Connect 18 VAC to the DUT I/P input. Connect a standard current meter to the DUT outputs 
from L to G. When the power supply and meter are connected, press TEST to activate the 
calibration. Read the measurement from your standard and enter it using the numeric keypad.   
You may now store the new calibration number by pressing the ENTER key or escape by 
pressing the EXIT key or the RESET button.
