6.6.3.9 RPM
The RPM function allows the operator to stop rotation (OFF), select auto or one of three pre-defined
antenna rotation speed.
Note 1
- Antenna speeds are configured at the factory and are enabled or disabled during setting to work.
- The RPM value set by selecting low, normal and high cannot be configured by the operator.
- Depending on the system configuration, different antenna speeds may not be available.
Auto: Automatically selects the optimum antenna RPM for the range mode in use.
Note 1
OFF: Antenna rotation is stopped.
Note 2
Low: Where enabled, the low antenna rotation speed configured during setting to work can
be selected.
- Low speeds increase the probability of target detection whilst reducing the update
rate.
Normal: The standard antenna rotation speed configured during setting to work can be
selected.
- Normal speed offers the best overall detection performance.
High: Where enabled, the high antenna rotation speed configured during setting to work
can be selected.
- High speeds increase the update rate whilst reducing the probability of detection.

There is no Save Changes button or function, any adjustments are immediately adopted.
Note 1: Antenna speed selection is system dependant and is not available on all models. Please consult with Kelvin Hughes
for additional details.
Note 2: Setting the antenna speed to OFF in the RPM menu must NOT be used as a primary means of isolating the antenna
and its sub-systems for safety critical purposes.
