For N8486AQ power sensor only.
When connecting the waveguide flange to the power sensor, make sure you follow the
following procedures to avoid any damage to the precision waveguide flange:
1 Torque the waveguide flange’s screws to < 3.75 lb-in (maximum).
2 Insert the two screws as indicated in Figure 1-3 located at the side of the flange. Insert
the remaining two screws to either side of the flange. Tighten the four screws until
finger tight.
3 Tighten the flange using a calibrated torque wrench by going back and forth between
each screws that are opposite to each others. Tighten each screw with a small
incremental torque until the desired torque is achieved.
If you are using the hex ball driver, hold the driver with your thumb and forefinger to
avoid excess torque. You must extremely carefull not to over-torque when using the hex
ball driver, and do not fully torque one screw before tightening the others.
Insert this screw, and the
one opposite (hidden under
the instrument) as shown in
the diagram.
