■ Input Range

How To Determine Var Range:

Calibration Range [var] = Measuring Range ÷ ((VT Ratio) ×

(CT Ratio))

Check that the required calibration range is within the

available range in the table. Specify this range when

ordering.

[example]

3-phase / 3-wire, measuring range 75 kvar, VT 220 / 110 V,

CT 250 / 5 A
