(4) Set the Fluke 5500A output to OFF and press Trig/Enter to go to the screen
for storing calibrated data.

(2) Press Trig/Enter the 0.2000 in I measurement window blinks. Set the Fluke
5500A output to 150V/0.2A/60Hz and then begin to output. (To use other
voltage for calibration, use ↑, ↓ to adjust the value in I measurement
window and set the voltage in Fluke 5500A.)
(3) Press Trig/Enter the W measurement window will show the calibrated value
0.2000 (this is the reference) and the PF window will show the message
“done”. The meter will beep concurrently.
