NOTE
It is possible to use a standoff pipe/spool piece supplied by a source other
than Rosemount; however, it is suggested that when the APEX and APEX
Sentry Radar Gauges are mounted, the end of the antenna be no more than
1-inch from the face of the window. For antenna lengths, refer to dimension
“D” in Dimensional Drawings on page A-9.

The APEX and APEX Sentry Radar Gauges are typically factory configured,
so in most situations, gauge adjustments are minimal. To ensure proper
operation, review the following information before installing the gauge. If,
however, your gauge was not configured at the factory, or if you need to
reconfigure the gauge for any reason, please note that the gauge can be
configured on the bench prior to installation or in the field. (Refer to Section 3:
Configuration.)
