CHAPTER 5: OVERVIEW ACCESSING %THD FUNCTIONS
EPM 5300 SERIES ADVANCED POWER METERS – INSTRUCTION MANUAL 5–33
5.3 Accessing %THD Functions
Harmonic Measurement readings are available on the EPM 5300P meter. The EPM 5300P
displays 6 parameters of total harmonic distortion. It measures harmonic waveforms and
%THD for voltage phases A-N, B-N and C-N, and current phases A, B and C. Measurement
capability reaches the 31
st
harmonic order. All readings are faceplate accessible.
To access %THD:
Step 1:
a. To access %THD values for a voltage or current
phase press VOLTS/THD (or AMPS/THD) twice.
The display blanks and indicates the %THD value
momentarily.
