The page 'Settings' contains the radiometer's operational parameters. Operational parameters are those which are assumed to be changed more frequently than the installation parameters on the Setup page.
The page displays a table with the parameters actually set. Each parameter value is a hyper-link to a separate page which lets you change this parameter. This parameter change page shows the actual parameter setting either in an entry field or in a drop down box. You may change the parameter to the desired value and then click to the 'Submit' button to pass the changed value to the radiometer. The radiometer automatically returns to the settings page when the parameter has been changed. To cancel a parameter modification you already started, either use the 'Back' button of you web browser or click to the 'Settings' button on navigation bar. Both returns to the settings page without changing the parameter you edited.
The table below lists the settings provided by this page.
Preset Name
| Parameter Name | Description |
|---|---|
| Preset name | You can name the actual set of parameters (up to 40 characters). If you store the parameter set as a preset, this name acts as a label for the stored preset in the list. |
Antenna Pointing
| Parameter Name | Description |
|---|---|
| AZ Target value | The antenna azimuth pointing. If the radiometer is equipped with a motorized azimuth adjustment, entering a new value lets the antenna move to the selected pointing. Pleased note, that the radiometer takes no readings while the antenna is moving. |
Important Remark: Even if the radiometer has no motorized azimuth adjustment, you should enter the antenna azimuth direction here as precise as possible. The sun outage detection depends on this value. | | EL Target value | The antenna elevation pointing. If the radiometer is equipped with a motorized elevation adjustment, entering a new value lets the antenna move to the selected pointing. Pleased note, that the radiometer takes no readings while the antenna is moving. Important Remark: Even if the radiometer has no motorized elevation adjustment, you should enter the antenna elevation direction here as precise as possible. The sun outage detection depends on this value as well as the correction of the amount of ground temperature contributing to the reading. |
Antenna Temperature Control
Parameter Name --- Description
F/H heater mode --- Setting this to AUTO enables the heed horn temperature control (a simple on/off thermostat with a hysteresis of 2K). OFF switches the feed-horn heater permanently off.
F/H target temperature --- The feed-horn thermostat target temperature.
F/H blower mode --- AUTO selects the automatic control of the feed-horn blower, OFF switches the blower permanently off. In AUTO mode, the feed-horn blower is ON if at least one of the following conditions is true:
F/H blower temp. threshold --- If the feed-horn temperature raises above this threshold, this forces the feed-horn blower to be switched on (provided the F/H blower mode is set to AUTO). If there is no other condition active which switches the feed-horn blower on, it will turn off again if the feed-horn temperature falls 2K below the threshold.
F/H blower rain detection --- If the atmospheric temperature reading of the first radiometer channel exceeds this limit, the radiometer assumes rainfall. This is indicated at the Reading page and forces the feed-horn and reflector blowers to be on. The 'rain' condition remains true for 3 minutes after the radiometer reading again falls below the limit.
RFL heater mode --- Setting this to AUTO enables the reflector temperature control (a simple on/off thermostat with a hysteresis of 2K). OFF switches the reflector heater permanently off.
RFL min. temperature --- This is the reflector thermostat target temperature. The reflector heater switches on if the reflector temperature falls below this value - 1K, switches off when if the temperature raises to 1K above the target value.
RFL heater max. temperature --- The reflector heater switches off, if the temperature of the heater box itself is above this limit (this protects the heater).
RFL blower mode --- AUTO selects the automatic control of the reflector blower, OFF switches the blower permanently off. In AUTO mode, the reflector blower is on if at least one of the following conditions is true:
RFL blower temp. threshold --- If the reflector temperature raises above this threshold, this forces the reflector blower to be switched on (provided the RFL blower mode is set to AUTO). If there is no other condition active which switches the reflector blower on, it will turn off again if the reflector temperature falls 2K below the threshold.
Measurement
| Parameter Name | Description |
|---|---|
| Averaging time | The base integration time of the radiometer front end is one second. The radiometer is capable to apply an additional averaging to the readings which is configured here. The averaging is a simple FIR filter of the specified length (e.g. 5 seconds averaging time means that the displayed reading is the average of the last five values). |
| Sun pos. calculation interval | The time interval when the radiometer re-calculates the sun coordinates for the sun outage detection. 30 seconds is a suitable value in most cases. |
| Sun pos. fault az-diff (+/-) | The radiometer signals a sun outage fault if the calculated sun azimuth and radiometer azimuth differ by less than the value entered here. |
| Sun pos. fault el-diff (+/-) | The radiometer signals a sun outage fault if the calculated sun elevation and radiometer elevation differ by less than the value entered here. |
Miscellaneous
| Parameter Name | Description |
|---|---|
| Case blower OFF | (ON/OFF) Switches the blower inside the radiometer case on or off. |
| Waveguide pressurizer | (ON/OFF) Controls the waveguide pressurizer. |
| Logging to CF card | (ON/OFF) Controls if the radiometer logs it's readings to a compact flash card. |
