4. Full Scale Calibration for Current Measurement Range:
Low Current Shunt:
a. 0.01 Range Calibration:
(1) Connect the I+ and I- output of Fluke 5500A to the I+ and I- on 66202 rear
panel respectively. Then the screen will show as below (the V measurement
window blinks):

(2) Press Trig/Enter the 10.00 in I measurement window blinks. Set the Fluke
5500A output to 150V/10mA/60Hz and then press OPR to begin 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
10.01 (this is the reference) and the PF window will show the message “done”.
The meter will beep concurrently.
