The adaptor box isolated current reference signal is calibrated from the factory. No further calibration should be
necessary in the field. If the output current from the machine does not match the commanded current from the
CNC machine, it can be adjusted using the span pot on the WAS4 PRO isolation module. This module is located
inside the adaptor box. To calibrate the current reference use the following procedure.
1. Remove the cover from the adaptor box and locate the WAS4 PRO isolation module.
2. Lift the protective cover from the WAS4 PRO isolation module to expose the ZERO and SPAN
pots. DO NOT adjust the ZERO span pot.
3. Pick a cutting condition that is about 80% of the maximum power supply output current.
4. While making a straight cut, adjust the Span pot on the WAS4 PRO until the output current
from the power supply matches the commanded current. Measure power supply current using
a clamp-on meter or precision shunt attached to the work cable.
