We have developed the A511 Sensor Test box to facilitate the maintenance of Adcon RTU's in the filed or office. Whether sensors need to be tested, solar panels checked, or SDI-12 sensor addresses modified, the new A511 makes this easy. The old time-consuming process of dragging batteries and adapter cables along, and hook the sensors up to standard testing tools is a thing of the past. This has just become a whole lot easier!
The A511 features the same 5-pin and 7-pin connectors as the Adcon RTU's. Adcon analog sensors, rain gauges and solar panels can thus be connected directly to the A511. To power analog sensors it features an internal 9V battery, which are readily available almost anywhere.
The A511 Sensor Test box comes with a foil keypad and an easy to learn user interface. A comprehensive manual is also included. For a detailed explanation click here.

What can be tested?
- All Adcon compatible analog sensors with an output signal Range between 0 and 2.5V. Test output signal and power
consumption
- Pulse outputs, like rain gauges and water meters
- All Adcon solar panels for the A720, A723, A731, A732, A733
series of RTU's: check Volts and mA's
- Checking and changing addresses on SDI-12 sensors, which
- support addresses according to the SDI-12 standard,
- can be powered with a 9V battery, or
- have their own internal power supply.

The A511 Sensor-Testbox in Detail:
Checking analog Sensors:
Several types of measurements are available:
- permanent, instantaneous monitoring
- averaging
- simulating an Adcon RTU
Since the A511 features 2 7-pin signal connectors you can simultaneously connect up to 6 analog sensors. According to the Adcon cabling convention each of the two 7-pin Ports supports three analog sensors.
This is certainly a convenient feature when it comes to testing combi-sensors, like the Adcon Temperature / Humidity sensor, the Adcon Wind speed and direction sensors, and certainly the Sentek and C-Probe multilevel soil moisture sensors.
You can furthermore test the current consumption of all sensors attached. This is particularly handy to detect faulty sensors, drawing too much current and thus emptying the battery.
Checking Solar Panels:
Check the output voltage and the charging current of all standard Adcon solar panels. This will let you easily detect a problem with a solar panel.
Checking Pulse Counters:
To test rain gauges and water meters, which output pulses by means of standard reed switches. Simply create a defined number of pulses and check the display of your A511. As long as the reed switch is connected the device will sum the pulses received. 2 rain gauges can be connected simultaneously.
Changing the address of SDI-12 Sensors:
The A511 Sensor Test box lets you connect SDI-12 sensors to see which address they are set to, and change it, if necessary. This is of particular importance if you want to run several sensors off the same RTU, but don't know which address they are set to. Since there is no SDI-12 standard connector, the optional adapter cable features cable clamps to hold bare wires.
