Installing the Em50G in the field.
1. Before installing your sensors and loggers, check the quality of
the cellular communication between the Em50G and local cellular
towers at the location you would like to monitor.
a. Insert the included 5AA batteries into the Em50G and attach
the Em50G antenna.
b. Open ECH2O Utility on your field computer and connect the
Em50G to your computer using the included USB cable.
c. In the “connect via” dropdown menu, select the COM port
containing either “Decagon UCA” or “METER UCA”.
d. Click the “Connect” button in ECH2O Utility.
f. In ECH2O Utility, choose “Cellular Test”.
g. Click the “Test” button. The communication test takes
about 30 s, so please be patient. If cellular coverage is low, try
moving (even just a few meters) to a new location and repeating
the test until you have at least one star of communication.
2. Install your sensors and attach the Em50G in an upright position
to a firm post or PVC pipe, using the included zip ties or similar
fasteners.
3. Install the data logger in a location that will ensure that the solar
panel receives the maximum amount of sunlight. In the northern
hemisphere, this will typically mean that the data logger will face
the south. In the southern hemisphere, this will typically mean that
the data logger will face the north.”
NOTE: Em50/Em50G solar data loggers come with batteries preinstalled. Remove
battery pull-tab to activate batteries. Use only nickel-metal hydride (NiMH) batteries
with the solar Em50/Em50G.
