32, the control will operate in SECONDARY PRESET-RANGE COMPENSATION
mode with Rogowski Coil. When the control operates in this COMPENSATION mode, the
value of PERCENT CURRENT setting in the weld schedules should be input as the required
secondary output current in [kA].

33, the control will operate in SECONDARY PRESET-RANGE MONITORING mode
with Rogowski Coil. When the control operates in this MONITORING mode, the control will
only display the weld current after a weld but will not compensate the current error. The value
of PERCENT CURRENT setting in the weld schedules should be input as the percentage [%]
of maximum current output of the control.

operate in PRIMARY PRESET-RANGE COMPENSATION mode. When the control operates
in this COMPENSATION mode, the value of CURRENT setting in the weld schedules should
be input as the desired secondary current in [kA] value.
