Calibration
Pwer Meter Calibration
Traceability of wide-bandwidth power meter
Calibration method for the working standard
- Voltage calibration
- Current calibration
- Phase angle measurement of the capacitor
- Preparing some capacitors each frequency (50/ 60/ 400/ 1k/ 2k/ 5k / 10k/ 20k/ 50k/ 100k/ 200k/ 500kHz)
- Measuring admittance (Conductance-G and susceptance-X) of the capacitor using precision LCR meter
- Calculating the phase angle of the capacitor
- Power calibration at PF=0
(It measures Internal phase difference between voltage and current input circuit.)
- Power calibration at PF=1
Calibration Method for working standard at PF=0
