TESTING THE MAT CIRCUITS
1.
Connect the Calibration Unit’s GROUND test lead to a
ground point.
2. Insert a wrist cord into the satellite’s operator jack and
snap it to the parking station. This will enable the
audible alarm circuit needed for calbration verfication.
3. Connect the included stacking snap to the Calibration
Unit’s MAT test lead. Disconnect the satellite from
its mat connection and re-install it to the Calibration
Unit’s stacking snap.
NOTE: The stacking snap must be isolated from the
grounded mat.
