(Phase Imbalance Switch)
Syncrolite ballast taps may be set to accommodate a variety of voltages. To confirm that the
tap settings are correct, meter amperage and voltage and calculate wattage (A x V=W).
Amperage may be determined by use of an amp probe clamped around the positive of the
lamphead cable lead from the ballast.
