-up testing state.
