1) CIRCUIT CONFIGURATIONS AND TYPICAL POWER MEASUREMENT APPLICATIONS
NOTE: With a 3P4W load, Transducer connections are line-to-neutral.
2) STANDARD WATT / VAR CALIBRATION RANGES
3) DETERMINING CALIBRATING WATTS FOR A WATT OR VAR TRANSDUCER

and primary Watts/VARs relative to desired output. Non-standard ranges are available as an option.
When PT and CT secondary inputs are specified the calibrating watts can be determined as follows:
Example #1 - 3P3W, 2 element with 0-1mA output for 0-25KW input, PT= 480 : 120V, CT = 30 : 5A
Example #2 - 3P3W, 2 element with 4-20mA output for 0-20KW input, PT = 480 : 120V, CT = 30 : 5A
